The cryo-EM structure of the bd oxidase from M. tuberculosis reveals a unique structural framework and enables rational drug design to combat TB.
New drugs are urgently needed to combat the global TB epidemic. Targeting simultaneously multiple respiratory enzyme complexes of Mycobacterium tuberculosis is regarded as one of the most effective treatment options to shorten drug administration regimes, and reduce the opportunity for the emergence of drug resistance. During infection and proliferation, the cytochrome bd oxidase plays a crucial role for mycobacterial pathophysiology by maintaining aerobic respiration at limited oxygen concentrations. Here, we present the cryo-EM structure of the cytochrome bd oxidase from M. tuberculosis at 2.5 Å. In conjunction with atomistic molecular dynamics (MD) simulation studies we discovered a previously unknown MK-9-binding site, as well as a unique disulfide bond within the Q-loop domain that defines an inactive conformation of the canonical quinol oxidation site in Actinobacteria. Our detailed insights into the long-sought atomic framework of the cytochrome bd oxidase from M. tuberculosis will form the basis for the design of highly specific drugs to act on this enzyme.

Reclassification of Arthrobacter endophyticus (Wang et al. 2015) as Glutamicibacter endophyticus comb. nov.
The species Arthrobacterendophyticus is phylogenetically placed within the Glutamicibacter clade and shares 97.3-98.4 % 16S rRNA gene sequence similarities with the species of this genus. The quinone system with the major menaquinone MK-9 and the peptidoglycan amino acids alanine, glutamic acid and lysine are consistent with the characteristics of the members of the genus Glutamicibacter but the polar lipid profile with phosphatidylinositol distinguishes A. endophyticus from species of the genus Glutamicibacter. Re-analysis of both peptidoglycan structure and polar lipid profile revealed peptidoglycan type l-Lys-l-Ala-l-Glu (A11.35) and a polar lipid profile lacking phosphatidylinositol. These traits are consistent with those of representatives of the genus Glutamicibacter and distinguish A. endophyticus from members of the genus Arthrobacter sensu stricto. Due to its phylogenetic position and congruence with the key characteristics of members of the genus Glutamicibacter we here propose the reclassification of Arthrobacter endophyticus as a species of the genus Glutamicibacter, Glutamicibacter endophyticus comb. nov.

Three novel species of the genus Kibdelosporangium; Kibdelosporangium kanagawaense sp. nov., Kibdelosporangiumrhizosphaerae sp. nov. and Kibdelosporangium rhizovicinum sp. nov.
The taxonomic positions of three actinomycete isolates, K08-0175T, K10-0543T and K12-0791T, which were isolated from plant root and rhizospheric soil samples were subjected to a polyphasic taxonomic study. On the basis of the results of phylogenetic analysis and morphological and chemotaxonomic characteristics, these three strains were classified as representing members of the genus Kibdelosporangium. These strains were observed to produce both long chains of rod-shaped spores and sporangium-like structures with well-defined walls on aerial hyphae. Phylogenetic position, DNA-DNA hybridization and comparison of the phylogenetically closest relatives revealed that these three strains were clearly distinguishable from each other and from their closest phylogenetic relatives. Therefore, three novel species are proposed as Kibdelosporangium kanagawaense sp. nov. [type strain K08-0175T (=NBRC 112388T=TBRC 6786T)], Kibdelosporangiumrhizosphaerae sp. nov.

A Gram-stain positive, non-spore-forming, non-motile, facultatively anaerobic bacterial strain, designated CAU 1319T, was isolated from sea sand and the strain's taxonomic position was investigated using a polyphasic approach. Strain CAU 1319T grew optimally at 30 °C and at pH 7.5 in the presence of 2 % (w/v) NaCl. Phylogenetic analysis, based on the 16S rRNA gene sequence, revealed that strain CAU 1319T belongs to the genus Tessaracoccus, and is closely related to Tessaracoccus lapidicaptus IPBSL-7T (similarity 97.69 %), Tessaracoccus bendigoensis Ben 106T (similarity 95.64 %) and Tessaracoccus flavescens SST-39T (similarity 95.84 %). Strain CAU 1319T had ll-diaminopimelic acid as the diagnostic diamino acid in the cell-wall peptidoglycan, MK-9 (H4) as the predominant menaquinone, and anteiso-C15 : 0 as the major fatty acid. The polar lipids consisted of phosphatidylglycerol, phosphatidylinositol, two unidentified aminolipids, three unidentified phospholipids and one unidentified glycolipid. Predominant polyamines were spermine and spermidine. The DNA-DNA hybridization value between strain CAU 1319T and T. lapidicaptus IPBSL-7T was 24 %±0.2. The DNA G+C content of the novel strain was 69.5 mol%. On the basis of phenotypic and chemotaxonomic properties, as well as phylogenetic relatedness, strain CAU 1319Tshould be classified as a novel species of the genus Tessaracoccus, for which the name Tessaracoccus arenae sp. nov. is proposed.

Lentzea cavernae sp. nov., an actinobacterium isolated from a karst cave sample, and emended description of the genus Lentzea.
A novel actinobacterial strain, designated SYSU K10001T, was isolated from a limestone sample collected from a karst cave in Xingyi county, Guizhou province, south-western China. The taxonomic position of the strain was investigated using a polyphasic approach. Cells of the strain were aerobic and Gram-stain-positive. On the basis of 16S rRNA gene sequence analysis, strain SYSU K10001T was most closely related to the type strains of the genus Lentzea, Lentzea albida NBRC 16102T (98.8 % similarity) and Lentzea waywayandensis NRRL B-16159T (98.6 %), and is therefore considered to represent a member of the genus Lentzea. DNA-DNA hybridization values between strain SYSU K10001T and related type strains of the genus Lentzea were less than 70 %. In addition, meso-diaminopimelic acid was the diagnostic diamino acid in the cell-wall peptidoglycan. The whole-cell sugars were arabinose, fructose, mannose and xylose. The major isoprenoid quinone was MK-9(H4), while the major fatty acids (>10 %) were iso-C16 : 0 and C14 : 0. The polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, hydroxy-phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol mannoside, one unidentified phospholipid and one unidentified lipid. The genomic DNA G+C content of strain SYSU K10001T was 69.4 mol%. On the basis of phenotypic, genotypic and phylogenetic data, strain SYSU K10001T represents a novel species of the genus Lentzea, for which the name Lentzea cavernae sp. nov. is proposed. The type strain is SYSU K10001T (=KCTC 39804T=CGMCC 4.7367T=NBRC 112394T).

Dictyobacter aurantiacus gen. nov., sp. nov., a member of the family Ktedonobacteraceae, isolated from soil, and emended description of the genus Thermosporothrix.
A mesophilic, Gram-stain-positive, spore-forming bacterium that formed branched mycelia was isolated from paddy soil in Gunung Salak (Mount Salak), West Java, Indonesia. This strain, designated S-27T, grew at temperatures between 20 and 37 °C; the optimum growth temperature was 25 to 30 °C, and no growth was observed at 15 or 45 °C. The pH range for growth was pH 3.5 to 8.6; the optimum pH was 6.0, and no growth was observed at pH 3.0 or 9.2. Strain S-27T was able to hydrolyse polysaccharides such as starch, cellulose and xylan. The G+C content of the DNA of strain S-27T was 55.7 mol%. The major fatty acids were iso-C17 : 0 and C16 : 1 2-OH, and the major menaquinone was MK-9 (H2). The cell wall of strain S-27T contained d-glutamic acid, glycine, l-alanine, d-alanine, l-ornithine and β-alanine in a molar ratio of 1.0 : 1.6 : 1.4 : 0.6 : 0.9 : 1.1.

On the basis of 16S rRNA gene sequence analysis it was shown that strain 9H-4T belongs to the genus Aeromicrobium with Aeromicrobium flavumTYLN1T (98.7 % similarity) and Aeromicrobium tamlenseSSW1-57T (98.4 %) as the nearest neighbours and forms a separate branch in a neighbour-joining phylogenetic tree based on 16S rRNA gene sequences. DNA-DNA hybridizations confirmed its novel species identity based on 39 and 46 % DNA-DNA relatedness with A. flavum DSM 19355T and A. tamlense DSM 19087T, respectively. The predominant menaquinone of strain 9H-4T was MK-9(H4). The peptidoglycan contained ll-diaminopimelic acid as the diagnostic diamino acid. The major fatty acids (C18 : 1ω9c, 10-methyl C18 : 0, C16 : 0, C18 : 0, C16 : 0 2-OH) were consistent with the fatty acid patterns reported for members of the genus Aeromicrobium. The DNA G+C content of strain 9H-4T was 70.8 mol%. The distinct genotypic, chemotaxonomic, physiological and biochemical characteristics support the classification of strain 9H-4T as a representative of a novel species of the genus Aeromicrobium, for which the name Aeromicrobium choanae sp. nov. is proposed. The type strain is 9H-4T (=ZIM B1021T=LMG 29165T=CCM 8650T).

The isolate was found to grow at NaCl concentrations of 0-5 % (w/v) (optimum: 0 %), 10-45 °C (optimum: 30-35 °C) and pH 5.0-9.0 (optimum: pH 6.0) on tryptic soy agar. Analysis of the 16S rRNA gene sequence indicated that the isolate belonged to the genus Acinetobacter and was most closely related to Acinetobacter rudis LMG 26107T, Acinetobacter guillouiae LMG 988T and Acinetobacter bereziniae LMG 1003T with 96.4, 96.3 and 96.3 % sequence similarity, respectively. The comparative sequence analyses of the rpoB and gyrB genes showed that BRTC-1T is distant from the species of the genus Acinetobacter with validly published names (≤84.0 and ≤82.0 % similarity, respectively). The average nucleotide identity and digital DNA-DNA hybridization values (≤77.0 and ≤22.8 %, respectively) between the whole-genome sequence of BRTC-1T and those of the known taxa were far below the thresholds used to discriminate bacterial species. The major fatty acids were determined to be C16 : 0, C18 : 1ω9c and C16 : 1ω7c/iso-C15 : 0 2-OH. The respiratory quinone was Q-9. The polar lipids were found to be diphosphatidyglycerol, phosphatidylglycerol, phosphatidylethanolamine, five phospholipids and one phosphatidylcholine. Based on its phenotypic and chemotaxonomic characteristics from this study, the isolate is concluded to represent a novel species of the genus Acinetobacter, for which the name Acinetobacter larvae sp. nov. is proposed.

Reclassification of Arthrobacter sanguinis (Mages et al. 2009) as Haematomicrobium sanguinis gen. nov., comb. nov.
Due to its separate position within the genus Arthrobacter in many published phylogenetic trees and its incomplete chemotaxonomic characterization, the type strain of Arthrobacter sanguinis was subjected to analysis of its chemotaxonomic traits including quinone system, polar lipid profile, peptidoglycan structure and fatty acid profile. The fatty acid profile consisted of the major compounds (>10 %) iso-C15 : 0, anteiso-C15 : 0 and anteiso-C17 : 0. It showed a quinone system with the predominating menaquinone MK-9(H2). Both, fatty acid profile and quinone system are in line with the description of the genus Arthrobacter. The peptidoglycan type was l-Lys-l-Ala-Gly (A11.50) which is unique within the genus Arthrobacter sensu lato and also among species of the genus Arthrobacter recently reclassified in the genera Sinomonas, Paenarthrobacter and Pseudarthrobacter. The polar lipid profile was very complex and unique among the group of taxa in containing relatively high proportions of several unidentified lipids. In conclusion from the phylogenetic position and chemotaxonomic distinguishability from related taxa, the reclassification of Arthrobacter sanguinis in a new genus and species, Haematomicrobium sanguinis gen. nov., comb. nov., is proposed. The type strain of the type species is 741T (=CCUG 46407T=DSM 21259T).

Streptosporangium saharense sp. nov., an actinobacterium isolated from Saharan soil.
A novel actinobacterium, designated strain SG20T, was isolated from a Saharan soil sample collected from Béni-isguen (Mzab), Ghardaïa province, southern Algeria. The micro-organism developed small roundish sporangia on aerial mycelium that were sessile or carried by very short sporangiophores. The cell-wall peptidoglycan contained meso-diaminopimelic acid and the whole-cell sugars comprised glucose, ribose and mannose, but madurose was not detected. The predominant menaquinones were MK-9(H4), MK-9(H6) and MK-9(H2). The major fatty acids were iso-C16 : 0 and C16 : 0. The phospholipids detected were diphosphatidylglycerol, phosphatidylinositol, phosphatidylethanolamine and unknown lipids. The phenotypic and chemotaxonomic characteristics of the novel strain resembled those of recognized members of the genus Streptosporangium. Moreover, phylogenetic analysis based on a 16S rRNA gene sequence generated from the strain identified its closest relative as Streptosporangium jomthongense BCC 53154T (98.5 % similarity), which produces single spores on aerial mycelium, but no sporangia. In hybridization experiments, the DNA-DNA relatedness values recorded between strain SG20T and S. jomthongense DSM 46822T fell well below 70 %. On the basis of phenotypic and genotypic data, strain SG20T can be distinguished as representing a novel species of the genus Streptosporangium, for which the name Streptosporangium saharense sp. nov. is proposed. The type strain is SG20T ( = DSM 46743T = CECT 8840T).

The actinomycete strain N74T, isolated from cave soil, was studied using a polyphasic taxonomic approach. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain N74T formed a stable, distinct lineage cluster together with Microbispora thailandensis NN276T (99.3% similarity) and Microbispora mesophila JCM 3151T (97.5%). Strain N74T was observed to produce single spherical spores on aerial mycelium as reported for M. mesophila JCM 3151T and M. thailandensis NN276T but different from other known species of the genus Microbispora, which are characterized by pairs of spores on aerial hyphae. Multilocus sequence analyses based on concatenated partial gyrB, rpoB, atpD, recA and 16S rRNA gene sequences showed a clear distinction of strain N74T, M. mesophila JCM 3151T and M. thailandensis NN276T from other members of the genus Microbispora, although the chemotaxonomic characteristics of strain N74T were similar to the genus Microbispora; the cell wall contained meso-diaminopimelic acid and the whole-cell hydrolysate contained madurose as the diagnostic sugar. The major menaquinone was MK-9(H4). The fatty acid profile contained iso-C16:0. On the basis of morphological, chemotaxonomic and phylogenetic evidence, strain N74T is assigned to a novel species of a new genus, for which the name Sphaerimonospora cavernae gen. nov., sp. nov. is proposed. The type strain of Sphaerimonospora cavernae is N74T (=BCC 77604T=NBRC 111481T). It is also proposed that M. mesophila and M. thailandensis be transferred to this genus as Sphaerimonospora mesophila comb. nov.

Streptosporangium jiaoheense sp. nov. and Streptosporangium taraxaci sp. nov., actinobacteria isolated from soil and dandelion root (Taraxacum mongolicum Hand.-Mazz.).
Two novel actinobacteria, designated strains NEAU-Jh1-4T and NEAU-Wp2-0T, were isolated from muddy soil collected from a riverbank in Jiaohe and a dandelion root collected from Harbin, respectively. A polyphasic study was carried out to establish the taxonomic positions of these two strains. The phylogenetic analysis based on the 16S rRNA gene sequences of strains NEAU-Jh1-4T and NEAU-Wp2-0T indicated that strain NEAU-Jh1-4T clustered with Streptosporangium nanhuense NEAU-NH11T (99.32 % 16S rRNA gene sequence similarity), Streptosporangium purpuratum CY-15110T (98.30 %) and Streptosporangium yunnanense CY-11007T (97.95 %) and strain NEAU-Wp2-0T clustered with 'Streptosporangium sonchi ' NEAU-QS7 (99.39 %), 'Streptosporangium kronopolitis' NEAU-ML10 (99.26 %), 'Streptosporangium shengliense' NEAU-GH7 (98.85 %) and Streptosporangium longisporum DSM 43180T (98.69 %). Moreover, morphological and chemotaxonomic properties of the two isolates also confirmed their affiliation to the genus Streptosporangium. However, the low level of DNA-DNA hybridization and some phenotypic characteristics allowed the isolates to be differentiated from the most closely related species. Therefore, it is proposed that strains NEAU-Jh1-4T and NEAU-Wp2-0T represent two novel species of the genus Streptosporangium, for which the name Streptosporangium jiaoheense sp. nov. and Streptosporangium taraxaci sp. nov. are proposed. The type strains are NEAU-Jh1-4T (=CGMCC 4.7213T=JCM 30348T) and NEAU-Wp2-0T (=CGMCC 4.7217T=JCM 30349T), respectively.

Isoptericola cucumis sp. nov., isolated from the root tissue of cucumber (Cucumis sativus).
A Gram-stain-positive, aerobic organism, showing an irregular cell morphology, was isolated from the root tissue of cucumber (Cucumis sativus) and investigated in detail for its taxonomic position. On the basis of the 16S rRNA gene sequence analysis, strain AP-38T was shown to be most closely related to Isoptericola variabilis (99.1 %) and Isoptericola nanjingensis (98.9 %). The 16S rRNA gene sequence similarity to all other species of the genus Isoptericola was ≤98.5 %. DNA-DNA relatedness to Isoptericola variablis DSM 10177T and Isoptericola nanjingensis DSM 24300T was 31(reciprocal 41 %) and 34 (reciprocal 34 %), respectively. The diagnostic diamino acid of the peptidoglycan was l-lysine. The quinone system contained predominantly menaquinones MK-9(H4) and MK-9(H2). In the polar lipid profile, major compounds were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol and two phosphatidylinositol mannosides. The polyamine pattern contained the major components spermidine and spermine and significant amounts of tyramine. In the fatty acid profile, anteiso-C15 : 0 and iso-C15 : 0 were present in major amounts. These data support the allocation of the strain to the genus Isoptericola. The results of physiological and biochemical characterization additionally provide phenotypic differentiation of strain AP-38T from I. variabilis and I. nanjingensis. AP-38T represents a novel species of the genus Isoptericola, for which we propose the name Isoptericola cucumis sp. nov., with AP-38T (= LMG 29223T=CCM 8653T) as the type strain.

Phylogenetic analysis showed that strain TRM 46794-61T had a 16S rRNA gene sequence similarity of 97.6 % with the most closely related species with a validly published name, Streptomyces aidingensis TRM 46012T, and it could be distinguished from all species in the genus Streptomyces based on data from this polyphasic taxonomic study. However, DNA-DNA hybridization studies between strain TRM 46794-61T and S.aidingensis TRM 46012T showed only 45.4 % relatedness. On the basis of these data, strain TRM 46794-61T should be designated as a representative of a novel species of the genus Streptomyces, for which the name Streptomyces canalis sp. nov. is proposed.

Streptomyces verrucosisporus sp. nov., isolated from marine sediments.
Five actinomycete isolates, CPB1-1T, CPB2-10, BM1-4, CPB3-1 and CPB1-18, belonging to the genus Streptomyces were isolated from marine sediments collected from Chumphon Province, Thailand. They produced open loops of warty spore chains on aerial mycelia. ll-Diaminopimelic acid, glucose and ribose were found in their whole-cell hydrolysates. Polar lipids found were diphosphatidylglycerol, phosphatidylethanolamine, lysophosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositol and phosphatidylinositol mannoside. Menaquinones were MK-9(H6), MK-9(H8), MK-10(H6) and MK-10(H8). Major cellular fatty acids were anteiso-C15 : 0, anteiso-C17 : 0 and iso-C16 : 0. The taxonomic position of the strains was described using a polyphasic approach. blastn analysis of the 16S rRNA gene sequence revealed that these five strains exhibited the highest similarities with 'Streptomyces mangrovicola' GY1 (99.0 %), Streptomyces fenghuangensisGIMN4.003T (98.6 %), Streptomyces barkulensisRC 1831T (98.5 %) and Streptomyces radiopugnans R97T (98.3 %).

Microlunatus nigridraconis sp. nov., an actinobacterium from rhizosphere soil.
An actinobacterium, designated strain CPCC 203993T, was isolated from a rhizosphere soil sample collected from Heilongjiang Province, northeast China, and was characterized using a polyphasic taxonomy approach. Cells of the strain were Gram-stain-positive, non-motile and non-endospore-forming cocci. The 16S rRNA gene sequence comparison of strain CPCC 203993T with members of the genus Microlunatus yielded 93.9 % to 97.8 % similarities. In the phylogenetic tree based on 16S rRNA gene sequences, strain CPCC 203993T was affiliated to the clade of the genus Microlunatus next to Microlunatus parietis DSM 22083T, while the DNA-DNA hybridization value of 31.5 % (±1.8 %) between strain CPCC 203993T and Microlunatus. parietis DSM 22083T was far below 70 %. This result indicated that strain CPCC 203993T represented a different genomic species from M. parietis. Chemotaxonomically, the strain contained ll-2,6-diaminopimelic acid as the diagnostic diamino acid, MK-9(H4) as the only menaquinone, diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, three unidentified glycolipids and one unidentified phospholipid in the polar lipids extracts, and anteiso-C15 : 0, iso-C15 : 0 and iso-C16 : 0 as the major cellular fatty acids, without mycolic acids. The genomic DNA G+C content was 64.04 mol%. The above evidence from the polyphasic study merit the recognition of strain CPCC 203993T as a representative of a novel species of the genus Microlunatus, for which Microlunatus nigridraconis sp. nov. is proposed.

The main cellular fatty acids were anteiso-C15 : 0, iso-C15 : 0, C16 : 0 and iso-C16 : 0. An analysis of an almost complete 16S rRNA gene sequence showed that the strain shared the highest levels of sequence similarity with Streptomyces sannanensisKC-7038T (97.87 %), Streptomyces hebeiensis YIM 001T (97.84 %), Streptomyces pathocidini NBRC 13812T (97.80 %), Streptomyces cocklensis BK168T (97.25 %), Streptomyces coerulescens NBRC 12758T (97.12 %), Streptomyces aurantiogriseus NBRC 12842T (97.06 %) and Streptomyces rimosussubsp. rimosus ATCC 10970T (97.04 %). The DNA G+C content of the genomic DNA of strain Js-1T was 70.1 mol%. Furthermore, DNA-DNA hybridization tests revealed that the relatedness values between strain Js-1T and the most closely related species ranged from 15.10 to 47.20 %. Based on its phenotypic and genotypic characteristics, strain Js-1T (=CCTCC M 2011365T=JCM 30846T) is considered to represent a novel species within the genus Streptomyces, which we classified as Streptomycestremellae sp. nov.

Streptomyces lacrimifluminis sp. nov., a novel actinobacterium that produces antibacterial compounds, isolated from soil.
A novel actinobacterial strain, designated Z1027T, was isolated from a soil sample collected near the Tuotuo River, Qinghai-Tibet Plateau (China). The strain exhibited antibacterial activity against Escherichia coli and Staphylococcus aureus. The taxonomic position of strain Z1027T was determined using a polyphasic approach. The organism had chemotaxonomic and morphological properties consistent with its classification in the genus Streptomyces and formed a distinct phyletic line in the 16S rRNA gene tree, together with Streptomyces turgidiscabies ATCC 700248T (99.19 % similarity), Streptomyces graminilatus JL-6T (98.84 %) and Streptomyces reticuliscabiei CFBP 4531T (98.36 %). The genomic DNA G+C content of strain Z1027T was 74±1 mol%. The DNA-DNA relatedness values between strain Z1027T and Streptomyces turgidiscabies ATCC 700248T and Streptomyces reticuliscabiei CFBP 4531T were 38.5±0.4 and 26.2±1.2 %, respectively, both of them significantly lower than 70 %. Chemotaxonomic data revealed that strain Z1027T possessed MK-9(H6) and MK-9(H8) as the major menaquinones, ll-diaminopimelic acid as the diagnostic diamino acid and galactose as a whole-cell sugar. Diphosphatidylglycerol, phosphatidylethanolamine, phosphatydilinositol and seven other unknown polar lipids were detected; iso-C16 : 0, summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) and C16 : 0 were the major fatty acids. On the basis of these genotypic and phenotypic data, it is proposed that isolate Z1027T (=CGMCC 4.7272T=JCM 31054T) should be classified as the type strain of a novel species of the genus Streptomyces,Streptomyces lacrimifluminis sp. nov.

Tersicoccus solisilvae sp., nov., a bacterium isolated from forest soil.
A Gram-stain-positive, aerobic, non-motile, coccoid bacterial strain, 36AT, was isolated from Munnar, in India. Based on the results of 16S rRNA gene sequence analysis, this strain was identified as representing a member of the genus Tersicoccus and was most closely related to the type strain of Tersicoccus phoenicis (98.9 %, sequence similarity), the only other member of the genus, and to members of the related genus Arthrobacter (<96.1 %, sequence similarity). However, the DNA-DNA relatedness of strain 36AT with T. phoenicis DSM 30849T was only 31.9±0.8. The DNA G+C content of strain 36AT was 70.9 mol%. Strain 36AT was an aerobic microbe with optimal growth at 37 °C, pH 6.0-8.0 and NaCl 0.5-3 % (w/v). Cell-wall peptidoglycan of strain 36AT was of type A11.20 (Lys-Ser-Ala2). Polar lipids present were phosphatidylglycerol, diphosphatidylglycerol, phosphatidylinositol, two phospholipids, a glycolipid and four unknown lipids. The major isoprenoid quinones were MK-9 (H2) and MK-8 (H2). Major fatty acids of strain 36AT were anteiso-C15 : 0, anteiso-C17 : 0, iso-C16 : 0 and iso-C15 : 0. The results of phylogenetic, chemotaxonomic and biochemical tests allowed a clear differentiation of strain 36AT, which represents a novel member of the genus Tersicoccus, for which the name Tersicoccus solisilvae sp. nov., is proposed. The type strain is 36AT (=KCTC 33776T=CGMCC 1.15480T).

Saccharomonospora xiaoerkulensis sp. nov., isolated from lake sediment.
A novel actinomycete, strain TRM 41495T, was isolated from lake sediment of Xiaoerkule lake in Xinjiang province, China, and was examined using a polyphasic approach. Strain TRM 41495T was aerobic, Gram-stain-positive, growing best on ISP medium 7 with abundant white aerial mycelium formed and brown soluble pigments produced. The optimum NaCl concentration for growth was 3.0 % (w/v), and the optimum temperature for growth was 37 °C. On the basis of 16S rRNA gene sequence analysis, strain TRM 41495T was shown to belong to the genus Saccharomonospora with a sequence similarity of 97.50 % with the most closely related species, Saccharomonospora xinjiangensis. The organism had chemical and morphological features typical of the genus Saccharomonospora. The cell wall of strain TRM 41495T contained meso-diaminopimelic acid, and galactose, arabinose, ribose and mannose were the major whole-cell sugars. The polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, phosphatidylinositol and an unknown phosphoglycolipid. The predominant menaquinones were MK-9(H4) and MK-9(H2). The major fatty acids were iso-C16 : 0, C16 : 0, C17 : 1ω6c, anteiso-C17 : 0 and iso-C16 : 1H. The G+C content of the DNA was 72.9 mol%. However, DNA-DNA hybridization studies between strain TRM 41495T and Saccharomonospora xinjiangensis showed only 43.9 % relatedness. Whole-cell sugars, menaquinones and fatty acids differentiate strain TRM 41495T from Saccharomonospora xinjiangensis. On the basis of the polyphasic evidence, strain TRM 41495T represents a novel species of the genus Saccharomonospora, for which the name Saccharomonospora xiaoerkulensis sp. nov. is proposed.

A Gram-stain-positive, short-rod, aerobic bacterium, designated as strain LAM9155T, was isolated from saline soil sample collected from Lingxian County, Shandong Province, PR China. The strain grew optimally at 25-30 °C, pH 7.0 and 0.5 % (w/v) NaCl. The 16S rRNA gene sequence analysis revealed that strain LAM9155T belonged to the genus Frigoribacterium and was closely related to Frigoribacteriumendophyticum EGI 6500707T (99.4 %), Frigoribacteriumfaeni 801T (98.6 %) and Frigoribacteriummesophilum MSL-08T (96.2 %). The DNA-DNA hybridization values between strain LAM9155T and F. endophyticum JCM 30093T and between strain LAM9155T and F. faeni DSM 10309T were 40.2±2.1 and 32.8±1.6 %, respectively. The major fatty acids of LAM9155T were anteiso-C15 : 0, anteiso-C17 : 0 and iso-C16 : 0. The cell-wall analysis showed the B-type peptidoglycan containing alanine, glutamate, glycine, serine and lysine and that the cell wall contained the sugars galactose and ribose. The genomic DNA G+C content of strain LAM9155T was 68.2 mol%. The predominant menaquinone was MK-9. The main polar lipids were diphosphatidylglycerol, phosphatidylglycerol, one unknown glycolipid and four unknown lipids. Based on the DNA-DNA hybridization and phenotypic, phylogenetic and chemotaxonomic properties, strain LAM9155T could be distinguished from the recognized species of the genus Frigoribacterium and was suggested to represent a novel species, for which the name Frigoribacterium salinisoli sp. nov. is proposed. The type strain is LAM9155T (=ACCC 19902T=JCM 30848T). Moreover, the transfer of F. mesophilum Dastager et al. 2008 to Parafrigoribacterium gen. nov. as Parafrigoribacterium mesophilum comb. nov.

Streptomyces kronopolitis sp. nov., an actinomycete that produces phoslactomycins isolated from a millipede (Kronopolites svenhedind Verhoeff).
A phoslactomycin-producing actinomycete, designated strain NEAU-ML8T, was isolated from a millipede (Kronopolites svenhedind Verhoeff) and characterized using a polyphasic approach. 16S rRNA gene sequence analysis showed that strain NEAU-ML8T belongs to the genus Streptomyces with the highest sequence similarities to Streptomyces lydicus NBRC 13058T (99.39 %) and Streptomyces chattanoogensis DSM 40002T (99.25 %). The maximum-likelihood phylogenetic tree based on 16S rRNA gene sequences showed that the isolate formed a distinct phyletic line with NBRC 13058T and S. chattanoogensis DSM 40002T. This branching pattern was also supported by the tree rconstructed with the neighbour-joining method. A combination of DNA-DNA hybridization experiments and phenotypic tests were carried out between strain NEAU-ML8T and its phylogenetically closely related strains, which further clarified their relatedness and demonstrated that NEAU-ML8T could be distinguished from NBRC 13058T and S. chattanoogensis DSM 40002T. Therefore, it is concluded that strain NEAU-ML8T can be classified as representing a novel species of the genus Streptomyces, for which the name Streptomyces kronopolitis sp. nov. is proposed. The type strain is NEAU-ML8T (=DSM 101986T=CGMCC 4.7323T).

Verrucosispora sonchi sp. nov., a novel endophytic actinobacterium isolated from the leaves of common sowthistle (Sonchus oleraceus L.).
A novel actinobacterium, designated strain NEAU-QY3T, was isolated from the leaves of Sonchus oleraceus L. and examined using a polyphasic taxonomic approach. The organism formed single spores with smooth surface on substrate mycelia. Phylogenetic analysis based on the 16S rRNA gene sequence indicated that the strain had a close association with the genus Verrucosispora and shared the highest sequence similarity with Verrucosispora qiuiae RtIII47T (99.17 %), an association that was supported by a bootstrap value of 94 % in the neighbour-joining tree and also recovered with the maximum-likelihood algorithm. The strain also showed high 16S rRNA gene sequence similarities to Xiangella phaseoli NEAU-J5T (98.78 %), Jishengella endophytica 202201T (98.51 %), Micromonospora eburnea LK2-10T (98.28 %), Verrucosispora lutea YIM 013T (98.23 %) and Salinispora pacifica CNR-114T (98.23 %). Furthermore, phylogenetic analysis based on the gyrB gene sequences supported the conclusion that strain NEAU-QY3T should be assigned to the genus Verrucosispora. However, the DNA-DNA hybridization relatedness values between strain NEAU-QY3T and V. qiuiae RtIII47T and V. lutea YIM 013T were below 70 %. With reference to phenotypic characteristics, phylogenetic data and DNA-DNA hybridization results, strain NEAU-QY3T was readily distinguished from its most closely related strains and classified as a new species, for which the name Verrucosispora sonchi sp. nov. is proposed. The type strain is NEAU-QY3T (=CGMCC 4.7312T=DSM 101530T).

Raineyella antarctica gen. nov., sp. nov., a psychrotolerant, d-amino-acid-utilizing anaerobe isolated from two geographic locations of the Southern Hemisphere.
A Gram-stain-positive bacterium, strain LZ-22T, was isolated from a rhizosphere of moss Leptobryum sp. collected at the shore of Lake Zub in Antarctica. Cells were motile, straight or pleomorphic rods with sizes of 0.6-1.0×3.5-10 µm. The novel isolate was a facultatively anaerobic, catalase-positive, psychrotolerant mesophile. Growth was observed at 3-41 °C (optimum 24-28 °C), with 0-7 % (w/v) NaCl (optimum 0.25 %) and at pH 4.0-9.0 (optimum pH 7.8). The quinone system of strain LZ-22T possessed predominately menaquinone MK-9(H4). The genomic G+C content was 70.2 mol%. Strain 10J was isolated from a biofilm of sediment microbial fuel cell, in Uruguay and had 99 % 16S rRNA gene sequence similarity to strain LZ-22T. DNA-DNA-hybridization values of 84 % confirmed that both strains belonged to the same species. Both strains grew on sugars, proteinaceous compounds, and some amino- and organic acids. Strain LZ-22T uniquely grew on D-enantiomers of histidine and valine while neglecting growth on L-enantiomers. Both strains were sensitive to most of the tested antibiotics but resistant to tested nitrofurans and sulfanilamides. Phylogenetic analyses of the 16S rRNA gene sequences indicated that the strains were related to members of the family Propionibacteriaceae (~93-94 % 16S rRNA gene sequence similarity) with formation of a separate branch within the radiation of the genera Granulicoccus and Luteococcus. Based on phenotypic and genotypic characteristics, we propose the affiliation of both strains into a novel species of a new genus. The name Raineyella antarctica gen. nov., sp. nov. is proposed for the novel taxon with the type strain LZ-22T (=ATCC TSD-18T=DSM 100494T=JCM 30886T).

Neither storage compounds nor extensive internal membranes were observed in the cells. Strain gps52(T) grew using carbon dioxide fixation and oxidation of inorganic sulfur compounds with oxygen as electron acceptor. Optimal growth was observed at 32 °C, pH 6.5 and with 3 % (w/v) NaCl. Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain gps52(T) belongs to the family Ectothiorhodospiraceae and is different from any other known bacteria, with sequence similarities of less than 93 %. Based on phenotypic and phylogenetic findings, the isolate is considered to represent a novel genus and species in the family Ectothiorhodospiraceae, and the name Thiogranum longum gen. nov., sp. nov. is proposed. The type strain is gps52(T) ( = NBRC 101260(T) = DSM 19610(T)). An emended description of the genus Thiohalomonas is also proposed.

The polar lipids comprised diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol and three glycolipids. Cell-wall analysis revealed that the peptidoglycan type was A3α, based on l-lysine-l-alanine; the cell-wall sugars were galactose and mannose. The genomic G+C content of strain A33(T) was 66.8 mol%. The low DNA-DNA relatedness values between strain A33(T) and recognized species of the genus Arthrobacter and many phenotypic properties supported the classification of strain A33(T) as a representative of a novel species of the genus Arthrobacter, for which the name Arthrobacter nanjingensis sp. nov. is proposed.

Description of Kribbella italica sp. nov., isolated from a Roman catacomb.
A novel actinobacterium, strain BC637(T), was isolated from a biodeteriogenic biofilm sample collected in 2009 in the Saint Callixstus Roman catacomb. The strain was found to belong to the genus Kribbella by analysis of the 16S rRNA gene. Phylogenetic analysis using the 16S rRNA gene and the gyrB, rpoB, relA, recA and atpD concatenated gene sequences showed that strain BC637(T) was most closely related to the type strains of Kribbella lupini and Kribbella endophytica. DNA-DNA hybridization experiments confirmed that strain BC637(T) is a genomic species that is distinct from its closest phylogenetic relatives, K. endophytica DSM 23718(T) (63 % DNA relatedness) and K. lupini LU14(T) (63 % DNA relatedness). Physiological comparisons showed that strain BC637(T) is phenotypically distinct from the type strains of K. endophytica and K. lupini. Thus, strain BC637(T) represents the type strain of a novel species, for which the name Kribella italica sp. nov. is proposed ( = DSM 28967(T) = NRRL B-59155(T)).

Description of gamma radiation-resistant Geodermatophilus dictyosporus sp. nov. to accommodate the not validly named Geodermatophilus obscurus subsp. dictyosporus (Luedemann, 1968).
A gamma radiation-resistant, Gram reaction-positive, aerobic and chemoorganotrophic actinobacterium, initially designated Geodermatophilus obscurus subsp. dictyosporus G-5(T), was not validly named at the time of initial publication (1968). G-5(T) formed black-colored colonies on GYM agar. The optimal growth range was 25-35 °C, at pH 6.5-9.5 and in the absence of NaCl. Chemotaxonomic and molecular characteristics of the isolate matched those described for members of the genus Geodermatophilus. The DNA G + C content of the strain was 75.3 mol%. The peptidoglycan contained meso-diaminopimelic acid as diagnostic diamino acid. The main polar lipids were phosphatidylcholine, diphosphatidylglycerol, phosphatidylinositol, phosphatidylethanolamine and one unspecified glycolipid; MK-9(H4) was the dominant menaquinone and galactose was detected as a diagnostic sugar. The major cellular fatty acids were branched-chain saturated acids, iso-C16:0 and iso-C15:0. The 16S rRNA gene showed 94.8-98.4 % sequence identity with the members of the genus Geodermatophilus. Based on phenotypic results and 16S rRNA gene sequence analysis, strain G-5(T) is proposed to represent a novel species, Geodermatophilus dictyosporus and the type strain is G-5(T) (=DSM 43161(T) = CCUG 62970(T) = MTCC 11558(T) = ATCC 25080(T) = CBS 234.69(T) = IFO 13317(T) = KCC A-0154(T) = NBRC 13317(T)).

Actinokineospora spheciospongiae sp. nov., isolated from the marine sponge Spheciospongia vagabunda.
A Gram-staining-positive, aerobic organism, isolated from the Red Sea sponge Spheciospongia vagabunda was investigated to determine its taxonomic position. On the basis of results of 16S rRNA gene sequence analysis strain EG49(T) was most closely related to Actinokineospora cibodasensis and Actinokineospora baliensis (both 97.3 % similarity) and Actinokineospora diospyrosa and Actinokineospora auranticolor (both 97.0 % similarity). The 16S rRNA gene sequence similarity to all other species of the genus Actinokineospora was <97.0 %. The quinone system of strain EG49(T) contained the menaquinones MK-9(H4) (47 %), MK-9(H6) (27 %) and MK-9(H2) (15 %) in major amounts. Minor amounts of MK-7(H4) (2 %), MK-9(H0) (1 %), MK-9(H8) (3 %) and MK-10(H4) (3 %) were detected as well in addition to MK-8(H4), MK-8(H6), MK-10(H2) and MK-10(H6) (all <1 %). The diagnostic diamino acid of the peptidoglycan was meso-diaminopimelic acid. In the polar lipid profile, diphosphatidylglycerol, phosphatidylethanolamine and hydroxyphosphatidylethanolamine were predominant. Phosphatidylinositol-mannoside, two unidentified phospholipids and two glycoglipids as well as one aminoglycolipid, one aminolipid and one unidentified lipid were found in addition. The fatty acid profile was composed of mainly iso-branched fatty acids: iso-C16 : 0, iso-C14 : 0, iso-C15 : 0 and iso-C16 : 1H. All these findings clearly supported the classification of the strain as representing a member of the genus Actinokineospora. In addition, the results of physiological and biochemical tests also allowed phenotypic differentiation of strain EG49(T) from the most closely related species of the genus Actinokineospora. Strain EG49(T) represents a novel species of the genus Actinokineospora, for which we propose the name Actinokineospora spheciospongiae sp. nov., with strain EG49(T) ( = DSM 45935(T) = CCM 8480(T) = LMG 27700(T)) as the type strain.

A novel endophytic actinobacterium, designated EGI 6500707(T), was isolated from the surface-sterilized root of a halophyte Anabasis elatior (C. A. Mey.) Schischk collected from Urumqi, Xinjiang province, north-west China, and characterized using a polyphasic approach. Cells were Gram-stain-positive, non-motile, short rods and produced white colonies. Growth occurred at 10-45 °C (optimum 25-30 °C), at pH 5-10 (optimum pH 8) and in presence of 0-4% (w/v) NaCl (optimum 0-3%). The predominant menaquinone was MK-9. The diagnostic phospholipids were diphosphatidylglycerol and phosphatidylglycerol. The major fatty acids were anteiso-C(15 : 0), anteiso-C(17 : 0) and iso-C(16 : 0). The DNA G+C content of strain EGI 6500707(T) was 69.1 mol%. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain EGI 6500707(T) should be placed in the genus Frigoribacterium (family Microbacteriaceae , phylum Actinobacteria ), and that the novel strain exhibited the highest 16S rRNA gene sequence similarity to Frigoribacterium faeni JCM 11265(T) (99.1%) and Frigoribacterium mesophilum MSL-08(T) (96.5%). DNA-DNA relatedness between strain EGI 6500707(T) and F. faeni JCM 11265(T) was 47.2%. On the basis of phenotypic and chemotaxonomic characteristics, phylogenetic analysis and DNA-DNA relatedness data, strain EGI 6500707(T) represents a novel species of the genus Frigoribacterium , for which the name Frigoribacterium endophyticum sp. nov. is proposed.

Microbispora bryophytorum sp. nov., an actinomycete isolated from moss (Bryophyta).
A novel endophytic actinomycete, designated strain NEAU-TX2-2(T), was isolated from moss and characterized using a polyphasic approach. The isolate was found to have morphological characteristics typical of the genus Microbispora . The isolate formed longitudinally paired spores on the tips of short sporophores that branched from aerial hyphae. Analysis of the 16S rRNA gene sequence supported the assignment of the novel strain to the genus Microbispora , and strain NEAU-TX2-2(T) exhibited 99.08 and 98.62% gene sequence similarities to Microbispora amethystogenes JCM 3021(T) and Microbispora rosea subsp. rosea JCM 3006(T), respectively. However two tree-making algorithms supported the position that strain NEAU-TX2-2(T) formed a distinct clade with M. rosea subsp. rosea JCM 3006(T). A low level of DNA-DNA relatedness allowed the isolate to be differentiated from M. amethystogenes JCM 3021(T) and M. rosea subsp. rosea JCM 3006(T). Moreover, strain NEAU-TX2-2(T) could also be distinguished from its closest phylogenetic relatives by morphological and physiological characteristics. Therefore, it is proposed that strain NEAU-TX2-2(T) represents a novel species of the genus Microbispora for which the name Microbispora bryophytorum sp. nov. is proposed. The type strain is NEAU-TX2-2(T) ( = CGMCC 4.7138(T) = DSM 46710(T)).

Nonomuraea syzygii sp. nov., an endophytic actinomycete isolated from the roots of a jambolan plum tree (Syzygium cumini L. Skeels).
A novel endophytic actinomycete, designated strain GKU 164(T), was isolated from the roots of a jambolan plum tree (Syzygium cumini L. Skeels), collected at Khao Khitchakut National Park, Chantaburi province, Thailand. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the strain formed a distinct clade within the genus Nonomuraea , and was most closely related to Nonomuraea monospora PT708(T) (98.77% 16S rRNA gene sequence similarity) and Nonomuraea thailandensis KC-061(T) (98.73%). Strain GKU 164(T) formed a branched substrate and aerial hyphae that generated single spores with rough surfaces. The cell wall contained meso-diaminopimelic acid. The whole-cell sugars were madurose, galactose, mannose, ribose, rhamnose and glucose. The N-acyl type of muramic acid was acetyl. The predominant menaquinone was MK-9(H4) with minor amounts of MK-9(H6), MK-9(H2) and MK-9(H0). The phospholipid profile contained diphosphatidylglycerol, phosphatidylethanolamine, hydroxy-phosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositolmannosides, phosphatidylmonomethylethanolamine, hydroxy-phosphatidylmonomethylethanolamine, an unidentified aminophosphoglycolipid and four unknown phospholipids. The major fatty acids were iso-C(16 : 0) and 10-methyl C(17 : 0). The genomic DNA G+C content was 70.4 mol%. Significant differences in the morphological, chemotaxonomical, and biochemical data together with DNA-DNA relatedness values between strain GKU 164(T) and type strains of closely related species, clearly demonstrated that strain GKU 164(T) represents a novel species of the genus Nonomuraea , for which the name Nonomuraea syzygii sp. nov. is proposed.

Saccharothrix tamanrassetensis sp. nov., an actinomycete isolated from Saharan soil.
Actinomycete strain SA198(T), isolated from a Saharan soil sample of Algeria, was characterized taxonomically by using a polyphasic approach. Chemotaxonomic and morphological characteristics observed suggested that it was a member of the genus Saccharothrix . The 16S rRNA gene sequence analysis confirmed that strain SA198(T) was a member of the genus Saccharothrix and showed a similarity level ranging between 97.5 and 98.9% within species of the genus Saccharothrix , Saccharothrix australiensis being the most closely related. However, DNA-DNA hybridization values between strain SA198(T) and its closest phylogenetic neighbours, the type strains of S. australiensis , Saccharothrix xinjiangensis , Saccharothrix algeriensis and Saccharothrix espanaensis , were clearly below the 70% threshold. Based upon genotypic and phenotypic differences from other members of the genus, a novel species, Saccharothrix tamanrassetensis sp. nov., is proposed, with SA198(T) ( = DSM 45947(T) = CECT 8640(T)) as the type strain.

Parabacteroides faecis sp. nov., isolated from human faeces.
A bacterial strain, designated 157(T), isolated from human faeces was characterized by using a polyphasic taxonomic approach, which included analysis of physiological and biochemical features, cellular fatty acid profiles, menaquinone profiles and its phylogenetic position, based on 16S rRNA gene sequence analysis. The strain was obligately anaerobic, non-pigmented, non-spore-forming, non-motile, Gram-stain-negative rods. The isolate was able to grown on medium containing 20% (w/v) bile. 16S rRNA gene sequence analysis showed that the strain was a member of the genus Parabacteroides . Strain 157(T) was closely related to Parabacteroides gordonii JCM 15724(T) (96% sequence similarity). The results of hsp60 gene sequence analysis indicated that strain 157(T) was different from P. gordonii JCM 15724(T), with a hsp60 gene sequence similarity of 96.1%. The major cellular fatty acids of strain 157(T) were anteiso-C(15 : 0), iso-C(17 : 0) 3-OH, C(18 : 1)ω9c and anteiso-C(17 : 0) 3-OH. The major menaquinone of the isolate was MK-9. The DNA G+C content of strain 157(T) was 41.8 mol%. On the basis of these data, strain 157(T) represents a novel species of the genus Parabacteroides , for which the name Parabacteroides faecis sp. nov. is proposed; the type strain is 157(T) ( = JCM 18682(T) = CCUG 66681(T)).

Myceligenerans cantabricum sp. nov., a barotolerant actinobacterium isolated from a deep cold-water coral.
An actinobacterium strain (M-201(T)) was isolated from a deep-sea scleractinian coral (Fam. Caryophillidae) collected at 1500 m depth in the Avilés Canyon in the Cantabrian Sea, Asturias, Spain. Strain M-201(T) grew at pH 6.0-9.0 (optimum pH 7.0), between 4 and 37 °C (optimum 28 °C) and at salinities of 0.5-10.5% (w/v) NaCl (optimum 0.5-3.0%). The peptidoglycan contained the amino acids Lys, Ala, Thr, Glu and one unknown amino acid component, and belonged to type A4α, and the cell-wall sugars are glucose, mannose and galactose. The polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, an unknown phosphoglycolipid and seven unknown glycolipids. The predominant menaquinones were MK-9(H4) and MK-9(H6). Major cellular fatty acids were anteiso-C(15 : 0), iso-C(15 : 0) and anteiso-C(17 : 0). The genomic DNA G+C content was 72.4 mol%. The chemotaxonomic properties supported the affiliation of strain M-201(T) to the genus Myceligenerans . Phylogenetic analysis based on 16S rRNA gene sequences revealed that the organism was most closely related to Myceligenerans crystallogenes CD12E2-27(T) (98.2% 16S rRNA gene sequence similarity). However, it had a relatively low DNA-DNA relatedness value with the above strain (48%). The isolate showed antibiotic activity against Escherichia coli , Micrococcus luteus ATCC 14452 and Saccharomyces cerevisiae var. carlsbergensis. To the best of our knowledge, this is the first report of antibiotic production in the genus Myceligenerans . The differences in phenotypic, metabolic, ecological and phylogenetic characteristics justify the proposal of a novel species of the genus Myceligenerans , Myceligenerans cantabricum sp. nov., with M-201(T) ( = CECT 8512(T) = DSM 28392(T)) as the type strain.

Corynebacterium pelargi sp. nov., isolated from the trachea of white stork nestlings.
A Gram-stain-positive, pleomorphic, oxidase-negative, non-motile isolate from the trachea of a white stork from Poland, designated strain 136/3(T), was subjected to a comprehensive taxonomic investigation. A comparative analysis of the 16S rRNA gene sequence showed highest similarities to Corynebacterium mustelae , Corynebacterium pseudotuberculosis , Corynebacterium vitaeruminis and Corynebacterium ulcerans (96.0-96.3%). The quinone system consisted of major amounts of MK-8(H2), minor amounts of MK-9(H2) and traces of MK-8 and MK-9. The polar lipid profile of strain 136/3(T) contained phosphatidylinositol and phosphatidylinositol-mannoside as major lipids and phosphatidylglycerol and an acidic glycolipid in moderate amounts. In addition small amounts of diphosphatidylglycerol, a phospholipid, an aminolipid and two lipids of unknown group affiliation were found. The polyamine pattern was composed of the major components spermidine and spermine. Putrescine, 1,3-diaminopropane, cadaverine, sym-homospermidine and tyramine were found in minor or trace amounts. The diamino acid of the peptidoglycan was meso-diaminopimelic acid. In the fatty acid profile straight-chain, saturated and mono-unsaturated fatty acids predominated (C(18 : 1)ω9c, C(16 : 1)ω7c, C16 : 0, C(18 : 0)). Corynemycolic acids were detected. Physiological traits as well as unique traits of the polar lipid profile and the fatty acid pattern distinguished strain 136/3(T) from the most closely related species. All these results indicate that strain 136/3(T) represents a novel species of the genus Corynebacterium for which we propose the name Corynebacterium pelargi sp. nov. The type strain is 136/3(T) ( =CIP 110778(T) =CCM 8517(T) =LMG 28174(T)).

Actinomadura darangshiensis sp. nov., isolated from a volcanic cone.
An actinobacterium, designated strain DLS-70(T), was isolated from a soil sample from the surface of a rock on the peak of Darangshi Oreum (a volcanic cone) in Jeju, Republic of Korea. Substrate mycelium was produced abundantly on most of the media tested. Spiral chains of spores with warty surface developed on the aerial hyphae. A phylogenetic tree based on 16S rRNA gene sequences showed that strain DLS-70(T) belonged to the genus Actinomadura and was most closely related to Actinomadura bangladeshensis DSM 45347(T) (98.9% sequence similarity), Actinomadura madurae DSM 43067(T) (98.8%) and Actinomadura chokoriensis DSM 45346(T) (98.6%). Chemotaxonomic observations supported the assignment of the isolate to the genus Actinomadura . DNA-DNA relatedness values between strain DLS-70(T) and the type strains of the closest phylogenetic relatives were less than 20%. On the basis of data from this polyphasic study, strain DLS-70(T) ( =KCTC 29224(T) =DSM 45941(T)) is considered to represent a novel species of the genus Actinomadura , for which the name Actinomadura darangshiensis sp. nov. is proposed.

Streptomyces albiflavescens sp. nov., an actinomycete isolated from soil.
Two actinobacterial strains, m20(T) and z8, were isolated from soil taken from rainforest areas/tropic forest region, Yunnan Province, south-west China. The 16S rRNA gene sequence similarities and DNA-DNA relatedness values between strains m20(T) and z8 were 100 and 88.2%, respectively, which indicated that these two strains should be classified as the same species. The taxonomic position of the strains was determined by a polyphasic approach. Morphological and chemotaxonomic features of the strains were consistent with those of the genus Streptomyces . A phylogenetic tree based on 16S rRNA gene sequences showed that strains m20(T) and z8 formed an evolutionary branch within the genus Streptomyces and shared relatively high 16S rRNA gene sequence similarity values with other members of this genus, including 'Streptomyces siamensis' NBRC 108799 (98.95%), Streptomyces graminilatus NBRC 108882(T) (98.25%), Streptomyces seoulensis NBRC 16668(T) (98.11%), Streptomyces peucetius ATCC 29050(T) (98.11%) and Streptomyces hygroscopicus subsp. ossamyceticus ATCC 15420(T) (98.11%). DNA-DNA relatedness values between strain m20(T) and the five above-mentioned strains were 56.3, 55.1, 52.8, 50.1 and 48.4%, respectively. On the basis of phenotypic, genotypic and phylogenetic properties, strains m20(T) and z8 could be distinguished from phylogenetically related members of the genus Streptomyces . The isolates thus merit species status within the genus Streptomyces , for which the name http://dx.doi.org/10.1601/nm.6817 Streptomyces albiflavescens sp. nov. is proposed. The type strain is m20(T) ( =CGMCC 4.7111(T) =KCTC 29196(T)). Strain z8 ( =CGMCC 4.7112=KCTC 29197) is a reference strain.

Prauserella isguenensis sp. nov., a halophilic actinomycete isolated from desert soil.
Two actinomycete strains, designated H225(T) and H137, were isolated from two soil samples collected from the arid region of Ahbas at Béni-Isguen (Mzab), located in the Algerian Sahara. Phylogenetic analyses based on 16S rRNA gene sequences indicated that the novel strains should be assigned to the genus Prauserella of the family Pseudonocardiaceae , and they were therefore subjected to a polyphasic taxonomic study. These two strains contained meso-diaminopimelic acid as the diagnostic diamino acid and arabinose and galactose as major whole-cell sugars. The diagnostic phospholipid was phosphatidylethanolamine. The predominant menaquinone was MK-9(H4), and the major fatty acid was iso-C16 : 0. DNA-DNA hybridization values between strain H225(T) and its closest phylogenetic neighbours, namely Prauserella flava DSM 45265(T), Prauserella alba DSM 44590(T), Prauserella aidingensis DSM 45266(T), Prauserella salsuginis DSM 45264(T) and Prauserella sediminis DSM 45267(T), were clearly below the 70% threshold used for species delineation. The genomic DNA G+C content of strains H225(T) and H137 was 70.4 mol%. On the basis of phenotypic and genotypic data, strains H225(T) and H137(T) are considered to represent a novel species of the genus Prauserella , for which the name Prauserella isguenensis sp. nov. is proposed. The type strain is H225(T) ( =DSM 46664(T) = CECT 8577(T)).

Jatrophihabitans soli sp. nov., isolated from soil.
One bacterial strain, designated KIS75-12T, isolated from a soil sample collected from Wonsando island located in Boryeong city, Republic of Korea, was characterized as aerobic, Gram-stain-positive, non-flagellated and a short rod. It grew between temperatures of 15-37 °C, pH 4-9 and 0-3.0 % (w/v) NaCl. The 16S rRNA gene analysis showed the strain was moderately related to Jatrophihabitans endophyticus S9-650T (97.7 %) and revealed low sequence similarity (≤94.7 %) with all the other species with validly published names. Its major fatty acid was iso-C16 : 0. The predominant menaquinone of strain KIS75-12T was MK-9(H4). The polar lipids consisted of diphosphatidylglycerol and several small amounts of phosphatidylinositol, aminolipids and glycolipid. The peptidoglycan contained meso-A2pm as diagnostic diamino acid and the peptidoglycan type is A4γ. The genomic DNA G+C content of the type strain was 72.1 mol%. The combined phenotypic, chemotaxonomic and phylogenetic data showed that strain KIS75-12T could be clearly distinguished from the only member of the genus Jatrophihabitans,J. endophyticus. Therefore, the results of this study indicate the existence of a representative of a novel species of the genus Jatrophihabitans, for which we propose the name Jatrophihabitans soli sp. nov., with strain KIS75-12T ( = KACC 17298T = DSM 45908T = NBRC 109658T) as the type strain.

The DNA-DNA relatedness values were 21.8-27 % with S. siamense A-T 1946T and 31.1-31.9 % with S. album 6014T, which were significantly below 70 %. The result differentiated A-T 8343T from the closest species. The organism developed spherical sporangia containing non-motile spores on aerial mycelia. The cell-wall peptidoglycan contained meso-diaminopimelic acid. The whole-cell sugars contained rhamnose, ribose, madurose and glucose. The predominant menaquinones were MK-9(H2) and MK-9(H4). The diagnostic phospholipids were phosphatidylmethylethanolamine, phosphatidylethanolamine, hydroxyl-phosphatidylethanolamine, diphosphatidylglycerol, lyso-phosphatidylethanolamine, N-acetylglucosamine-containing phospholipids, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol-mannosides, aminophosphoglycolipid and one unknown phospholipid. The major cellular fatty acids were saturated C16 : 0, iso C16 : 0, unsaturated C16 : 1 and C18 : 1. Following an evaluation of phenotypic, chemotaxonomic and genotypic characteristics, the new isolate is proposed as a representative novel species of the genus Sinosporangium to be named Sinosporangiumfuscum sp. nov.

A bacterial strain named BSTT44(T) was isolated in the course of a study of endophytic bacteria occurring in stems and roots of potato growing in a soil from Salamanca, Spain. The 16S rRNA gene sequence had 99.7% identity with respect to that of its closest relative, Pseudomonas psychrophila E-3T, and the next most closely related type strains were those of Pseudomonas fragi, with 99.6% similarity, Pseudomonas deceptionensis, with 99.2% similarity, and Pseudomonas lundensis, with 99.0% similarity; these results indicate that BSTT44(T) should be classified within the genus Pseudomonas. Analysis of the housekeeping genes rpoB, rpoD and gyrB confirmed its phylogenetic affiliation and showed identities lower than 92% in all cases with respect to the above-mentioned closest relatives. Cells of the strain bore one polar-subpolar flagellum. The respiratory quinone was Q-9.The major fatty acids were C16:0, C18:1ω7c and summed feature 3 (C16:1ω7c and/or C16:1ω6c).

Emended description of Actinoplanes friuliensis and description of Actinoplanes nipponensis sp. nov., antibiotic-producing species of the genus Actinoplanes.
In 2000, an actinomycete strain that showed strong antibacterial activity in culture extracts was isolated from a soil sample. The antibiotic activity corresponds to a lipopeptide complex that was named friulimycin, as the producing micro-organism was isolated from a soil sample from the region of Friaul in Italy. Taxonomic investigations showed that the producer strain belonged to a novel species of the genus Actinoplanes, for which the name Actinoplanes friuliensis was proposed. During further taxonomic studies, another antibiotic-producing isolate belonging to the genus Actinoplanes, FH 2241(T), was characterized; in a patent, the name 'Actinoplanes nipponensis' was proposed for this strain. This organism was shown to be related to A. friuliensis. 'A. nipponensis' was never described in detail and the name was never validly published. Here we present a complete description of Actinoplanes nipponensis sp. Nov. (type strain FH 2241(T) = ATCC 31145(T) = DSM 43867(T)) and an emended description of Actinoplanes friuliensis (type strain HAG 010964(T) = DSM 45797(T) = CCUG 63250(T)).

Strain K413(T) was most closely related to Streptomyces marinus DSM 41968(T) (98.01%). Sequence similarities with other strains of the genus Streptomyces were below 98.0%. The cell wall of the novel strain contained ll-diaminopimelic acid. The predominant menaquinone was MK-9(H8) (45.0%). The polar lipids detected were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylmonomethylethanolamine and phosphatidylinositol. The major fatty acids were anteiso-C15:0, iso-C16:0 and anteiso-C17:0. Based on 16S rRNA gene sequence analysis, DNA-DNA relatedness, phenotypic characteristics and chemotaxonomic data, strain K413(T) represents a novel species of the genus Streptomyces, for which the name Streptomyces karpasiensis sp. nov. is proposed. The type strain is K413(T) ( = KCTC 29096(T) = DSM 42068(T)).

Saccharopolyspora ghardaiensis sp. nov., an extremely halophilic actinomycete isolated from Algerian Saharan soil.
A novel halophilic actinomycete, strain designated H53(T), was isolated from a Saharan soil sample collected from Chaâbet Ntissa, Béni-isguen, Ghardaïa (South of Algeria) and was characterized taxonomically by means of polyphasic approach. Optimal growth was found to occur at 30-35 °C, pH 6-7 and in the presence of 15-25% (w/v) NaCl. The strain was observed to produce abundant aerial mycelium, which formed long chains of rod-shaped spores at maturity, and well developed and fragmented substrate mycelium. The cell wall was determined to contain meso-diaminopimelic acid; the diagnostic whole-cell sugars were arabinose and galactose. The predominant menaquinones were found to be MK-9(H₄) and MK-9(H₆). The predominant cellular fatty acids were determined to be iso- and anteiso-C17:0, iso-C15:0, and cis9 iso-C17:1. The diagnostic phospholipid detected was phosphatidylcholine. The morphological and chemotaxonomic characteristics of the strain were consistent with those of members of the genus Saccharopolyspora. Phylogenetic analyses on the basis of the 16S ribosomal RNA (rRNA) gene sequence showed that this strain formed a distinct phyletic line within the radiation of the genus Saccharopolyspora. The 16S rRNA sequence similarities between strain H53(T) and other members of the genus Saccharopolyspora ranged from 92.1 to 94.3%. The DNA G+C content of strain H53(T) was 72.6%. The genotypic and phenotypic data showed that the strain H53(T) represents a novel species of the genus Saccharopolyspora, for which the name Saccharopolyspora ghardaiensis sp. nov. is proposed, with the type strain H53(T) (=DSM 45606(T)=CCUG 63370(T)=CECT 8304(T)).

Mariniluteicoccus flavus gen. nov., sp. nov., a new member of the family Propionibacteriaceae, isolated from a deep-sea sediment.
A Gram-staining-positive, aerobic, non-motile, irregular coccus, designated strain YIM M13146(T), was isolated from a sediment sample collected from the South China Sea at a depth of 2439 m, and its taxonomic position was determined by a polyphasic approach. Optimal growth of the strain was observed at 30 °C (range 5-40 °C), pH 7.0 (pH 6.0-9.0) and 0-1% NaCl (0-6%, w/v) on/in tryptic soy agar/broth. Strain YIM M13146(T) had the major cellular fatty acid anteiso-C15:0, the predominant respiratory menaquinone MK-9(H4), peptidoglycan type A3γ (ll-DAP-Gly) containing alanine, glycine, glutamic acid and ll-diaminopimelic acid (ll-DAP) and the polar lipids phosphatidylcholine, diphosphatidylglycerol, one unknown phospholipid and several glycolipids. The G+C content of the DNA was 67.2 mol%. Phenotypic and chemotaxonomic characteristics together with 16S rRNA gene sequence analyses showed that strain YIM M13146(T) was distinct from its close phylogenetic relatives in the genera Propioniferax and Granulicoccus of the family Propionibacteriaceae. Hence, a new genus and species, Mariniluteicoccus flavus gen. nov., sp. nov., is proposed. The type strain of Mariniluteicoccus flavus is YIM M13146(T) ( = DSM 25892(T) = CCTCC AB 2012055(T)).

An endophytic actinomycete, strain R10-82(T), isolated from surface-sterilized roots of rice (Oryza sativa L.) was studied using a polyphasic approach. Strain R10-82(T) produced branching substrate mycelia and developed spherical spore vesicles on aerial hyphae containing non-motile spores. The major cellular fatty acids were iso-C16 : 0, iso-C14 : 0 and 10-methyl C17 : 0. The predominant menaquinones were MK-9, MK-9(H2), MK-9(H4) and MK-9(H6). Rhamnose, ribose, madurose, mannose and glucose were detected in whole-cell hydrolysates. The diagnostic phospholipids were phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylinositol mannosides, hydroxylphosphatidylethanolamine and ninhydrin-positive phosphoglycolipids. These morphological and chemotaxonomic data were similar to those of the genus Sphaerisporangium. Analysis of the 16S rRNA gene sequence revealed that strain R10-82(T) was related most closely to Sphaerisporangium cinnabarinum JCM 3291(T) (98.3 % similarity). The DNA G+C content of strain R10-82(T) was 74 mol%. DNA-DNA relatedness data in combination with differences in the biochemical and physiological properties suggested that strain R10-82(T) should be classified as representing a novel species of the genus Sphaerisporangium, for which the name Sphaerisporangium rufum is proposed. The type strain is R10-82(T) ( = BCC 51287(T) = NBRC 109079(T)). An emended description of the genus Sphaerisporangium is also provided.

Streptomyces zhaozhouensis sp. nov., an actinomycete isolated from candelabra aloe (Aloe arborescens Mill).
A novel endophytic actinomycete, designated strain NEAU-LZS-5(T), was isolated from the leaf of candelabra aloe (Aloe arborescens Mill) and characterized using a polyphasic approach. Analysis of the 16S rRNA gene sequence showed that strain NEAU-LZS-5(T) belongs to the genus Streptomyces and exhibited 99.51 and 97.37 % similarity to Streptomyces sedi YIM 65188(T) and Streptomyces specialis GW41-1564(T), respectively, whereas low similarity values (<97 %) distinguished strain NEAU-LZS-5(T) from all other species of the genus Streptomyces with validly published names. Two tree-making algorithms also supported the position that strain NEAU-LZS-5(T) formed a distinct clade with Streptomyces sedi YIM 65188(T) and Streptomyces specialis GW41-1564(T). However, levels of DNA-DNA relatedness between strain NEAU-LZS-5(T) and Streptomyces sedi YIM 65188(T) and Streptomyces specialis GW41-1564(T) were 45.59 and 31.90 %, respectively. A comparative study between strain NEAU-LZS-5(T) and the type strains of closest related species of the genus Streptomyces revealed that it differed from them in morphological, physiological and biochemical characteristics. Therefore, strain NEAU-LZS-5(T) represents a novel species of the genus Streptomyces, for which the name Streptomyces zhaozhouensis sp. nov. is proposed. The type strain is NEAU-LZS-5(T) ( = CGMCC 4.7095(T) = DSM 42101(T)).

Nonomuraea fuscirosea sp. nov., an actinomycete isolated from the rhizosphere soil of rehmannia (Rehmannia glutinosa Libosch).
A novel actinomycete, designated strain NEAU-dht8(T), was isolated from the rhizosphere soil of rehmannia (Rehmannia glutinosa Libosch) and characterized using a polyphasic approach. The organism was found to have morphological and chemotaxonomic characteristics typical of the genus Nonomuraea. The G+C content of the DNA was 68.47 mol%. On the basis of 16S rRNA gene sequence similarity studies, strain NEAU-dht8(T) was most closely related to Nonomuraea maheshkhaliensis 16-5-14(T) (99.31%), Nonomuraea kuesteri GW 14-1925(T) (98.77%), Nonomuraea coxensis JCM 13931(T) (98.71%), Nonomuraea wenchangensis 210417(T) (98.44 %), Nonomuraea bangladeshensis 5-10-10(T) (98.36%) and Nonomuraea salmonea DSM 43678(T) (98.0%); similarities to other species of the genus Nonomuraea were lower than 98%. Two tree-making algorithms based on 16S rRNA gene sequences showed that the isolate formed a phyletic line with its closest neighbour N. maheshkhaliensis 16-5-14(T). However, the low level of DNA-DNA relatedness allowed the novel isolate to be differentiated from N. maheshkhaliensis 16-5-14(T). Strain NEAU-dht8(T) could also be differentiated from other species of the genus Nonomuraea showing high 16S rRNA gene sequence similarity (98-98.77%) by morphological and physiological characteristics. Thus, strain NEAU-dht8(T) is considered to represent a novel species of the genus Nonomuraea, for which the name Nonomuraea fuscirosea sp. nov. is proposed.

The G+C content of the genomic DNA was 70.7 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain Chem10(T) belonged to the family Pseudonocardiaceae and showed the closest phylogenetic similarity to Alloactinosynnema album KCTC 19294(T) (98.3 %) and Actinokineospora cibodasensis DSM 45658(T) (97.9 %). DNA-DNA relatedness values between the novel strain and strains Alloactinosynnema album KCTC 19294(T) and Actinokineospora cibodasensis DSM 45658(T) were only 52 % and 23 %, respectively.

Planobispora takensis sp. nov., isolated from soil.
A novel Gram-stain-positive, filamentous bacterial strain (A-T 7458(T)) was isolated from soil collected from hill evergreen forest in Thailand. The strain developed cylindrical sporangia containing a longitudinal pair of motile spores, on short ramifications of aerial mycelia. From a taxonomic study using a polyphasic approach, strain A-T 7458(T) had typical characteristics of members of the genus Planobispora. 16S rRNA gene sequence analysis indicated that the isolate was closely related to Planobispora siamensis A-T 4600(T) (98.5 %), Planobispora rosea JCM 3166(T) (97.6 %) and Planobispora longispora NBRC 13918(T) (97.6 %). The DNA-DNA relatedness values, which differentiated the novel strain from the closest species, were significantly below 70 %. The cell-wall peptidoglycan contained meso-diaminopimelic acid. The whole-cell sugars contained ribose, madurose, mannose and glucose. The predominant menaquinone was MK-9(H2). The diagnostic phospholipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylmethylethanolamine, phosphatidylinositol, phosphatidylinositol-mannoside and aminophosphoglycolipid. The predominant cellular fatty acids were unsaturated C17 : 1 and C18 : 1, and saturated C16 : 0 and C17 : 0. Following an evaluation of phenotypic, chemotaxonomic and genotypic characteristics, the novel isolate is proposed to represent a novel species of the genus Planobispora, to be named Planobispora takensis sp. nov.

Streptomyces barkulensis sp. nov., isolated from an estuarine lake.
The taxonomic position of a novel actinomycete, strain RC 1831(T), isolated from the sediment of a fish dumping yard at Barkul village near Chilika Lake, Odisha, India, was determined by a polyphasic approach. Based on morphological and chemotaxonomic characteristics the isolate was determined to belong to the genus Streptomyces. The phylogenetic tree based on its nearly complete 16S rRNA gene sequence (1428 nt) with representative strains showed that the strain consistently falls into a distinct phyletic line together with Streptomyces glaucosporus DSM 41689(T) (98.22% similarity) and a subclade consisting of Streptomyces atacamensis DSM 42065(T) (98.40%), Streptomyces radiopugnans R97 DSM 41901(T) (98.27%), Streptomyces fenghuangensis GIMN4.003(T) (98.33 %), Streptomyces nanhaiensis DSM 41926(T) (98.13%), Streptomyces megasporus NBRC 14749(T) (97.37%) and Streptomyces macrosporus NBRC 14748(T) (98.22%). However, the levels of DNA-DNA relatedness between strain RC 1831(T) and phylogenetically related strains Streptomyces atacamensis DSM 42065(T) (28.75 ± 3.25%) and Streptomyces glaucosporus DSM 41689(T) (15 ± 2.40%) were significantly lower than the 70% threshold value for delineation of genomic species. Furthermore, the isolate could be distinguished phenotypically on the basis of physiological, morphological and biochemical differences from its closest phylogenetic neighbours and other related reference strains. Strain RC 1831(T) is therefore considered to represent a novel species of the genus Streptomyces, for which the name Streptomyces barkulensis sp. nov. is proposed. The type strain is RC 1831(T) ( = JCM 18754(T) = DSM 42082(T)).

Streptomyces catbensis sp. nov., isolated from soil.
Strain VN07A0015(T) was isolated from soil collected on Cat Ba Island, Vietnam. The taxonomic position of strain VN07A0015(T) was near Streptomyces aomiensis M24DS4(T) (98.5% 16S rRNA gene sequence similarity) and Streptomyces scabrisporus NBRC 100760(T) (95.6%), and it clustered within them; however, this cluster was distant from the type strains of other species of the genus Streptomyces. The aerial mycelia of strain VN07A0015(T) were greyish and formed imperfect spiral spore chains (retinaculiaperti type) with smooth-surfaced spores. The morphological features of strain VN07A0015(T) were different from those of the type strains of S. aomiensis and S. scabrisporus. The chemotaxonomic characteristics of strain VN07A0015(T) were typical for all members of the genus Streptomyces, which possessed ll-type diaminopimelic acid, menaquinone MK-9(H6, H8) and the major fatty acids iso-C(16 : 0) and iso-C(15 : 0). DNA-DNA relatedness between strain VN07A0015(T) and S. aomiensis NBRC 106164(T) was less than 30%. In addition, some physiological and biochemical traits differed from those of S. aomiensis. Therefore, we propose that strain VN07A0015(T) be classified in the genus Streptomyces as a representative of Streptomyces catbensis sp. nov. (type strain VN07A0015(T) = VTCC-A-1889(T) = NBRC 107860(T)).

A Gram-staining-positive, aerobic, non-spore-forming, irregular rod-shaped actinobacterium, designated YIM C00895(T), was isolated from a soil sample collected from Jiuxiang Scenic Region, Yunnan province, south-west China. The strain was able to grow at 10-28 °C, pH 6.0-10.0 and 0-11% NaCl (w/v). Phylogenetic analysis based on 16S rRNA (95.3%) gene sequences revealed the highest similarity to Tomitella biformata AHU1821(T). The whole-cell hydrolysates of strain YIM C00895(T) contained meso-diaminopimelic acid, arabinose and galactose, indicating chemotype IV. The muramic acids in the peptidoglycan were glycolated. The polar lipids consisted of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol mannosides and an unidentified glycolipid. MK-9(H2) was the predominant menaquinone. The major fatty acids were C14 : 0, C16 : 0, C16 : 1 and C18 : 1ω9c and tuberculostearic acid (10-methyl C18 : 0) was present in relatively small amounts (4.5%). TLC analysis of its cellular mycolic acids showed a similar profile to Tomitella biformata DSM 45403(T). The DNA G+C content of the strain was 67.5 mol%. The results of physiological and biochemical tests allowed strain YIM C00895(T) to be differentiated phenotypically from Tomitella biformata DSM 45403(T). On the basis of evidence from this polyphasic study, the novel species Tomitella cavernea sp. nov. is proposed.

The polar lipid profile of strain BNT558(T) contained diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, one unidentified glycolipid and one unidentified aminophospholipid, while that of strain SM3501(T) consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, phosphatidylethanolamine, three unidentified atypical aminolipids, one unidentified aminolipid and two unidentified glycolipids. The G+C contents of the genomic DNA were 70.2 and 69.6 mol% for strains BNT558(T) and SM3501(T), respectively. 16S rRNA gene sequence data supported the classification of the isolates in the genus Streptomyces and showed that they formed two distinct branches within the genus. Based on almost-complete 16S rRNA gene sequences, strain BNT558(T) was related most closely to Streptomyces albiaxialis NRRL B-24327(T) and strain SM3501(T) was related most closely to Streptomyces cacaoi subsp. cacaoi NBRC 12748(T). DNA-DNA relatedness between each of the isolates and its closest phylogenetic neighbours showed that they belonged to distinct species. The two isolates were readily distinguished from one another and from the type strains of the other species classified in the genus Streptomyces based on a combination of phenotypic and genotypic properties. Based on the genotypic and phenotypic evidence, strains BNT558(T) and SM3501(T) belong to two novel species in the genus Streptomyces, for which the names Streptomyces iconiensis sp. nov. (type strain BNT558(T) = KCTC 29198(T) = DSM 42109(T)) and Streptomyces smyrnaeus sp. nov. (type strain SM3501(T) = KCTC 29214(T) = DSM 42105(T)) are proposed, respectively.

Streptomyces pluripotens sp. nov., a bacteriocin-producing streptomycete that inhibits meticillin-resistant Staphylococcus aureus.
Two novel actinobacteria, strains MUSC 135(T) and MUSC 137, were isolated from mangrove soil at Tanjung Lumpur, Malaysia. The 16S rRNA gene sequence similarity and DNA-DNA relatedness between strains MUSC 135(T) and MUSC 137 were 100 % and 83±3.2 %, confirming that these two strains should be classified in the same species. Strain MUSC 135(T) exhibited a broad-spectrum bacteriocin against the pathogens meticillin-resistant Staphylococcus aureus (MRSA) strain ATCC BAA-44, Salmonella typhi ATCC 19430(T) and Aeromonas hydrophila ATCC 7966(T). A polyphasic approach was used to study the taxonomy of MUSC 135(T), and it showed a range of phylogenetic and chemotaxonomic properties consistent with those of the genus Streptomyces. The diamino acid of the cell-wall peptidoglycan was ll-diaminopimelic acid. The predominant menaquinones were MK-9(H6), MK-9(H4) and MK-9(H8). Polar lipids detected were a lipid, an aminolipid, a phospholipid, phosphatidylinositol, phosphatidylethanolamine and two glycolipids. The predominant cellular fatty acids (>10.0 %) were anteiso-C15 : 0 (20.8 %), iso-C16 : 0 (18.0 %), iso-C15 : 0 (12.2 %) and anteiso-C17 : 0 (11.6 %). The whole-cell sugars were ribose, glucose and mannose. These results suggested that MUSC 135(T) should be placed within the genus Streptomyces. Phylogenetic analysis based on the 16S rRNA gene sequence exhibited that the most closely related strains were Streptomyces cinereospinus NBRC 15397(T) (99.18 % similarity), Streptomyces mexicanus NBRC 100915(T) (99.17 %) and Streptomyces coeruleofuscus NBRC 12757(T) (98.97 %). DNA-DNA relatedness between MUSC 135(T) and closely related type strains ranged from 26.3±2.1 to 49.6±2.5 %. BOX-PCR fingerprint comparisons showed that MUSC 135(T) exhibited a unique DNA profile. The DNA G+C content determined was 70.7±0.3 mol%. Based on our polyphasic study of MUSC 135(T), the strain merits assignment to a novel species, for which the name Streptomyces pluripotens sp. nov. is proposed. The type strain is MUSC 135(T) ( = MCCC 1K00252(T) = DSM 42140(T)).

A Gram-stain-positive, aerobic, non-motile, non-spore-forming, cocci-shaped actinobacterium, designated strain EBR4-1-2(T), was isolated from a biofilm reactor in Korea. Comparative 16S rRNA gene sequence studies showed the isolate was clearly affiliated with the class Actinobacteria, and was related most closely to Flaviflexus huanghaiensis H5(T), showing 98.9 % similarity. Cells of strain EBR4-1-2(T) formed yellow colonies on R2A agar, contained MK-9(H4) as the predominant menaquinone, and included C18 : 1ω9c, C16 : 0, C16 : 1ω9c and C14 : 0 as the major fatty acids. The cell-wall peptidoglycan type was A5α (l-Lys-l-Ala-l-Lys-d-Glu). The G+C content of the genomic DNA of strain EBR4-1-2(T) was 65.6 mol%. Thus, the combined genotypic and phenotypic data supported the conclusion that strain EBR4-1-2(T) represents a novel species of the genus Flaviflexus, for which the name Flaviflexus salsibiostraticola sp. nov. is proposed. The type strain is EBR4-1-2(T) ( = KCTC 33148(T) = JCM 19016(T)).

Promicromonospora iranensis sp. nov., an actinobacterium isolated from rhizospheric soil.
A novel strain of the genus Promicromonospora, designated HM 792(T), was isolated from soil in Fars Province, Iran. On ISP 2 medium, the yellow-pigmented isolate produced long and branched hyphae that developed into a large number of irregularly shaped spores. It showed growth at 25-30 °C and pH 6.0-9.0 with 0-8 % (w/v) NaCl. Chemotaxonomic and molecular characteristics of the isolate matched those described for members of the genus Promicromonospora. Whole-cell hydrolysates of strain HM 792(T) contained the amino acids d-glutamic acid, l-alanine and l-lysine along with the sugars glucose and ribose. The main polar lipids were diphosphatidylglycerol, two unknown phospholipids, two unknown glycolipids and two unknown phosphoglycolipids, complemented by minor concentrations of phosphatidylinositol and phosphatidylglycerol. MK-9(H4) was the predominant menaquinone. The fatty-acid pattern was composed mainly of the saturated branched-chain acids anteiso-C15 : 0 and iso-C15 : 0. 16S rRNA gene sequence analysis showed the highest pairwise sequence identity (96.6-99.0 %) with the members of the genus Promicromonospora. Based on phenotypic and genotypic features, strain HM 792(T) is considered to represent a novel species of the genus Promicromonospora, for which the name Promicromonospora iranensis sp. nov. is proposed. Strain HM 792(T) ( = DSM 45554(T) = UTMC00792(T) = CCUG 63022(T)) is the type strain.

A novel Gram-stain-positive actinobacterium, designated strain SCSIO 11529(T), was isolated from tissues of the stony coral Galaxea fascicularis, and characterized by using a polyphasic approach. The temperature range for growth was 22-50 °C (optimum 28-45 °C), the pH range for growth was 6.0-8.0 (optimum pH 7.0), and the NaCl concentration range for growth was 0-7% (w/v) NaCl. The polar lipid profile contained diphosphatidylglycerol, phosphatidylcholine, phosphatidylglycerol, phosphatidylmethylethanolamine, phosphatidylethanolamine and an unknown polar lipid. The predominant menaquinone was MK-9(H4). The major fatty acids (>10%) were iso-C16:0, iso-C17:1ω6c, iso-C16:1 H and C16:1ω7c/iso-C15:0 2-OH. The DNA G+C content of strain SCSIO 11529(T) was 70.2 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain SCSIO 11529(T) belongs to the genus Prauserella, with the closest neighbours being Prauserella marina MS498(T) (97.0% 16S rRNA gene sequence similarity), Prauserella rugosa DSM 43194(T) (96.4%) and Prauserella flava YIM 90630(T) (95.9%). Based on the evidence of the present study, strain SCSIO 11529(T) is considered to represent a novel species of the genus Prauserella, for which the name Prauserella coralliicola sp. nov. is proposed. The type strain is SCSIO 11529(T) ( = DSM 45821(T) = NBRC 109418(T)).

Arthrobacter pityocampae sp. nov., isolated from Thaumetopoea pityocampa (Lep., Thaumetopoeidae).
A bacterium (strain Tp2(T)) was isolated from a caterpillar of the pine processionary moth, Thaumetopoea pityocampa (Den. & Schiff.) (Lepidoptera: Thaumetopoeidae), a destructive pine forest pest. The bacterium is a Gram-stain-positive, red-pigmented coccus, oxidase-negative, nitrate-reducing, non-motile and non-spore-forming. Strain Tp2(T) was subjected to a taxonomic study using polyphasic approach that included morphological and biochemical characterizations, 16S rRNA gene sequence analysis, DNA-DNA hybridization, DNA G+C content analysis, comparative fatty acid profiles, and analyses of quinones and polar lipids. The 16S rRNA gene sequence of strain Tp2(T) revealed that Arthrobacter agilis DSM 20550(T) was the closest known strain (98% 16S rRNA gene sequence similarity). DNA-DNA hybridization of A. agilis DSM 20550(T) and strain Tp2(T) resulted in a DNA-DNA relatedness value of 11.9% (20.2% reciprocal). The DNA base composition of strain Tp2(T) was 69.5 mol%, which is consistent with the other recognized members of Actinobacteria that have a high G+C content in their genome. The polar lipid pattern of strain Tp2(T) consisted of diphosphatidylglycerol (major), phosphatidylglycerol and phosphatidylinositol and unknown glycolipids. The cellular fatty acids were anteiso C15:0 and anteiso C17:0 and the major menaquinone was MK-9(II-H2). The peptidoglycan type was A3α with an L-Lys-L-Thr-L-Ala3 interpeptide bridge. The above-mentioned characterization qualifies strain Tp2(T) as genotypically and phenotypically distinct from closely related species of the genus Arthrobacter with validly published names. Strain Tp2(T) is therefore proposed to represent a novel species of the genus Arthrobacter, described as Arthrobacter pityocampae sp. nov. The type strain is Tp2(T) ( = DSM 21719(T) = NCCB 100254(T)).

Tessaracoccus lapidicaptus sp. nov., an actinobacterium isolated from the deep subsurface of the Iberian pyrite belt.
A novel actinobacterium, designated IPBSL-7(T), was isolated from a drilling core 297 m deep obtained from the Iberian Pyrite Belt. The strain was isolated anaerobically using nitrate as the electron acceptor. 16S rRNA gene sequence analysis revealed that it was related to Tessaracoccus flavescens SST-39(T) (95.7% similarity), Tessaracoccus bendigoensis Ben 106(T) (95.7%), Tessaracoccus lubricantis KSS-17Se(T) (95.6%) and Tessaracoccus oleiagri SL014B-20A1(T) (95.0%), while its similarity to any other member of the family Propionibacteriaceae was less than 94%. Cells were non-motile, non-spore-forming, Gram-positive, oval to rod-shaped, and often appeared in pairs or small groups. The strain was facultatively anaerobic, oxidase-negative, catalase-positive and capable of reducing nitrate. Colonies were circular, convex, smooth and colourless. The organism could grow at between 15 and 40 °C, with an optimal growth at 37 °C. The pH range for growth was from pH 6 to 9, with pH 8 being the optimal value. Strain IPBSL-7(T) had peptidoglycan type A3-γ', with ll-diaminopimelic acid as the diagnostic diamino-acid and glycine at position 1 of the peptide subunit. The dominant menaquinone was MK-9(H4) (93.8%). The major cellular fatty acid was anteiso-C15:0 (55.0%). The DNA G+C content was 70.3 mol%. On the basis of phenotypic and phylogenetic results, strain IPBSL-7(T) can be differentiated from previously described species of the genus Tessaracoccus and, therefore, represents a novel species, for which the name Tessaracoccus lapidicaptus sp. nov. is proposed. The type strain is IPBSL-7(T) ( = CECT 8385(T) = DSM 27266(T)).

Allokutzneria oryzae sp. nov., isolated from rhizospheric soil of Oryza sativa L.
The taxonomic status of a rhizospheric soil actinomycete, designated R8-39(T), was established using a polyphasic approach. The organism had phenotypic and morphological characteristics consistent with its classification in the genus Allokutzneria. Phylogenetic analysis based on an almost complete 16S rRNA gene sequence showed that the strain formed a monophyletic clade with the type strains of members of the genus Allokutzneria. Strain R8-39(T) displayed the highest levels of 16S rRNA gene sequence similarity to Allokutzneria albata DSM 44149(T) (98.8%) and Allokutzneria multivorans YIM 120521(T) (98.3%). However, the DNA-DNA hybridization values between strain R8-39(T) and A. albata and A. multivorans were clearly below the 70% threshold. The organism was found to have chemical characteristics consistent with its classification in the genus Allokutzneria. Whole-cell hydrolysates contained meso-diaminopimelic acid, arabinose, galactose, glucose, mannose, rhamnose and ribose. The main menaquinone was MK-9(H4). No mycolic acid was detected. The G+C content of the genomic DNA was 71.8 mol%. In addition, strain R8-39(T) had a phenotypic profile that readily distinguished it from recognized representatives of the genus Allokutzneria. It is evident from the combined genotypic and phenotypic properties that strain R8-39(T) represents a novel species of the genus Allokutzneria. The proposed name for this species is Allokutzneria oryzae sp. nov.; the type strain is R8-39(T) ( = BCC 60399(T) = NBRC 109649(T)).

Gordonia iterans sp. nov., isolated from a patient with pneumonia.
A second novel clinical actinobacterial strain, designated IFM 10348(T), was isolated from the sputum of the same Japanese patient with bacterial pneumonia from whom the type strain of Gordonia araii had been isolated. The strains differed in phylogenetic position and drug-resistance profiles. The taxonomic position of strain IFM 10348(T) was clarified by phenotypic, chemotaxonomic and phylogenetic studies. Phylogenetic analyses based on 16S rRNA gene sequences clearly demonstrated that strain IFM 10348(T) occupied a distinct clade within the genus Gordonia and was related closely to Gordonia malaquae DSM 45064(T) and Gordonia hirsuta DSM 44140(T) (97.3 and 97.1% similarities, respectively). Strain IFM 10348(T) was also clearly differentiated from G. malaquae DSM 45064(T) and G. hirsuta DSM 44140(T) based on gyrB and secA1 gene sequence similarity values. Strain IFM 10348(T) had MK-9(H2) as the predominant menaquonine, contained meso-diaminopimelic acid, arabinose, galactose and glucosamine as cell-wall components, and contained C18:1ω9c, summed feature 3 (C16:1ω7c and/or C16:1ω6c) and C16:0 as the major cellular fatty acids. Mycolic acids were present. The DNA G+C content of strain IFM 10348(T) was 68.0 mol%. DNA-DNA relatedness data coupled with the combination of genotypic and phenotypic data indicated that strain IFM 10348(T) represents a novel species of the genus Gordonia, for which the name Gordonia iterans sp. nov. is proposed.

The isolate was characterized using a polyphasic approach. 16S rRNA gene sequence analysis indicated that strain TRM 45123(T) belonged to the genus Saccharopolyspora and was closely related to Saccharopolyspora gloriosae (96.7% similarity). The G+C content of the DNA was 69.07 mol%. The isolate contained meso-diaminopimelic acid as the diagnostic diamino acid, and arabinose and ribose as the major whole-cell sugars. The diagnostic phospholipids were phosphatidylethanolamine, phosphatidylcholine and phosphatidylglycerol. The predominant menaquinone was MK-9(H4). The major fatty acids were iso-C16 : 0, anteiso-C17:0, iso-C15:0 and anteiso-C15:0.

Prauserella shujinwangii sp. nov., from a desert environment.
A Gram-positive, spore-forming, rod-shaped actinomycete, designated XJ46(T), was isolated from Xinjiang Uyghur Autonomous Region, China and subjected to a polyphasic taxonomic analysis. Morphological and chemotaxonomic characteristics of XJ46(T) were identified as being similar to those of members of the genus Prauserella. The phylogenetic tree based on 16S rRNA gene sequences showed that XJ46(T) shared the highest similarity (95.9%) with Prauserella marina MS498(T). Based on its phenotypic characteristics, chemotaxonomic analysis and 16S rRNA gene sequence analysis, strain XJ46(T) is proposed to represent a novel species of the genus Prauserella, named Prauserella shujinwangii sp. nov.

Kribbella shirazensis sp. nov., isolated from Iranian soil.
The taxonomic position of a strain isolated from soil in Shiraz, Fars province, Iran, was investigated. Strain UTMC 693(T) produced an extensively branched substrate mycelium and aerial hyphae consisting of hyphae that fragment into short to elongated rod-like elements. The chemotaxonomic characteristics of the isolate matched those described for the genus Kribbella. Strain UTMC 693(T) showed the highest 16S rRNA gene sequence similarity to Kribbella karoonensis DSM 17344(T) (98.3%), K. swartbergensis DSM 17345(T) (98.2%), K. hippodromi S1.4(T) (98.0%), K. aluminosa HKI 0478(T) (98.0%) and K. jejuensis HD9(T) (98.0%). DNA-DNA hybridization studies with closely related type strains showed 56.3% relatedness to K. karoonensis, 21.3% to K. swartbergensis, 39.0% to K. jejuensis and 42.0% to K. aluminosa. Thus, strain UTMC 693(T) can be considered to represent a novel Kribbella species. Strain UTMC 693(T) showed the typical morphology found among members of Kribbella, but can be differentiated easily from closely related species by genotypic characteristics, chemotaxonomic results and other phenotypic markers. Based on these results, strain UTMC 693(T) ( =DSM 45490(T) =CCUG 61792(T)) is considered the type strain of a novel species of the genus Kribbella, for which the name Kribbella shirazensis sp. nov. is proposed.

Ilumatobacter nonamiense sp. nov. and Ilumatobacter coccineum sp. nov., isolated from seashore sand.
Bacterial strains YM16-303(T) and YM16-304(T) were isolated from a sample of seashore sand using a medium with an artificial seawater base. Both isolates grew slowly on marine agar, and were found to be Gram-reaction-positive, aerobic, non-motile and rod-shaped. The cell-wall peptidoglycan contained ll-diaminopimelic acid, glycine, alanine and hydroxyglutamic acid, and the acyl type of the muramic acid was glycolyl. The predominant menaquinone was MK-9(H8). The 16S rRNA gene sequences of strains YM16-303(T) and YM16-304(T) were most similar to that of Ilumatobacter fluminis YM22-133(T), and phylogenetic analyses also indicated that they belong to the genus Ilumatobacter. Ilumatobacter fluminis YM22-133(T) and strains YM16-303(T) and YM16-304(T) should be classified as distinct species in the genus Ilumatobacter, however, since the 16S rRNA gene sequence similarity between them was low and the major cellular fatty acids and some physiological properties were different. Moreover, average nucleotide identity and maximal unique exact matches index values also supported the conclusion that they represent different species. On the basis of the above analyses, two novel species, Ilumatobacter nonamiense sp. nov. (type strain YM16-303(T) = NBRC 109120(T) = KCTC 29139(T)) and Ilumatobacter coccineum sp. nov. (type strain YM16-304(T) = NBRC 103263(T) = KCTC 29153(T)), are proposed. The order Acidimicrobiales, which contains the genus Ilumatobacter, currently includes six genera and only six species, and they are phylogenetically very far from each other. Phylogenetic analyses revealed that strains YM16-303(T) and YM16-304(T) clustered with closely related uncultured actinobacteria but not Ilumatobacter fluminis YM22-133(T), suggesting that many uncultured bacteria related to these isolates exist in the environment. This is the first report on interspecies relationships in the order Acidimicrobiales.

Geodermatophilus normandii sp. nov., isolated from Saharan desert sand.
A novel Gram-reaction-positive actinobacterial strain, designated CF5/3(T), was isolated from a sand sample obtained in the Sahara Desert, Chad. The greenish-black-pigmented isolate was aerobic and exhibited optimal growth from 25-40 °C at pH 6.0-10.0 with 0-1% (w/v) NaCl. Chemotaxonomic and molecular characteristics of the isolate matched those described for members of the genus Geodermatophilus. The DNA G+C content of the genome of the novel strain was 75.5 mol%. The peptidoglycan contained meso-diaminopimelic acid as diagnostic diamino acid. The main phospholipids were diphosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol and a minor fraction of phosphatidylglycerol. MK-9(H4) was the dominant menaquinone, and galactose was detected as a diagnostic sugar. The major cellular fatty acids were branched-chain saturated acids: iso-C(15:0) and iso-C(16:0). Analysis of 16S rRNA gene sequences showed 95.6-98.8% pairwise sequence identity with the members of the genus Geodermatophilus. Based on phenotypic and chemotaxonomic properties, as well as phylogenetic distinctiveness, the isolate represents a novel species, Geodermatophilus normandii, with the type strain CF5/3(T) ( =DSM 45417(T) =CCUG 62814(T) =MTCC 11412(T)).

Streptomyces harbinensis sp. nov., an endophytic, ikarugamycin-producing actinomycete isolated from soybean root [Glycine max (L.) Merr].
A novel ikarugamycin-producing actinomycete, designated strain NEAU-Da3(T), was isolated from soybean root [Glycine max (L.) Merr.] and characterized using a polyphasic approach. 16S rRNA gene sequence similarity studies showed that strain NEAU-Da3(T) belonged to the genus Streptomyces, and was most closely related to Streptomyces carpaticus NRRL B-16359(T) (99.5 %), Streptomyces cheonanensis VC-A46(T) (99.3 %) and Streptomyces xiamenensis MCCC 1A01550(T) (97.2 %); similarities to other type strains of species of the genus Streptomyces were lower than 97.1 %. The maximum-likelihood phylogenetic tree based on 16S rRNA gene sequences showed that the isolate formed a distinct phyletic line with S. carpaticus NRRL B-16359(T), S. cheonanensis VC-A46(T) and S. xiamenensis MCCC 1A01550(T). This branching pattern was also supported by the tree reconstructed with the neighbour-joining method. A comparative study between strain NEAU-Da3(T) and the type strains of the closest related species of the genus Streptomyces revealed that it differed from them in morphological, physiological and biochemical characteristics. Therefore, it is proposed that strain NEAU-Da3(T) represents a novel species of the genus Streptomyces, for which the name Streptomyces harbinensis sp. nov. is proposed. The type strain is NEAU-Da3(T) ( = CGMCC 4.7047(T) = DSM 42076(T)).

Kribbella albertanoniae sp. nov., isolated from a Roman catacomb, and emended description of the genus Kribbella.
A novel actinobacterium, strain BC640(T), was isolated from a biofilm sample collected in 2009 in the Saint Callistus Roman catacombs. Analysis of the 16S rRNA gene sequence showed that the strain belonged to the genus Kribbella. Phylogenetic analysis using the 16S rRNA gene and concatenated gyrB, rpoB, relA, recA and atpD gene sequences showed that strain BC640(T) was most closely related to the type strains of Kribbella yunnanensis and Kribbella sandramycini. Based on gyrB genetic distance analysis, strain BC640(T) was shown to be distinct from all Kribbella type strains. DNA-DNA hybridization experiments confirmed that strain BC640(T) represents a genomic species distinct from its closest phylogenetic relatives, K. yunnanensis DSM 15499(T) (53.5±7.8 % DNA relatedness) and K. sandramycini DSM 15626(T) (33.5±5.0 %). Physiological comparisons further showed that strain BC640(T) is phenotypically distinct from the type strains of K. yunnanensis and K. sandramycini. Strain BC640(T) ( = DSM 26744(T) = NRRL B-24917(T)) is thus presented as the type strain of a novel species, for which the name Kribbella albertanoniae sp. nov. is proposed.

Lechevalieria nigeriaca sp. nov., isolated from arid soil.
A novel actinobacterium, designated strain NJ2035(T), was isolated from soil collected from Abuja, Nigeria and was characterized to determine its taxonomic position. The isolate was found to have chemical and morphological properties associated with members of the genus Lechevalieria. Phylogenetic analyses based on almost-complete 16S rRNA gene sequences indicated that the isolate was closely related to members of the genus Lechevalieria, and was shown to form a distinct phyletic line in the Lechevalieria phylogenetic tree. Strain NJ2035(T) was most closely related to Lechevalieria roselyniae C81(T), Lechevalieria atacamensis C61(T) and Lechevalieria deserti C68(T) (98.5 % 16S rRNA gene sequence similarity). Sequence similarities with other members of the genus Lechevalieria were less than 98.2 %. The cell wall of the novel strain contained meso-diaminopimelic acid, and galactose, mannose and rhamnose as the diagnostic sugars. The predominant menaquinone was MK-9(H4). The polar lipids detected were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and phosphatidylinositol. DNA-DNA relatedness and phenotypic data showed that the novel isolate and L. roselyniae C81(T), L. atacamensis C61(T) and L. deserti C68(T) belong to distinct genomic species. On the basis of data from this taxonomic study using a polyphasic approach, strain NJ2035(T) represents a novel species of the genus Lechevalieria, for which the name Lechevalieria nigeriaca sp. nov. is proposed. The type strain is NJ2035(T) ( = DSM 45680(T) = KCTC 29057(T) = NRRL B-24881(T)).

Saccharothrix saharensis sp. nov., an actinomycete isolated from Algerian Saharan soil.
The taxonomic position of a novel actinomycete, strain SA152(T), isolated from a sample of Algerian Saharan soil, was determined using a polyphasic taxonomic approach. The strain produced abundant aerial mycelium and fragmented substrate mycelium on most media tested. Chemotaxonomically and phylogenetically, the strain was related to the members of the genus Saccharothrix. Results of 16S rRNA gene sequence comparison revealed that strain SA152(T) shared the highest degree of 16S rRNA gene sequence similarity with Saccharothrix xinjiangensis NBRC 101911(T) (99.3 %) and Saccharothrix texasensis NRRL B-16134(T) (98.9 %). However, DNA-DNA hybridization studies showed only 16.2 % relatedness with S. xinjiangensis DSM 44896(T) and 33.9 % relatedness with S. texasensis DSM 44231(T). Based upon genotypic and phenotypic differences from other members of the genus, a novel species, Saccharothrix saharensis sp. nov., is proposed, with SA152(T) ( = DSM 45456(T) = CCUG 60213(T)) as the type strain.

Streptomyces kebangsaanensis sp. nov., an endophytic actinomycete isolated from an ethnomedicinal plant, which produces phenazine-1-carboxylic acid.
A spore-forming streptomycete designated strain SUK12(T) was isolated from a Malaysian ethnomedicinal plant. Its taxonomic position, established using a polyphasic approach, indicates that it is a novel species of the genus Streptomyces. Morphological and chemical characteristics of the strain were consistent with those of members of the genus Streptomyces. Analysis of the almost complete 16S rRNA gene sequence placed strain SUK12(T) in the genus Streptomyces where it formed a distinct phyletic line with recognized species of this genus. The strain exhibited highest sequence similarity to Streptomyces corchorusii DSM 40340(T) (98.2 %) followed by Streptomyces chrestomyceticus NRRL B-3310(T) (98.1 %). The G+C content of the genomic DNA was 74 mol%. Chemotaxonomic data [MK-9(H8) as the major menaquinone; LL-diaminopimelic acid as a component of cell-wall peptidoglycan; C12 : 0, C14 : 0, C15 : 0 and C17 : 1 as the major fatty acids; phospholipid type II] supported the affiliation of strain SUK12(T) to the genus Streptomyces. The results of the phylogenetic analysis and phenotypic data derived from this and previous studies allowed the genotypic and phenotypic differentiation of strain SUK12(T) from the related species of the genus Streptomyces. The DNA-DNA relatedness value between strain SUK12(T) and S. corchorusii DSM 40340(T) is 18.85±4.55 %. Strain SUK12(T) produces phenazine-1-carboxylic acid, known as tubermycin B, an antibacterial agent. It is proposed, therefore, that strain SUK12(T) ( = DSM 42048(T) = NRRL B-24860(T)) be classified in the genus Streptomyces as the type strain of Streptomyces kebangsaanensis sp. nov.

An actinomycete with well-branched mycelia, designated strain YIM 120521(T), was isolated from soil collected from the banks of the Nujiang River, Yunnan Province, south-west China. Both aerial and substrate mycelia were white and non-pigmented. Growth was observed at 4-40 °C (optimum 28 °C), pH 6.0-9.0 (optimum 7.0) and in 0-4 % (w/v) NaCl (optimum 0 %). Analysis of the 16S rRNA gene sequence revealed that strain YIM 120521(T) belongs to the genus Allokutzneria with the highest sequence similarity to Allokutzneria albata DSM 44149(T) (98.4 %). However, the mean DNA-DNA relatedness value between the two strains was below 70 %. Chemotaxonomic characteristics supported the inclusion of strain YIM 120521(T) in the genus Allokutzneria, with rhamnose, arabinose, glucose, galactose and mannose as the whole-cell sugars, meso-diaminopimelic acid as the cell-wall diamino acid and MK-9(H4) as the predominant menaquinone. On the basis of physiological, biochemical and chemotaxonomic characteristics, strain YIM 120521(T) is considered to represent a novel species of the genus Allokutzneria, for which the name Allokutzneria multivorans sp. nov. is proposed. The type strain is YIM 120521(T) ( = JCM 17342(T) = DSM 45532(T)).

Pseudomonas guariconensis sp. nov., isolated from rhizospheric soil.
We isolated a bacterial strain designated PCAVU11(T) in the course of a study of phosphate-solubilizing bacteria occurring in rhizospheric soil of Vigna unguiculata (L.) Walp. in Guárico state, Venezuela. The 16S rRNA gene sequence had 99.2 % sequence similarity with respect to the most closely related species, Pseudomonas taiwanensis, and 99.1 % with respect to Pseudomonas entomophila, Pseudomonas plecoglossicida and Pseudomonas monteilii, on the basis of which PCAVU11(T) was classified as representing a member of the genus Pseudomonas. Analysis of the housekeeping genes rpoB, rpoD and gyrB confirmed the phylogenetic affiliation and showed sequence similarities lower than 95 % in all cases with respect to the above-mentioned closest relatives. Strain PCAVU11(T) showed two polar flagella. The respiratory quinone was Q9. The major fatty acids were 16 : 0 (25.7 %), 18 : 1ω7c (20.4 %), 17 : 0 cyclo (11.5 %) and 16 : 1ω7c/15 : 0 iso 2-OH in summed feature 3 (10.8 %). The strain was oxidase-, catalase- and urease-positive, the arginine dihydrolase system was present but nitrate reduction, β-galactosidase production and aesculin hydrolysis were negative. Strain PCAVU11(T) grew at 44 °C and at pH 10. The DNA G+C content was 61.5 mol%. DNA-DNA hybridization results showed values lower than 56 % relatedness with respect to the type strains of the four most closely related species. Therefore, the results of genotypic, phenotypic and chemotaxonomic analyses support the classification of strain PCAVU11(T) as representing a novel species of the genus Pseudomonas, which we propose to name Pseudomonas guariconensis sp. nov. The type strain is PCAVU11(T) ( = LMG 27394(T) = CECT 8262(T)).

Corynebacterium frankenforstense sp. nov. and Corynebacterium lactis sp. nov., isolated from raw cow milk.
Two groups of Gram-stain positive, aerobic bacterial strains were isolated from raw cow's milk, from a milking machine and from bulk tank milk. Based on their 16S rRNA gene sequences these isolates formed two distinct groups within the genus Corynebacterium. The sequence similarities of the isolates to the type strains of species of the genus Corynebacterium were below 98.4%. The presence of menaquinones MK-8(H2) and MK-9(H2), the predominant fatty acid 18:1 cis 9 and a polar lipid pattern with several phospholipids but without aminolipids was in accord with the characteristics of this genus. The results of DNA-DNA hybridization, biochemical tests and chemotaxonomic properties allowed genotypic and phenotypic differentiation of the strains from all known species of the genus Corynebacterium. Therefore, the isolates were assigned to two novel species of this genus for which the names Corynebacterium frankenforstense sp. nov. (type strain ST18(T) =DSM 45800(T) = CCUG 63371(T)), and Corynebacterium lactis sp. nov. (type strain RW2-5(T) = DSM 45799(T) = CCUG 63372(T)) are proposed, respectively.

Kallotenue papyrolyticum gen. nov., sp. nov., a cellulolytic and filamentous thermophile that represents a novel lineage (Kallotenuales ord. nov., Kallotenuaceae fam. nov.) within the class Chloroflexia.
Several closely related, thermophilic and cellulolytic bacterial strains, designated JKG1(T), JKG2, JKG3, JKG4 and JKG5, were isolated from a cellulolytic enrichment (corn stover) incubated in the water column of Great Boiling Spring, NV. Strain JKG1(T) had cells of diameter 0.7-0.9 µm and length ~2.0 µm that formed non-branched, multicellular filaments reaching >300 µm. Spores were not formed and dense liquid cultures were red. The temperature range for growth was 45-65 °C, with an optimum of 55 °C. The pH range for growth was pH 5.6-9.0, with an optimum of pH 7.5. JKG1(T) grew as an aerobic heterotroph, utilizing glucose, sucrose, xylose, arabinose, cellobiose, CM-cellulose, filter paper, microcrystalline cellulose, xylan, starch, Casamino acids, tryptone, peptone, yeast extract, acetate, citrate, lactate, pyruvate and glycerol as sole carbon sources, and was not observed to photosynthesize. The cells stained Gram-negative. Phylogenetic analysis using 16S rRNA gene sequences placed the new isolates in the class Chloroflexia, but distant from other cultivated members, with the highest sequence identity of 82.5 % to Roseiflexus castenholzii. The major quinone was menaquinone-9; no ubiquinones were detected. The major cellular fatty acids (>5 %) were C18 : 0, anteiso-C17 : 0, iso-C18 : 0, iso-C17 : 0, C16 : 0, iso-C16 : 0 and C17 : 0. The peptidoglycan amino acids were alanine, ornithine, glutamic acid, serine and asparagine. Whole-cell sugars included mannose, rhamnose, glucose, galactose, ribose, arabinose and xylose. Morphological, phylogenetic and chemotaxonomic results suggest that JKG1(T) is representative of a new lineage within the class Chloroflexia, which we propose to designate Kallotenue papyrolyticum gen. nov., sp. nov., Kallotenuaceae fam. nov., Kallotenuales ord. nov. The type strain of Kallotenue papyrolyticum gen. nov., sp. nov. is JKG1(T) ( = DSM 26889(T) = JCM 19132(T)).

Streptomyces yaanensis sp. nov., isolated from soil.
A novel actinomycete, designated Z4(T), was isolated from soil in Yaan, Sichuan Province, south China. The taxonomic status of this strain was established using a polyphasic approach. The morphological and chemotaxonomic characteristics of the organism are typical of the members of the genus Streptomyces. Phylogenetic analysis based on the almost complete 16S rRNA gene sequence indicated that strain Z4(T) belonged to the genus Streptomyces, branching off next to Streptomyces durhamensis ATCC 23194(T) (98.7 %), Streptomyces puniciscabiei KACC 20253(T) (98.7 %) and Streptomyces filipinensis ATCC 23905(T) (98.6 %). However, DNA-DNA hybridization studies and phenotypic differences between strain Z4(T) and closely related species of the genus Streptomyces suggested that strain Z4(T) represented a different genomic species. It is therefore proposed that Z4(T) ( = CGMCC 4.7035(T) = KCTC 29111(T)) represents the type strain of a novel species of the genus Streptomyces, for which the name Streptomyces yaanensis sp. nov. is proposed.

Haloferula chungangensis sp. nov., isolated from marine sediment.
A Gram-stain-negative, non-spore-forming, non-motile, strictly aerobic, rod-shaped bacterial strain, designated CAU 1074(T), was isolated from marine sediment and its taxonomic position was investigated using a polyphasic approach. Strain CAU 1074(T) grew optimally at 30 °C and pH 6.5. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain CAU 1074(T) formed a distinct lineage within the genus Haloferula and was most closely related to Haloferula harenae KCTC 22198(T) (96.0% similarity). Strain CAU 1074(T) contained MK-9 as the major isoprenoid quinone, and iso-C(14:0,) C(16:1)ω9c and C(16:0) as the major fatty acids. The cell wall peptidoglycan contained meso-diaminopimelic acid. The major whole-cell sugars were glucose, xylose, mannose and ribose. The polar lipids were composed of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, aminoglycolipid and two unidentified phospholipids. The DNA G+C content of the strain was 64.0 mol%. On the basis of phenotypic and chemotaxonomic data, and phylogenetic inference, strain CAU 1074(T) should be classified as a member of a novel species in the genus Haloferula, for which the name Haloferula chungangensis sp. nov. is proposed; the type strain is CAU 1074(T) (= KCTC 23578(T) = CCUG 61920(T)).

Cellulomonas soli sp. nov. and Cellulomonas oligotrophica sp. nov., isolated from soil.
Two novel bacterial strains, designated Kc1(T) and Kc5(T), were isolated from soil in Japan. Cells of the novel strains were Gram-reaction-positive, aerobic or facultatively anaerobic, motile rods. Phylogenetic analyses based on 16S rRNA gene sequences indicated that both strains belonged to the genus Cellulomonas. The 16S rRNA gene sequences of strains Kc1(T) and Kc5(T) showed closest similarity to that of Cellulomonas terrae DB5(T) (98.1 % and 98.4 % similarity, respectively), and the 16S rRNA gene similarity between the two novel strains was 97.8 %. In both strains, the major menaquinone was MK-9(H(4)), the predominant polar lipids were diphosphatidylglycerol and phosphatidylinositol mannosides, and the peptidoglycan contained ornithine and glutamic acid. Cell-wall sugars were identified as rhamnose, galactose and mannose in strain Kc1(T) and rhamnose and glucose in strain Kc5(T). The DNA G+C contents of strains Kc1(T) and Kc5(T) were 73.6 mol% and 75.8 mol%, respectively. Based on the chemotaxonomic and physiological data and the results of DNA-DNA hybridizations, the two strains represent two novel species within the genus Cellulomonas, for which the names Cellulomonas soli sp. nov. (type strain Kc1(T) =DSM 24484(T) =JCM 17535(T)) and Cellulomonas oligotrophica sp. nov. (type strain Kc5(T) =DSM 24482(T) =JCM 17534(T)) are proposed.

Kutzneria buriramensis sp. nov., isolated from soil, and emended description of the genus Kutzneria.
A Gram-staining-positive, filamentous bacterium, which developed large globose sporangia at the ends of long sporangiophores on aerial mycelium, was isolated from dry soil collected in a deciduous forest in Thailand. The cell-wall peptidoglycan of the novel bacterium, which was designated strain A-T 1846(T), contained meso-diaminopimelic acid and the whole-cell sugars comprised rhamnose, ribose, mannose, glucose and galactose. The predominant menaquinone was MK-9(H(4)). Mycolic acids were not detected. The identified phospholipids were phosphatidylmethylethanolamine, phosphatidylethanolamine, hydroxyphosphatidylethanolamine, phosphatidylinositol, phosphatidylglycerol and diphosphatidylglycerol. The predominant cellular fatty acids were iso-C(16:0), iso-C(16 : 0) 2-OH and C(16 : 0) 10-methyl. The G+C content of the genomic DNA was 72 mol%. The phenotypic and chemotaxonomic characteristics of the novel strain resembled those of established members of the genus Kutzneria. Phylogenetic analyses based on 16S rRNA gene sequences also indicated that this strain belonged to the genus Kutzneria but as a representative of a putative novel species. In hybridization experiments, the DNA-DNA relatedness values recorded between the novel strain and established members of the genus Kutzneria all fell well below 70 %. Based on the phenotypic, chemotaxonomic and genotypic evidence and the results of the DNA-DNA hybridizations, strain A-T 1846(T) represents a novel species in the genus Kutzneria, for which the name Kutzneria buriramensis sp. nov. is proposed. The type strain is A-T 1846(T) (=BCC 29373(T) =NBRC 107931(T)). An emended description of the genus Kutzneria is provided.

Nonomuraea jabiensis sp. nov., isolated from arid soil.
A novel actinomycete, strain A4036(T), was isolated from a soil sample collected from the Jabi district in Abuja, Nigeria. The taxonomic position of strain A4036(T) was established using a combination of genotypic and phenotypic analyses. The organism formed extensively branched substrate and aerial hyphae that generated spiral chains of spores with warty surfaces. The cell wall contained meso-diaminopimelic acid and the cell-wall sugars were glucose, madurose, mannose and ribose. The predominant menaquinone was MK-9(H(4)). The polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, phosphatidylmethylethanolamine, phosphatidylinositol mannoside, hydroxy-phosphatidylethanolamine, hydroxy-phosphatidylmethylethanolamine, two unidentified phospholipids and four unknown glucosamine-containing phospholipids. The major cellular fatty acids were iso-C(16 : 0) 2-OH, iso-C(16 : 0) and 10-methyl C(17 : 0). On the basis of 16S rRNA gene sequence similarity studies, strain A4036(T) grouped in the genus Nonomuraea, being most closely related to Nonomuraea angiospora IFO 13155(T) (99.05 %), Nonomuraea candida HMC10(T) (98.78 %), Nonomuraea kuesteri GW 14-1925(T) (98.49 %), Nonomuraea endophytica YIM 65601(T) (98.42 %), Nonomuraea maheshkhaliensis 16-5-14(T) (98.40 %), Nonomuraea turkmeniaca DSM 43926(T) (98.38 %), Nonomuraea helvata IFO 14681(T) (98.29 %), Nonomuraea rubra DSM 43768(T) (98.10 %) and Nonomuraea salmonea DSM 43678(T) (98.06 %). Levels of 16S rRNA gene sequence similarity to the type strains of other species of the genus Nonomuraea were <98 %. Despite the high 16S rRNA gene sequence similarities, DNA-DNA relatedness values and phenotypic data demonstrated that strain A4036(T) was clearly distinguished from all closely related species of the genus Nonomuraea. Thus, this isolate is considered to represent a novel species of the genus Nonomuraea, for which the name Nonomuraea jabiensis sp. nov. is proposed. The type strain is A4036(T) (= DSM 45507(T) = KCTC 19870(T)).

Streptomyces endophyticus sp. nov., an endophytic actinomycete isolated from Artemisia annua L.
Three filamentous actinomycetes, strains YIM 65594(T), YIM 65638 and YIM 65642, were isolated from the surface-sterilized roots of Artemisia annua L. collected from Yunnan province, south-west China. These strains were found to have morphological and chemotaxonomic characteristics typical of the genus Streptomyces. The organisms formed an extensively branched substrate mycelium, with abundant aerial hyphae that differentiated into spores. The cell wall of the isolates contained ll-diaminopimelic acid and the menaquinones were MK-9(H(8)) and MK-9(H(6)). The major fatty acids were anteiso-C(15 : 0), anteiso-C(17 : 0) and iso-C(16 : 0). Phylogenetic analysis of the 16S rRNA gene sequences of these strains revealed that the strains clustered together and were most closely related to Streptomyces kunmingensis NBRC 14463(T), with 98.5-98.6 % 16S rRNA gene sequence similarity. The results of DNA-DNA hybridization and physiological tests allowed the genotypic and phenotypic differentiation of strains YIM 65594(T), YIM 65638 and YIM 65642 from related species. However, the high level of DNA-DNA relatedness between them showed that these three strains belong to the same species. Strain YIM 65594(T) (= DSM 41984(T) = CCTCC AA 209036(T)) was selected as the type strain to represent this novel species, for which the name Streptomyces endophyticus sp. nov. is proposed.

Gordonia phosphorivorans sp. nov., isolated from a wastewater bioreactor with phosphorus removal.
Two Gram-stain-positive, non-endospore-forming actinobacteria (Ca8(T)and Ca14) were isolated from a bioreactor with extensive phosphorus removal. Based on 16S rRNA gene sequence similarity comparisons, strains Ca8(T) and Ca14 were shown to belong to the genus Gordonia and were most closely related to Gordonia hirsuta DSM 44140(T) (98.0 % sequence similarity) and Gordonia hydrophobica DSM 44015(T) (97.2 %). In comparison with the sequences of the type strains of all other species of the genus Gordonia tested, similarities were below 97 %. The quinone systems of the strains were determined to consist predominantly of MK-9H(2). The polar lipid profile for both organisms consisted of diphosphatidylglycerol, phosphatidylglycerol, phospatidylethanolamine, phosphatidylinositol and phosphatidylinositol mannoside. Whole-organism hydrolysates contained meso-diaminopimelic acid as the diamino acid of the peptidoglycan; mycolic acids were detected as well. These chemotaxonomic traits and the major fatty acids, which were C(16 : 1)cis-9, C(16 : 0) and C(18 : 1) and tuberculostearic acid strongly supported the grouping of strains Ca8(T) and Ca14 into the genus Gordonia. The two strains showed a DNA-DNA similarity of 96 %. DNA-DNA hybridizations of strain Ca8(T) with G. hirsuta DSM 44140(T) and G. hydrophobica DSM 44015(T) resulted in values of 26.3 and 25.0 %, respectively. These results and those of the physiological and biochemical tests allowed a clear phenotypic differentiation of strains Ca8(T) and Ca14 from the most closely related species of the genus Gordonia. It is concluded that strains Ca8(T) and Ca14 represent a novel species, for which the name Gordonia phosphorivorans sp. nov. is proposed, with the type strain Ca8(T) (= DSM 45630(T) = CCUG 61533(T) = CCM 7957(T) = LMG 26648(T)).

Gordonia alkaliphila sp. nov., an actinomycete isolated from tidal flat sediment.
A Gram-stain-positive, non-motile, aerobic actinobacterium, designated strain CJ10(T), was isolated from tidal flat sediment from the Yellow Sea in South Korea. Strain CJ10(T) grew on tryptic soy agar in the presence of 0-4 % (w/v) NaCl (optimum growth in the absence of NaCl) and at pH 6-11 (optimum pH 9). On the basis of 16S rRNA gene sequence analysis, strain CJ10(T) belonged to the genus Gordonia and showed the highest sequence similarity to Gordonia hirsuta DSM 44140(T) (97.9 %) and Gordonia hydrophobica DSM 44015(T) (97.6 %). DNA-DNA relatedness levels of strain CJ10(T) were 47.4 % (CJ10(T) as probe) and 42.2 % (G. hirsuta DSM 44140(T) as probe) to G. hirsuta DSM 44140(T) and 8.6 % (CJ10(T) as probe) and 9.3 % (G. hydrophobica DSM 44015(T) as probe) to G. hydrophobica DSM 44015(T). The major isoprenoid quinone was MK-9(H(2)). The polar lipid profile of strain CJ10(T) consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol and phosphatidylinositol mannoside. The predominant cellular fatty acids were C(18 : 1)ω9c (38.0 %), C(16 : 0) (30.1 %) and summed feature 3 (C(16 : 1)ω6c and/or C(16 : 1)ω7c; 17.4 %). The DNA G+C content was 67.7 mol%. Therefore, the results from our polyphasic taxonomic study suggest that strain CJ10(T) represents a novel species in the genus Gordonia, for which the name Gordonia alkaliphila sp. nov. is proposed; the type strain is CJ10(T) (= KACC 16561(T) = JCM 18077(T)).

Actinomadura xylanilytica sp. nov., an actinomycete isolated from soil.
The taxonomic position of a soil isolate, strain BK147(T), was established using data from a polyphasic study. The organism showed a combination of chemotaxonomic and morphological characteristics consistent with its classification in the genus Actinomadura. It formed a distinct phyletic line in the phylogenetic tree based on 16S rRNA gene sequences of members of the genus Actinomadura and was most closely, albeit loosely, related to Actinomadura bangladeshensis DSM 45347(T), Actinomadura meyerae DSM 44715(T) and Actinomadura napierensis NRRL B-24319(T) but was readily distinguished from these strains using a range of phenotypic properties. Based on the combined genotypic and phenotypic data it is proposed that isolate BK147(T) ( = KACC 20919(T) = NCIMB 14771(T) = NRRL B-24852(T)) be classified as the type strain of a novel species of the genus Actinomadura, for which the name Actinomadura xylanilytica sp. nov. is proposed.

Angustibacter aerolatus sp. nov., isolated from air.
A novel actinomycete strain, 7402J-48(T), was isolated from an air sample collected from Jeju island, Republic of Korea. Cells were gram-positive, aerobic, flagellated, short rods. Strain 7402J-48(T) showed highest 16S rRNA gene sequence similarity (98.6 %) with Angustibacter luteus TT07R-79(T), and had relatively low sequence similarities (below 95.1 %) with other members of the family Kineosporiaceae. The cell wall of strain 7402J-48(T) contained alanine, glutamic acid and 2,6-diaminopimelic acid, suggesting A1γ-type peptidoglycan. The menaquinones were MK-9(H(4)) and MK-8(H(4)). The acyl type of the cell-wall muramic acid was acetyl. Diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannoside and an unknown lipid were present. The cellular fatty acid profile comprised a large amount of anteiso-C(15 : 0), moderate amounts of C(16 : 0), summed feature 3 (including C(16 : 1)ω7c and/or C(16 : 1)ω6c), C(17 : 0), iso-C(15 : 0), C(16 : 0) N alcohol and C(17 : 1)ω8c, and small amounts of other fatty acids. The DNA G+C content of strain 7402J-48(T) was 73 mol%. Based on its phenotypic and genotypic characteristics, strain 7402J-48(T) ( = KACC 15527(T) = NBRC 108730(T)) is proposed as the type strain of a novel species, Angustibacter aerolatus sp. nov.

Angustibacter peucedani sp. nov., isolated from rhizosphere soil.
A strictly aerobic, Gram-stain-positive actinobacterial strain was isolated from a rhizosphere soil of a wild plant (Peucedanum japonicum Thumb.) collected on Mara Island, Jeju, Republic of Korea. Cells of strain RS-50(T) were oxidase-negative, catalase-positive, short rods and motile by means of a polar flagellum; the colonies were orange, circular, smooth and convex. meso-Diaminopimelic acid and glucose were the diagnostic diamino acid in the cell wall and the whole-cell sugar, respectively. The major menaquinone was MK-9(H(4)). The polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannoside, two unknown phospholipids and an unknown lipid. The major fatty acids were iso-C(15 : 0), iso-C(16 : 0,) anteiso-C(15 : 0) and anteiso-C(17 : 0). The DNA G+C content was 73.6 mol%. In 16S rRNA gene sequence-based phylogenetic trees, strain RS-50(T) formed a tight cluster with Angustibacter luteus (99.2 % sequence similarity); both were loosely related to the suborders Kineosporiineae and Micrococcineae. The DNA-DNA relatedness value of the isolate to A. luteus KACC 14249(T) was 22.3±0.9 %. On the basis of the results of phenotypic analyses and DNA-DNA hybridization experiments, strain RS-50(T) is considered to represent a novel species of the genus Angustibacter, for which the name Angustibacter peucedani sp. nov. is proposed. The type strain is RS-50(T) ( = KCTC 19628(T) = DSM 45329(T)). The description of the genus Angustibacter is emended.

Amycolatopsis magusensis sp. nov., isolated from soil.
A novel actinomycete, designated strain KT2025(T), was isolated from arid soil collected from Magusa, northern Cyprus. The taxonomic position of the novel strain was established by using a polyphasic approach. The organism had chemical and morphological features consistent with its classification in the genus Amycolatopsis. Phylogenetic analyses based on 16S rRNA gene sequences supported the classification of the isolate in the genus Amycolatopsis and showed that the organism formed a cluster with Amycolatopsis nigrescens CSC17-Ta-90(T), Amycolatopsis minnesotensis 32U-2(T), Amycolatopsis sacchari DSM 44468(T) and Amycolatopsis dongchuanensis YIM 75904(T). 16S rRNA gene sequence similarity analysis indicated that strain KT2025(T) was most closely related to Amycolatopsis lurida DSM 43134(T) (97.5 %), Amycolatopsis keratiniphila subsp. keratiniphila DSM 44409(T) (97.4 %), Amycolatopsis keratiniphila subsp. nogabecina DSM 44586(T) (97.1 %), Amycolatopsis nigrescens DSM 44992(T) (97.1 %), Amycolatopsis azurea DSM 43854(T) (97.1 %) and Amycolatopsis minnesotensis DSM 44988(T) (96.9 %). The organism was found to have chemical features typical of members of the genus Amycolatopsis such as meso-diaminopimelic acid as the diagnostic diamino acid in the cell-wall peptidoglycan, and arabinose and galactose as diagnostic sugars. The predominant menaquinone was MK-9(H4). The polar lipids detected were phosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositol and hydroxy-phosphatidylethanolamine. The major fatty acids were iso-C16 : 0, iso-C15 : 0 and iso-C14 : 0. The G+C content of the genomic DNA was 70.8 mol%. Phenotypic data clearly distinguished the isolate from its closest relatives. The combined genotypic and phenotypic data and low levels of DNA-DNA relatedness with its closest relatives indicated that strain KT2025(T) represents a novel species of the genus Amycolatopsis, for which the name Amycolatopsis magusensis sp. nov. is proposed. The type strain is KT2025(T) ( = DSM 45510(T) = KCTC 29056(T)).

Kribbella endophytica sp. nov., an endophytic actinobacterium isolated from the surface-sterilized leaf of a native apricot tree.
A new strain of the genus Kribbella, PIP 118(T), was isolated from the leaf of an Australian native apricot tree (Pittosporum angustifolium), or Gumbi Gumbi in the indigenous language. This strain is an aerobic actinobacterium consisting of hyphae that fragment into short to elongated rod-like elements. Phylogenetic evaluation based on 16S rRNA gene sequence analysis placed this isolate as a member of the family Nocardioidaceae and most closely related to Kribbella antibiotica YIM 31530(T) (98.6 %) and Kribbella koreensis LM 161(T) (98.4 %). Chemotaxonomic data including cell wall components, major menaquinone and major fatty acids confirmed the affiliation of strain PIP 118(T) to the genus Kribbella. The results of the phylogenetic analysis, including physiological and biochemical studies in combination with DNA-DNA hybridization, allowed the genotypic and phenotypic differentiation of strain PIP 118(T) and members of the most closely related species with validly published names. The name proposed for the new species is Kribbella endophytica sp. nov. The type strain is PIP 118(T) ( = DSM 23718(T) = NRRL B-24812(T)).

Jatrophihabitans endophyticus gen. nov., sp. nov., an endophytic actinobacterium isolated from a surface-sterilized stem of Jatropha curcas L.
A short rod-shaped Gram-stain-positive actinobacterium was isolated as an endophyte from the tissues of Jatropha curcas cv. KB27 and was investigated by means of a polyphasic taxonomic approach. An analysis of its 16S rRNA gene sequence indicated that strain S9-650(T) forms an individual line of descent and is related to certain members of the suborder Frankineae, order Actinomycetales (<95 % sequence similarity). Distance-matrix and neighbour-joining analyses set the branching point of the novel isolate between two clades, one being represented by members of the genera Frankia (family Frankiaceae) and Acidothermus (family Acidothermaceae) and the other by members of the genera Geodermatophilus, Blastococcus and Modestobacter (family Geodermatophilaceae). The organism had meso-diaminopimelic acid as the diagnostic diamino acid in the cell-wall peptidoglycan. The acyl type was found to be N-glycolylated. The major menaquinone was MK-9(H4) and the fatty acid profile was characterized by the predominance of iso-C16 : 0, C18 : 1ω9c, anteiso-C17 : 0 and C17 : 1ω8c. The polar lipids comprised diphosphatidylglycerol, an unidentified glycolipid, phospholipids and aminolipids. The G+C content of the genomic DNA was 71.2 mol%. The distinct phylogenetic position and the phenotypic markers that clearly separate the novel organism from all other members of the suborder Frankineae indicate that strain S9-650(T) represents a novel species in a new genus, for which the name Jatrophihabitans endophyticus gen. nov., sp. nov. is proposed. The type strain of the type species is S9-650(T) ( = DSM 45627(T) = KACC 16232(T)).

Streptomyces chlorus sp. nov. and Streptomyces viridis sp. nov., isolated from soil.
Two actinomycete strains, BK125(T) and BK199(T), isolated from a hay meadow soil sample were investigated to determine their taxonomic position using a polyphasic approach. The isolates produced greenish-yellow and light green aerial mycelium on oatmeal agar, respectively. They contained anteiso-C15 : 0, iso-C15 : 0 and C16 : 0 as the major fatty acids, and MK-9 (H6) and MK-9 (H8) as the predominant isoprenoid quinones. Phylogenetic analysis of the 16S rRNA gene sequences showed that the isolates formed distinct phyletic lines towards the periphery of the Streptomyces prasinus subclade. Analysis of DNA-DNA relatedness between the two isolates showed that they belonged to different genomic species. The organisms were also distinguished from one another and from type strains of species classified in the S. prasinus subclade using a combination of genotypic and phenotypic properties. On the basis of these data, it is proposed that the isolates be assigned to the genus Streptomyces as Streptomyces chlorus sp. nov. and Streptomyces viridis sp. nov. with isolates BK125(T) ( = KACC 20902(T) = CGMCC 4.5798(T)) and BK199(T) ( = KACC 21003(T) = CGMCC 4.6824(T)) as the respective type strains.

Friedmanniella flava sp. nov., a soil actinomycete.
A novel actinomycete, strain W6(T), was isolated from a soil sample of Yunnan Province, China. The bacterium was aerobic, non-motile, non-spore-forming and Gram-stain-positive. Genetic, phenotypic and chemical properties of the isolate were studied. 16S rRNA gene sequence data suggested that the novel isolate belonged to the genus Friedmanniella and shared 98.6% sequence similarity with Friedmanniella antarctica DSM 11053(T) and Friedmanniella okinawensis DSM 21744(T), the most closely related species. The cell-wall peptidoglycan contained ll-diaminopimelic acid, and mycolic acids were absent. The main menaquinone was MK-9(H4) and the predominant fatty acids were anteiso-C15:0 and iso-C15:0. The phospholipid profile contained phosphatidylglycerol, phosphatidylinositol, phosphatidylcholine and diphosphatidylglycerol. The DNA G+C content of strain W6(T) was 72 mol%. Strain W6(T) showed 30.0% and 28.5% DNA-DNA relatedness, respectively, to F. antarctica DSM 11053(T) and F. okinawensis DSM 21744(T). The combined genotypic and phenotypic data showed that strain W6(T) should be assigned to the genus Friedmanniella as a representative of a novel species, for which the name Friedmanniella flava sp. nov. is proposed. The type strain is W6(T) ( = CGMCC 4.6856(T) =JCM 17701(T)).

Flaviflexus huanghaiensis gen. nov., sp. nov., an actinobacterium of the family Actinomycetaceae.
Strain H5(T) was isolated from a sediment sample collected from the coastal area of Qingdao, China. The cells were Gram-stain-positive, non-motile, straight or curved rods. The temperature range for growth was 20-37 °C and the pH for growth ranged from 6.5 to 9.0, with optimum growth occurring in the temperature range 28-30 °C and pH range 7.5-8.0. Growth occurred in the presence of 0-6% (w/v) NaCl (optimum, 0-2%). Strain H5(T) had MK-9, MK-9(H2) and MK-9(H4) as the major menaquinones and C18:1ω9c, C16:0, C14:0, C18:0 and C16:1ω9c as major fatty acids. The cell-wall peptidoglycan type was A5α l-Lys-l-Ala-l-Lys-d-Glu. The major polar lipids were phosphatidylglycerol (PG), an unknown phospholipid (PL1) and two unknown phosphoglycolipids (PGL1, PGL2). An unknown phospholipid (PL2) and two unknown glycolipids (GL1, GL2) were present in moderate to minor amounts in the polar lipid profile. The genomic DNA G+C content was 61.8 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain H5(T) represents a novel lineage in the family Actinomycetaceae. On the basis of phenotypic, physiological and molecular characteristics, it is proposed that the novel isolate should be classified as a novel species in a new genus: Flaviflexus huanghaiensis gen. nov., sp. nov., with strain H5(T) ( = DSM 24315(T) =CICC 10486(T)) as the type strain of the type species.

Actinoallomurus acanthiterrae sp. nov., an actinomycete isolated from rhizosphere soil of the mangrove plant Acanthus ilicifolius.
A novel actinobacterium strain, 2614A723(T), was isolated from rhizosphere soil of mangrove plant Acanthus ilicifolius collected at Touyuan, Wenchang, Hainan province, China. A phylogenetic analysis based on 16S rRNA gene sequences indicated that strain 2614A723(T) formed a distinct phyletic line in the genus Actinoallomurus, the 16S rRNA gene tree sharing similarities of 98.35%, 98.07% and 97.86% with Actinoallomurus spadix NBRC 14099(T), Actinoallomurus purpureus TTN02-30(T) and Actinoallomurus luridus TT02-15(T), respectively. Strain 2614A723(T) contained lysine and meso-diaminopimelic acid in the cell wall peptidoglycan and madurose, galactose and xylose in the whole-cell sugars. The predominant menaquinones were MK-9(H4) and MK-9(H6). The major polar phospholipids were phosphatidylglycerol and diphosphatidylglycerol. The predominant fatty acids were iso-C16 : 0 and anteiso-C17 : 0. These chemotaxonomic data confirmed the affiliation of strain 2614A723(T) to the genus Actinoallomurus. It is apparent from the combined phenotypic data, biochemical tests and DNA-DNA hybridization values that strain 2614A723(T) should be classified in the genus Actinoallomurus as a representative of a novel species. The name Actinoallomurus acanthiterrae sp. nov. is proposed with strain 2614A723(T) ( = CCTCC AA 2012001(T) = DSM 45727(T)) as the type strain.

Luteolibacter yonseiensis sp. nov., isolated from activated sludge using algal metabolites.
A Gram-negative, rod-shaped, aerobic bacterial strain, designated EBTL01(T), was isolated from activated sludge by using metabolites of microalgae Ankistrodesmus gracilis SAG278-2. Phylogenetic analyses based on 16S rRNA gene sequence showed that strain EBTL01(T) belongs to the family Verrucomicrobiaceae, class Verrucomicrobiae, and is related most closely to Luteolibacter pohnpeiensis A4T-83(T) (95.5 % sequence similarity) and Luteolibacter algae A5J-41-2(T) (95.2 %). The G+C content of the genomic DNA of strain EBTL01(T) was 56.3 mol% and the menaquinone MK-9 was detected as the predominant quinone. Major fatty acid components were iso-C14 : 0, C16 : 1ω7c and C16 : 0. The amino acids of the cell-wall peptidoglycan contained muramic acid and meso-diaminopimelic acid. These profile results supported the affiliation of strain EBTL01(T) to the genus Luteolibacter. On the other hand, based on chemotaxonomic properties and phenotypic characteristics, strain EBTL01(T) could be clearly differentiated from its phylogenetic neighbours. Therefore, strain EBTL01(T) represents a novel species of the genus Luteolibacter, for which the name Luteolibacter yonseiensis sp. nov. is proposed. The type strain is EBTL01(T) ( = KCTC 23678(T) = JCM 18052(T)).

Streptomyces chiangmaiensis sp. nov. and Streptomyces lannensis sp. nov., isolated from the South-East Asian stingless bee (Tetragonilla collina).
Two novel actinomycetes, strains TA4-1(T) and TA4-8(T,) were isolated from the South-East Asian stingless bee (Tetragonilla collina Smith 1857), collected from Chiang Mai Province, Thailand. The morphological and chemotaxonomic properties of strains TA4-1(T) and TA4-8(T) were consistent with the genus Streptomyces, i.e. the formation of aerial mycelia bearing spiral spore chains, the presence of the ll-isomer of diaminopimelic acid in cell walls, iso- and anteiso-branched fatty acids with carbon chain lengths 14-17 atoms as the major fatty acids and MK-9(H8) as the predominant menaquinone plus minor amounts of MK-9(H6) and MK-9(H10). Analysis of 16S rRNA gene sequences showed that strains TA4-1(T) and TA4-8(T) exhibited 98.8 and 98.1% sequence similarity, respectively, with Streptomyces chromofuscus NRRL B-12175(T) and 98.9% sequence similarity with each other. This study suggested that strains TA4-1(T) and TA4-8(T) were distinct from previously described species of the genus Streptomyces. In addition, the low degrees of DNA-DNA relatedness between the isolates and S. chromofuscus JCM 4354(T) warranted assigning strains TA4-1(T) and TA4-8(T) to two novel species. The names Streptomyces chiangmaiensis sp. nov. (type strain TA4-1(T) = JCM 16577(T) = TISTR 1981(T)) and Streptomyces lannensis sp. nov. (type strain TA4-8(T) = JCM 16578(T) = TISTR 1982(T)) are proposed. The species names indicate the geographical locations where the stingless bees reside.

Acrocarpospora phusangensis sp. nov., isolated from a temperate peat swamp forest soil.
A novel actinomycete, strain PS33-18(T), that formed club-shaped and spherical structures borne on the tip of the aerial mycelia was isolated from a temperate peat swamp forest soil in Phu-Sang National Park, Phayao Province, Thailand. The isolate contained glutamic acid, alanine and meso-diaminopimelic acid in the cell-wall peptidoglycan. The whole-cell sugars of strain PS33-18(T) were glucose, madurose, mannose, rhamnose and ribose. The characteristic phospholipids were phosphatidylethanolamine, phosphatidylmethylethanolamine, hydroxy-phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannosides and ninhydrin-positive phosphoglycolipids. The predominant menaquinone was MK-9(H4). The major cellular fatty acids were C17:1ω8c, iso-C16:0 and C16:0. The G+C content of the genomic DNA of strain PS33-18(T) was 71.0 mol%. Phylogenetic analysis using 16S rRNA gene sequences revealed that strain PS33-18(T) should be classified in the genus Acrocarpospora. The level of similarity between this strain and the closely related species Acrocarpospora macrocephala NBRC 16266(T) was 98.3%, Acrocarpospora pleiomorpha NBRC 16267(T) was 97.9%, Acrocarpospora corrugata NBRC 13972(T) was 97.6%, Herbidospora sakaeratensis NBRC 102641(T) was 97.6% and Planotetraspora kaengkrachanensis NBRC 104272(T) was 97.3%. DNA-DNA hybridization results and physiological and biochemical properties indicated that strain PS33-18(T) could be distinguished readily from its closest phylogenetic relatives. On the basis of these phenotypic and genotypic data, this strain represents a novel species, for which the name Acrocarpospora phusangensis sp. nov. is proposed. The type strain is PS33-18(T) (=BCC 46906(T)=NBRC 108782(T)).

Modestobacter roseus sp. nov., an endophytic actinomycete isolated from the coastal halophyte Salicornia europaea Linn., and emended description of the genus Modestobacter.
A novel actinomycete, designated strain KLBMP 1279(T), was isolated from surface-sterilized roots of a coastal halophyte, Salicornia europaea Linn., collected from Jiangsu Province, in the east of China. The taxonomic status of this organism was established using a polyphasic approach. 16S rRNA gene sequence analysis indicated that strain KLBMP 1279(T) was closely related to Modestobacter marinus 42H12-1(T) (99.5% 16S rRNA gene sequence similarity), Modestobacter versicolor CP153-2(T) (98.4%) and Modestobacter multiseptatus AA-826(T) (97.5%). Chemotaxonomic characteristics were consistent with its assignment to the genus Modestobacter in that the isolate had meso-diaminopimelic acid as the diagnostic diamino acid in the cell wall, MK-9(H4) as major menaquinone and a polar lipid profile containing diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol mannosides, two unknown aminophospholipids and an unknown phospholipid. The predominant fatty acids were iso-C16:0, iso-C15:0 and C17:1ω8c. The DNA G+C content was 71.7 mol%. However, DNA-DNA hybridization assays as well as physiological and biochemical analyses differentiated strain KLBMP 1279(T) from its closest phylogenetic relatives. On the basis of phenotypic, chemotaxonomic and phylogenetic evidence, the isolate KLBMP 1279(T) represents a novel species of the genus Modestobacter, for which the name Modestobacter roseus sp. nov. is proposed; the type strain is KLBMP 1279(T) (=KCTC 19887(T)=NBRC 108673(T)=DSM 45764(T)). An emended description of the genus Modestobacter is also proposed.

Thalassolituus marinus sp. nov., a hydrocarbon-utilizing marine bacterium.
Gram-negative strains, motile by a single polar flagellum, non-pigmented and with a curved rod-shaped morphology, designated IMCC1826(T) and IMCC1883, were isolated from a surface seawater sample from the Yellow Sea. The two strains shared 99.9% 16S rRNA gene sequence similarity and showed 92% DNA-DNA relatedness, suggesting that they belonged to the same genomic species. Phylogenetic analysis based on 16S rRNA gene sequences showed that the two isolates were related most closely to the type strain of Thalassolituus oleivorans with a sequence similarity of 96.4% and formed a robust phyletic lineage with T. oleivorans. DNA-DNA relatedness between the two strains and T. oleivorans DSM 14913(T) was 8.7-11.6%. A putative alkane hydroxylase (alkB) gene was detected in strain IMCC1826(T) by PCR, but the amino acid sequence of the gene was distantly related to that of the AlkB homologue of T. oleivorans DSM 14913(T). As expected from the presence of the alkB gene, the new strains utilized n-tetradecane and n-hexadecane as a carbon source. The DNA G+C content was 54.6-56.0 mol% and the main isoprenoid quinone detected was Q-9. Polar lipids of strain IMCC1826(T) included diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and amino-group-containing lipids. On the basis of taxonomic data obtained in this study, strains IMCC1826(T) and IMCC1883 represent a novel species of the genus Thalassolituus, for which the name Thalassolituus marinus sp. nov. is proposed, with IMCC1826(T) (=KCTC 23084(T)=NBRC 107590(T)) as the type strain.

Geodermatophilus telluris sp. nov., an actinomycete isolated from Saharan desert sand.
A novel Gram-positive, multiloculated thalli-forming, aerobic, actinobacterial strain, CF9/1/1(T), was isolated in 2007 during environmental screening for xerophilic fungi in arid desert soil from the Sahara desert, Chad. The isolate grew best at a temperature range of 20-35 °C and at pH 6.0-8.5 and with 0-4% (w/v) NaCl, forming black-coloured and irregular colonies on GYM agar. Chemotaxonomic and molecular characteristics of the isolate matched those described for members of the genus Geodermatophilus. The DNA G+C content of the novel strain was 75.4 mol%. The peptidoglycan contained meso-diaminopimelic acid as a diagnostic diamino acid. The main phospholipids were diphosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol, a not yet structurally identified aminophospholipid and a small amount of phosphatidylglycerol; MK-9(H4) was identified as the dominant menaquinone and galactose was a diagnostic sugar. The major cellular fatty acids were branched-chain saturated acids: iso-C16:0 and iso-C15:0. The 16S rRNA gene sequence of the isolate showed 94.6-97.0% sequence similarities with those of five members of the genus: Geodermatophilus ruber DSM 45317(T) (94.6%), Geodermatophilus obscurus DSM 43160(T) (94.8%), Geodermatophilus siccatus DSM 45419(T) (96.2%), Geodermatophilus nigrescens DSM 45408(T) (96.7%) and Geodermatophilus arenarius DSM 45418(T) (97.0%). Based on the evidence from this polyphasic taxonomic study, a novel species, Geodermatophilus telluris sp. nov., is proposed; the type strain is CF9/1/1(T) (=DSM 45421(T)=CCUG 62764(T)).

Description of Tersicoccus phoenicis gen. nov., sp. nov. isolated from spacecraft assembly clean room environments.
Two strains of aerobic, non-motile, Gram-reaction-positive cocci were independently isolated from geographically distinct spacecraft assembly clean room facilities (Kennedy Space Center, Florida, USA and Centre Spatial Guyanais, Kourou, French Guiana). A polyphasic study was carried out to delineate the taxonomic identity of these two isolates (1P05MA(T) and KO_PS43). The 16S rRNA gene sequences exhibited a high similarity when compared to each other (100 %) and lower than 96.7 % relatedness with Arthrobacter crystallopoietes ATCC 15481(T), Arthrobacter luteolus ATCC BAA-272(T), Arthrobacter tumbae DSM 16406(T) and Arthrobacter subterraneus DSM 17585(T). In contrast with previously described Arthrobacter species, the novel isolates maintained their coccidal morphology throughout their growth and did not exhibit the rod-coccus life cycle typically observed in nearly all Arthrobacter species, except A. agilis. The distinct taxonomic identity of the novel isolates was confirmed based on their unique cell-wall peptidoglycan type (A.11.20; Lys-Ser-Ala2) and polar lipid profile (presence of phosphatidylglycerol, diphosphatidylglycerol, phosphatidylinositol, an unknown phospholipid and two unknown glycolipids). The G+C content of the genomic DNA was 70.6 mol%. The novel strains revealed MK-9(H2) and MK-8(H2) as dominant menaquinones and exhibited fatty acid profiles consisting of major amounts of anteiso-C15 : 0 and anteiso-C17 : 0 and moderate amounts of iso-C15 : 0 discriminating them again from closely related Arthrobacter species. Based on these observations, the authors propose that strains 1P05MA(T) and KO_PS43 be assigned into a separate genus Tersicoccus gen. nov. For this new taxon, comprising strains 1P05MA(T) and KO_PS43, we propose the name Tersicoccus phoenicis gen. nov., sp. nov. (the type species of Tersicoccus), represented by the type strain Tersicoccus phoenicis 1P05MA(T) ( = NRRL B-59547(T) = DSM 30849(T)).

Streptosporangium sandarakinum sp. nov.
A Gram-positive, non-spore-forming bacterium (GW-12028(T)) of unknown origin showing filamentous growth and producing spherical sporangia was studied for its taxonomic allocation. The 16S rRNA gene sequence analysis and subsequent similarity studies showed that strain GW-12028(T) belongs to the genus Streptosporangium, and is most closely related to Streptosporangium pseudovulgare DSM 43181(T) (99.9 %) and Streptosporangium nondiastaticum DSM 43848(T) (99.6 %) and more distantly related to Streptosporangium fragile IFO 14311(T) (98.4 %) and other species of the genus Streptosporangium (95.8 to 98 %). Chemotaxonomic analyses showed that the peptidoglycan diamino acid was meso-diaminopimelic acid. Whole-cell hydrolysates contained madurose as the diagnostic sugar and exhibited a quinone system that contained predominantly menaquinones with nine isoprenoic units in the side chain [MK-9, MK-9(H2), MK-9(H4)]. The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylglycerol, phoshatidylethanolamine, hydroxyphosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol-mannosides, four unidentified glycolipids, a phospholipid and an aminolipid. The polyamine pattern contained the major compounds spermine and spermidine. The major fatty acids were 10-methyl C17 : 0, iso-C16 : 0 and C15 : 0. These chemotaxonomic traits are common to other species of the genus Streptosporangium. DNA-DNA hybridizations and physiological and biochemical tests in comparison with the type strains of the most closely related species, S. nondiastaticum and S. pseudovulgare, allowed genotypic and phenotypic differentiation of strain GW-12028(T). This strain represents a novel species, for which we propose the name Streptosporangium sandarakinum sp. nov., with the type strain GW-12028(T) ( = LMG 27062(T) = DSM 45763(T)).

Geodermatophilus soli sp. nov. and Geodermatophilus terrae sp. nov., two actinobacteria isolated from grass soil.
Two strains, PB34(T) and PB261(T), were isolated from grass soil sampled in Daejeon, Republic of Korea. Comparative 16S rRNA gene sequence studies showed the two bacteria to be clearly affiliated with the phylum Actinobacteria and most closely related to the genus Geodermatophilus, showing 16S rRNA gene sequence similarities to the type strains of species of the genus Geodermatophilus of 95.0-96.3 % and sharing 98.5 % similarity between the two strains. The two strains were Gram-stain-positive, aerobic, motile and rod-shaped bacteria. The peptidoglycan contained meso-diaminopimelic acid as the diagnostic diamino acid. The predominant menaquinones were MK-9(H4) and MK-9(H0). The major fatty acids were iso-C15 : 0, iso-C16 : 0, iso-C17 : 0 and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) for strain PB34(T) and iso-C14 : 0, iso-C15 : 0, iso-C16 : 0 and C16 : 0 for strain PB261(T). The G+C contents of the genomic DNA of strains PB34(T) and PB261(T) were 73.2 mol% and 74.1 mol%, respectively. Thus, based on the evidence of a polyphasic study, it is proposed that strains PB34(T) and PB261(T) represent two novel species, for which the names Geodermatophilus soli sp. nov. (type strain PB34(T) = KCTC 19880(T) = JCM 17785(T)) and Geodermatophilus terrae sp. nov. (type strain PB261(T) = KCTC 19881(T) = JCM 17786(T)) are proposed.

Planobispora siamensis sp. nov., isolated from soil.
A novel actinomycete strain, A-T 4600(T), which developed cylindrical sporangia containing a longitudinal pair of motile spores forming singly or in bundles on short ramifications of the aerial mycelium, was isolated from soil collected from an evergreen forest in Thailand. The cell-wall peptidoglycan contained meso-diaminopimelic acid. The whole-cell sugars contained ribose, madurose, mannose and glucose. The predominant menaquinones were MK-9(H2). Mycolic acids were not detected. The diagnostic phospholipids were phosphatidylethanolamine, phosphatidylmethylethanolamine, phosphatidylinositol, phosphatidylglycerol, phosphatidylinositol mannoside, diphosphatidylglycerol and aminophosphoglycolipid. The predominant cellular fatty acids were unsaturated C17 : 1, C18 : 1, saturated C16 : 0, and C17 : 0. The G+C content of the DNA was 70.8 mol%. Phenotypic and chemotaxonomic analyses showed that the isolate had the typical characteristics of members of the genus Planobispora. Furthermore, 16S rRNA gene sequence analysis also indicated that this strain belonged to the genus Planobispora but as a putative novel species. DNA-DNA relatedness values that differentiate the isolate from previously described members of the genus Planobispora were significantly below 70 %. Following an evaluation of phenotypic, chemotaxonomic and genotypic studies, it is proposed that the isolate represents a novel species, Planobispora siamensis sp. nov.; the type strain is A-T 4600(T) ( = BCC 39469(T) = NBRC 107568(T)).

Paraoerskovia sediminicola sp. nov., an actinobacterium isolated from sea sediment, and emended description of the genus Paraoerskovia.
A novel Gram-stain-positive actinobacterium, designated H25-14(T), was isolated from a sea sediment sample, and its taxonomic position was investigated by a polyphasic approach. The peptidoglycan type of strain H25-14(T) was A4α and lysine was the diagnostic diamino acid of the peptidoglycan. The predominant menaquinone was MK-9(H4) and the major fatty acids were anteiso-C15 : 0 and iso-C15 : 0. The DNA G+C content was 73.2 mol%. Phylogenetic analysis based on 16S rRNA gene sequence comparisons revealed that strain H25-14(T) was closely related to Paraoerskovia marina NBRC 104352(T) (98.3 %). However, DNA-DNA hybridization data and phenotypic characteristics revealed that strain H25-14(T) differed from P. marina NBRC 104352(T). Therefore, strain H25-14(T) represents a novel species of the genus Paraoerskovia, for which the name Paraoerskovia sediminicola sp. nov. is proposed. The type strain is H25-14(T) ( = NBRC 108565(T) = DSM 25477(T)). An emended description of the genus Paraoerskovia is also proposed.

Streptomyces chilikensis sp. nov., a halophilic streptomycete isolated from brackish water sediment.
A novel actinobacterial strain, designated RC 1830(T), was isolated from the sediment of estuarine coastal brackish water lagoon of Chilika Lake, in Khurdha district of Odisha, India, and characterized using a polyphasic approach. Strain RC 1830(T) was halophilic and alkali-tolerant and found to hydrolyse chitin, starch, tributyrin, lecithin, Tween 80, cellulose, gelatin and casein. The diagnostic presence of ll-diaminopimelic acid, iso-C15 : 0, anteiso-C15 : 0, iso-C16 : 0, C16 : 0, iso-C17 : 0, anteiso-C17 : 0 as major cellular fatty acids and MK-9(H4 and H6) as major menaquinones noticeably associated the strain to the genus Streptomyces. After comparison and analysis of the near complete 16S rRNA gene sequence with representative strains of other streptomycetes, it was evident that strain RC 1830(T) belonged to the genus Streptomyces, and exhibited the highest sequence similarities of 99.53 %, 99.25 %, 99.11 %, 99.10 % and 99. 06 % to Streptomyces fragilis DSM 40044(T), Streptomyces coelicoflavus NBRC 15399(T), Streptomyces flaveolus NBRC 3715(T), Streptomyces lavenduligrisesus NBRC 13405(T) and Streptomyces eurythermus ATCC 14975(T), respectively. Reconstruction of a phylogenetic tree for the genus Streptomyces revealed that strain RC 1830(T) formed a distinct phyletic line and clustered with its most closely related neighbour S. fragilis DSM 40044(T). The DNA-DNA relatedness values between strain RC 1830(T) and the most closely related type strain S. fragilis DSM 40044(T) were determined to be 17.7 ± 4.55 %. Additionally, morphological, biochemical and physiological tests were able to distinguish the strain from the most closely related type strain S. fragilis DSM 40044(T) and other closely related neighbours, S. coelicoflavus DSM 41471(T) and Streptomyces flaveolus DSM 40061(T). Based on a range of phenotypic and genotypic properties, strain RC 1830(T) is suggested to represent a novel species of the genus Streptomyces for which the name Streptomyces chilikensis sp. nov. is proposed. The type strain is RC 1830(T) ( = JCM 18411(T) = DSM 42072(T)).

Actinokineospora bangkokensis sp. nov., isolated from rhizospheric soil.
A novel actinomycete, strain 44EHW(T), was isolated from rhizospheric soil under an Elephant ear plant (Colocasia esculenta) in Bangkok, Thailand. Strain 44EHW(T) produced long branching hyphae and abundant aerial mycelia with chains of rod-shaped spores. Whole-cell hydrolysates contained galactose, glucose, arabinose, ribose, mannose and rhamnose as diagnostic sugars. meso-Diaminopimelic acid was the diamino acid and glycine, alanine and glutamic acid were present in the cell-wall peptidoglycan with the acyl type of the peptidoglycan being acetyl. Phospholipids consisted of phosphatidylethanolamine, phosphatidylethanolamine with hydroxy fatty acids and diphosphatidylglycerol, as well as other unknown phospholipids; however, no mycolic acids were detected. The predominant menaquinone observed was MK-9(H4) and major fatty acids were iso-C16 : 0 and 2-OH iso-C16 : 0. The G+C content of genomic DNA was 74 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that this isolate was most similar to Actinokineospora enzanensis NBRC 16517(T). However, DNA-DNA hybridization revealed a low relatedness between this isolate and A. enzanensis NBRC 16517(T), indicating that this isolate represented a novel species in the genus Actinokineospora. On the basis of 16S rRNA gene sequence analysis, phenotypic characteristics and DNA-DNA hybridization data, we propose that strain 44EHW(T) represents a novel species in the genus Actinokineospora, Actinokineospora bangkokensis. The type strain is 44EHW(T) ( = BCC 53155(T) = NBRC 108932(T)).

Pseudoclavibacter caeni sp. nov., isolated from sludge of a sewage disposal plant.
A Gram-positive, strictly aerobic, rod-shaped, non-motile bacterial strain, designated MJ28T, was isolated from a sludge sample from the Daejeon sewage disposal plant in South Korea. A polyphasic approach was applied to study the taxonomic position of strain MJ28T. Strain MJ28T showed highest 16S rRNA gene sequence similarity to Pseudoclavibacter soli KP02T (95.2 %). Levels of 16S rRNA gene sequence similarity to the type strains of other Pseudoclavibacter species were less than 94.0 %. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain MJ28T belonged to the clade formed by members of the genus Pseudoclavibacter in the family Microbacteriaceae.

The G+C content of the genomic DNA was 71.8 mol%. The chemotaxonomic data [MK-9(H6) and MK-9(H8) as the major menaquinones; ll-diaminopimelic acid as a component of the cell-wall peptidoglycan; ribose, xylose, mannose and glucose as the major cell-wall sugars; and anteiso-C15:0, iso-C15:0, iso-C17:0, anteiso-C17:0 and C16:0 as the major fatty acids] supported the affiliation of strain Gsoil 519T to the genus Streptomyces. The physiological and biochemical characteristics and the low level of DNA-DNA relatedness differentiated the isolate genotypically and phenotypically from recognized members of the genus Streptomyces. The isolate, therefore, represents a novel species, for which the name Streptomyces panacagri sp. nov. is proposed, with Gsoil 519T (=KCTC 19139T=DSM 41871T) as the type strain.

Corynebacterium deserti sp. nov., isolated from desert sand.
A novel coryneform bacterium, designated strain GIMN1.010T, was isolated from a sand sample collected in the desert in the west of China. Cells were Gram-stain-positive, non-spore-forming, catalase-positive, irregular rods. Comparative 16S rRNA gene sequence analysis demonstrated that strain GIMN1.010T belonged to the genus Corynebacterium and was related closely to Corynebacterium glutamicum ATCC 13032T (98.4 % similarity). However, the level of DNA-DNA relatedness between strain GIMN1.010T and C. glutamicum ATCC 13032T was only 22.4±1.72 %, showing that strain GIMN1.010T represented a genomic species distinct from C. glutamicum. On the basis of phenotypic and phylogenetic data, strain GIMN1.010T is considered to represent a novel species of the genus Corynebacterium, for which the name Corynebacterium deserti sp. nov. is proposed.

A novel aerobic streptomycete, strain SCSIO 01248T, was isolated from a sample of deep-sea sediment collected from the northern South China Sea, at a depth of 1632 m. This isolate formed yellow-white substrate mycelium and grey-white aerial hyphae. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain SCSIO 01248T was most closely related to Streptomyces radiopugnans R97T (98.8 % sequence similarity), S. macrosporus NBRC 14748T (97.5 %) and S. megasporus NBRC 14749T (97.3 %). The novel strain could, however, be readily differentiated from S. radiopugnans DSM 41901T on the basis of some physiological and cellular chemical characteristics; the level of DNA-DNA relatedness between these two strains was only 40 %.

Streptomyces gramineus sp. nov., an antibiotic-producing actinobacterium isolated from bamboo (Sasa borealis) rhizosphere soil.
Two actinobacterial strains, JR-43T and JR-4, were isolated from bamboo (Sasa borealis) rhizosphere soil. The isolates produced grey aerial mycelium and a yellow soluble pigment on ISP 4. Microscopic observation revealed that strains JR-43T and JR-4 produced rectiflexibiles spore chains with spiny surfaces. Both isolates had antibacterial activity against plant-pathogenic bacteria, such as Xanthomonas campestris LMG 568T and Xanthomonas axonopodis pv. vesicatoria LMG 905. The isolates contained iso-C14:0, iso-C15:0, anteiso-C15:0 and iso-C16:0 as the major fatty acids and MK-9(H6) and MK-9(H8) as the major isoprenoid quinones. Phylogenetic analysis of the 16S rRNA gene sequences of strains JR-43T and JR-4 showed that they grouped within Streptomyces cluster II and had highest sequence similarity to Streptomyces seoulensis NBRC 16668T and Streptomyces recifensis NBRC 12813T (both 98.2 % 16S rRNA gene sequence similarity). DNA-DNA relatedness between strain JR-43T and S. seoulensis NBRC 16668T and S. recifensis NBRC 12813T ranged from 31.42 to 42.92 %. Based on DNA-DNA relatedness and morphological and phenotypic data, strains JR-43T and JR-4 could be distinguished from the type strains of phylogenetically related species. They are therefore considered to represent a novel species of the genus Streptomyces, for which the name Streptomyces gramineus sp. nov. is proposed. The type strain is JR-43T (=KACC 15079T=NBRC 107863T). Strain JR-4 (=KACC 15078= NBRC 107864) is a reference strain [corrected].

Isoptericola nanjingensis sp. nov., a mineral-weathering bacterium.
A Gram-positive-staining, non-motile, rod- or coccoid-shaped actinobacterium, designated strain H17T, was isolated from a soil sample from Nanjing, Jiangsu Province, PR China. The organism grew optimally at 30 °C, pH 7.0 and with 3 % NaCl (w/v). Strain H17T contained L-Lys-D-Asp as the cell-wall peptidoglycan type and galactose, xylose and mannose as the whole-cell sugars. The major fatty acids were anteiso-C15:0 and iso-C15:0. The total polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phospholipids, phosphatidylinositol, phosphoglycolipid, one unidentified glycolipid and one unidentified lipid. The menaquinone was MK9(H4). Mycolic acids were not detected. The DNA G+C content was 72.4 mol%. Phylogenetic analysis of this strain based on 16S rRNA gene sequences revealed 97.8-99.6 % similarity to recognized species of the genus Isoptericola. The low level of DNA-DNA relatedness to other species of the genus Isoptericola and the many phenotypic properties that distinguished strain H17T from recognized species of this genus demonstrated that isolate H17T should be classified as representing a novel species of the genus Isoptericola. The name Isoptericola nanjingensis sp. nov. is proposed for this novel species. The type strain is H17T (=DSM 24300T=CCTCC AB 2011005T).

Streptomyces staurosporininus sp. nov., a staurosporine-producing actinomycete.
The taxonomic position of a staurosporine-producing actinomycete isolated from a hay meadow soil was determined using a polyphasic approach. The organism had chemical and morphological characteristics consistent with its classification in the genus Streptomyces and formed a distinct branch between the Streptomyces lydicus and Streptomyces noursei clades in the 16S rRNA Streptomyces gene tree. DNA-DNA relatedness values between the isolate and its nearest phylogenetic neighbours, namely Streptomyces lydicus NBRC 13058T and Streptomyces chattanoogensis NBRC 12754T, were 53 % and 40 %, respectively. The isolate was also readily distinguished from the type strains of these species using a combination of morphological and other phenotypic properties. On the basis of these results, it is proposed that isolate BK179T (=KACC 20912T=NRRL B-24850T) be classified as the type strain of Streptomyces staurosporininus sp. nov.

A novel actinobacterial strain, A4029T, isolated from arid soil of Abuja, Nigeria, and provisionally assigned to the genus Actinoplanes, was subjected to a polyphasic taxonomic study. 16S rRNA gene sequence similarity studies showed that strain A4029T belonged to the genus Actinoplanes, being most closely related to Actinoplanes brasiliensis DSM 43805T (98.9 %) and Actinoplanes deccanensis DSM 43806T (98.0 %); similarity to other type strains of the genus Actinoplanes ranged from 96.2 to 97.9 %. Chemotaxonomic data [major menaquinone MK-9(H4); major polar lipids phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol and phosphatidylinositol; characteristic sugars arabinose and xylose; major fatty acids iso-C15:0, anteiso-C15:0, iso-C16:0, C17:1ω9c and iso-C14:0] confirmed the affiliation of strain A4029T to the genus Actinoplanes. The results of DNA-DNA hybridizations and phylogenetic analysis, together with phenotypic and biochemical test data, allowed strain A4029T to be differentiated from strains of other Actinoplanes species. Therefore, strain A4029T represents a novel species, for which the name Actinoplanes abujensis sp. nov. is proposed, with A4029T (=DSM 45518T=NRRL B-24835T=KCTC 19984T) as the type strain.

Actinomadura rupiterrae sp. nov., isolated from cliff soil.
A novel actinomycete strain, designated CS5-AC15T, was isolated from a soil sample collected from a cliff on Mara Island, Jeju, Republic of Korea, and subjected to a polyphasic taxonomic analysis. The isolate produced well-developed, yellow substrate mycelium and white aerial mycelium that differentiated into straight or flexuous chains of smooth-surfaced spores. 16S rRNA gene sequence analyses showed that the organism belonged to the family Thermomonosporaceae and formed a tight cluster with the type strain of Actinomadura oligospora (97.4 % sequence similarity). Chemotaxonomic characteristics were consistent with its assignment to the genus Actinomadura in that the isolate had meso-diaminopimelic acid as the diagnostic diamino acid in the cell wall, madurose as the characteristic sugar, N-acetyl type of murein in the peptidoglycan, MK-9(H6) and MK-9(H8) as major menaquinones and a polar lipid profile containing diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol and unknown phospholipids. Mycolic acids were not detected. The predominant fatty acids were C16:0, C18:1ω9c and iso-C16:0. The DNA G+C content was 70.9 mol%. DNA relatedness of strain CS5-AC15T and A. oligospora JCM 10648T was 37.9±0.7 %. On the basis of the phenotypic, phylogenetic and DNA-DNA hybridization data, strain CS5-AC15T is assigned to a novel species of the genus Actinomadura, for which the name Actinomadura rupiterrae sp. nov. is proposed (type strain CS5-AC15T=KCTC 19559T=DSM 45251T).

A Gram-positive, aerobic, non-motile actinomycete, strain MN08-A0264(T), was isolated from soil sampled in Mongolia. The isolate formed pale to moderate yellowish brown colonies and branched substrate mycelium. On the basis of 16S rRNA gene sequence analysis, strain MN08-A0264(T) belonged to the genus Cryptosporangium and exhibited 97.9 % 16S rRNA gene sequence similarity with Cryptosporangium aurantiacum IMSNU 22120(T), 97.7 % with C. minutisporangium IFO 15962(T), 97.2 % with C. arvum IFO 15965(T) and 96.8 % with C. japonicum IFO 15966(T). The allocation of the isolate to the genus Cryptosporangium was supported by chemotaxonomic data: menaquinone MK-9(H(6)) with minor amounts of MK-9(H(8)) and MK-9(H(4)), major amounts of iso-C(16 : 0), C(18 : 1)9c and C(17 : 0) 10-methyl, a polar lipid profile comprising phosphatidylethanolamine, phosphatidylinositol, diphosphatidylglycerol, phosphatidylglycerol and glycolipids, and whole-cell sugars glucose, galactose, acofriose (3-0 methylrhamnose), mannose, ribose, arabinose, xylose and rhamnose (trace). DNA-DNA relatedness (5-20 %) differentiated the isolate from its closest neighbours. The physiological and biochemical tests allowed the differentiation of strain MN08-A0264(T) from members of the genus Cryptosporangium. Thus, strain MN08-A0264(T) represents a novel species, for which the name Cryptosporangium mongoliense sp. nov. is proposed. The type strain is MN08-A0264(T) ( = NBRC 105887(T) = VTCC D9-27(T)).

Streptomyces sanyensis sp. nov., isolated from mangrove sediment.
A novel strain, 219820(T), whose metabolites were found to be active against tumour cells, was isolated and characterized. The isolate belonged to the genus Streptomyces and had white to grey aerial mycelium and long chains of smooth spores in the aerial mycelium. A phylogenetic tree based on 16S rRNA gene sequences showed that strain 219820(T) had highest similarity to members of the genus Streptomyces and was most closely, albeit loosely, associated with Streptomyces crystallinus NBRC 15401(T) (98.624 % similarity), Streptomyces melanogenes NBRC 12890(T) (98.565 %) and Streptomyces noboritoensis NBRC 13065(T) (98.564 %). However, DNA-DNA relatedness and phenotypic data readily distinguished strain 219820(T) from these phylogenetically related type strains. It is evident from the combination of genotypic and phenotypic data that strain 219820(T) represents a novel species of the genus Streptomyces, for which the name Streptomyces sanyensis sp. nov. is proposed; the type strain is 219820(T) ( = CGMCC 4.5626(T) = DSM 42014(T)).

Three Gram-positive, NaCl-requiring actinobacteria were isolated from a marine sponge, Haliclona sp., collected from the coast of Tateyama City, Japan. Comparison of 16S rRNA gene sequences indicated that these strains represent novel members of the genus Streptomyces, exhibiting low 16S rRNA gene sequence similarities of 98.3-97.4 % with recognized members of the genus. The cell hydrolysates contained the LL-isomer of diaminopimelic acid and the predominant quinones were MK-9 (H(6) and/or H(8)). The DNA G+C contents were in the range 72-75mol%. A polyphasic study of the strains and comparison of the characters with related species of the genus show that these strains represent three novel species of the genus Streptomyces. Therefore, the names Streptomyces tateyamensis sp. nov., Streptomyces haliclonae sp. nov. and Streptomyces marinus sp. nov. are proposed for strains Sp080513SC-30(T) (=NBRC 105048(T) =DSM 41969(T)), Sp080513SC-31(T) (=NBRC 105049(T) =DSM 41970(T)) and Sp080513GE-26(T) (=NBRC 105047(T) =DSM 41968(T)), respectively.

Effects of UV pretreatment on microbial community structure and metabolic characteristics in a subsequent biofilter treating gaseous chlorobenzene.
To provide insight into effects of UV pretreatment on microorganisms in subsequent biofilters, the changes of microbial community structure and metabolic characteristics of biofilters with (UV-BF) and without (BF) UV pretreatment were studied. The respiratory quinone and BIOLOG methods were used to analyze microbial community structure and metabolic characteristics, respectively. The results indicated the quinone profiles, the species of dominant quinone and its molar fraction of the biofilm in both biofilters showed different behaviors. Ubiquinones-8 and menaquinone-9(H(2)) was the dominant quinones in BF and UV-BF processes, respectively. The dissimilarity index of two biofilters markedly increased to nearly 60 after turning on the UV lamp. The microbial samples from UV-BF process showed higher metabolic activities of 0.040 cm(-1) h(-1) than 0.028 cm(-1) h(-1) in BF process. Moreover, the microorganisms in both biofilters demonstrated distinct metabolic characteristics. Further, the performance of biofilters showed good correlation with microbial community structure and metabolic characteristics.

The glycan moiety of the murein contained acetyl residues. The predominant menaquinone was MK-9(H2); mycolic acids were not detected. The genomic DNA G+C content was 73.3 mol%. The major cellular fatty acid was anteiso-C(15 : 0) (81.42 % of the total). Strain KKD096(T) was assigned to the genus Kineococcus on the basis of 16S rRNA gene sequence analysis; it was most closely related to Kineococcus radiotolerans DSM 14245(T) (97.1 % similarity). DNA-DNA hybridization revealed 39.4 % relatedness between these two taxa. On the basis of the genotypic and phenotypic data presented, strain KKD096(T) is considered to represent a novel species of the genus Kineococcus, for which the name Kineococcus gynurae sp. nov. is proposed. The type strain is KKD096(T) (=TISTR 1856(T)=NRRL B-24568(T)=BCC 26245(T)=NBRC 103943(T)).

Amycolatopsis taiwanensis sp. nov., from soil.
An actinomycete strain (0345M-7(T)) was isolated from a soil sample from Yilan county, Taiwan. The isolate displayed substrate mycelia, upon which were borne short spore chains. The spore chains were composed of non-motile, smooth-surfaced, oval spores. Strain 0345M-7(T) had meso-diaminopimelic acid in its peptidoglycan. Whole-cell sugars were galactose, glucose, arabinose and ribose. The only phospholipid found was phosphatidylethanolamine. The predominant menaquinone was MK-9(H(4)). Mycolic acids were not detected. Major cellular fatty acids were iso-C(16 : 0) (38.1 %) and C(17 : 1) (25.4 %). The DNA G+C content of strain 0345M-7(T) was 68.9 mol%. On the basis of phenotypic and genotypic data, it is proposed that strain 0345M-7(T) (=BCRC 16802(T)=KCTC 19116(T)) should be classified as the type strain of a novel species of the genus Amycolatopsis, Amycolatopsis taiwanensis sp. nov.

Brooklawnia cerclae gen. nov., sp. nov., a propionate-forming bacterium isolated from chlorosolvent-contaminated groundwater.
Two novel facultatively anaerobic bacterial strains, BL-34(T) and BL-35, isolated from groundwater contaminated by a mixture of chlorosolvents were characterized using a polyphasic approach. The two strains exhibited essentially identical taxonomic features except for a vitamin B(12) requirement by strain BL-35 for optimal growth. Phylogenetically, the isolates were affiliated with members of the family Propionibacteriaceae and were placed in a phylogenetic branch adjacent to, but distinct from, those of the genera Propionimicrobium, Propionibacterium, Luteococcus, Propioniferax and Tessaracoccus. The cells of the novel strains were Gram-positive, non-motile, non-spore-forming pleomorphic rods. They produced catalase but not oxidase, and nitrate reduction did not occur in peptone/yeast extract/glucose medium. Propionate and acetate were the predominant products of glucose fermentation. Fermentation occurred in the presence of 1,2-dichloroethane and 1,1,2-trichloroethane at concentrations up to at least 9.8 mM. The genomic DNA G+C content was 67.5-67.9 mol%. Menaquinone MK-9(H(4)) was the predominant respiratory quinone and meso-diaminopimelic acid was present in the cell-wall peptidoglycan layer. The major cellular fatty acids were C(15 : 0) and anteiso-C(15 : 0). On the basis of the results obtained in this study, strains BL-34(T) and BL-35 should be classified within a novel taxon, for which the name Brooklawnia cerclae gen. nov., sp. nov. is proposed. The type strain of Brooklawnia cerclae is BL-34(T) (=LMG 23248(T)=NRRL B-41418(T)). An additional strain, BL-35 (=LMG 23249=NRRL B-41419), was also characterized.

Planotetraspora silvatica sp. nov. and emended description of the genus Planotetraspora.
An actinomycete that developed sporangia containing four spores in a single row at the ends of short sporangiophores on branched aerial hyphae was isolated from subtropical forest soil. The isolate contained menaquinone MK-9(H(4)), glutamic acid, alanine and meso-diaminopimelic acid as cell-wall amino acids and madurose in the whole-cell hydrolysate. The 16S rRNA gene sequence indicated that the isolate formed a monophyletic cluster with Planotetraspora mira. On the basis of morphological and chemotaxonomic characteristics, phylogenetic analysis and DNA-DNA relatedness data, a novel species of the genus Planotetraspora is proposed, Planotetraspora silvatica sp. nov. (type strain, TT 00-51(T)=NBRC 100141(T)=DSM 44746(T)).

Jonesia quinghaiensis sp. nov., a new member of the suborder Micrococcineae.
A coryneform strain isolated from soda lake mud in China corresponded in chemotaxonomic characteristics such as peptidoglycan type A4alpha l-lys-l-ser-d-Glu and major menaquinone MK-9, as well as in its DNA base composition (57 mol% G+C), to its phylogenetic neighbour Jonesia denitrificans. Differences in phenotypic characteristics and the phylogenetic distance (96.6 % 16S rRNA gene sequence similarity) from J. denitrificans justify the proposal of a second species of the genus Jonesia, Jonesia quinghaiensis sp. nov., with the type strain QH3A7(T) (=DSM 15701(T)=CGMCC 1.3459(T)).

Differential lipoprotein transport pathways of K-vitamins in healthy subjects.
Vitamin K is a group name for K1 (phylloquinone) and K2 (menaquinones). Both forms contribute to the tissue vitamin K status. Following intestinal absorption, the serum transport of these lipophilic compounds to their target tissues takes place via lipoproteins. In previous studies we have found that K1 is preferentially accumulated in the liver, whereas menaquinones have a more widespread distribution pattern. Here we have tested whether these differences may be explained by the different liposolubility of the various K-vitamers, resulting in their association with different lipoprotein particles. Six healthy male volunteers received a mixture containing 2 micromol of each of three K vitamers (K1, MK-4, and MK-9) dissolved in corn oil. Blood was obtained at baseline and at different time intervals after intake for the measurement of vitamin K in serum and in the lipoprotein fractions. During the first 4 h after intake all K-vitamins were found to be associated predominantly with the triacylglycerol-rich lipoprotein (TGRLP) fraction. Since the TGRLP fraction is mainly cleared by the liver, this suggests that initially most of the K-vitamins are transported to the liver. In contrast to K1, however, both menaquinones investigated were also found in TGRLP and low-density lipoprotein, whereas MK-4 was even present in high-density lipoprotein. This explains why menaquinones may have a different distribution profile and suggests a relatively large impact of menaquinones on extra-hepatic vitamin K status than generally assumed. Moreover, the very long half-life time of MK-9 in the circulation indicates that it may form a more constant source of vitamin K than are either K1 or MK-4.

Induction of prothrombin synthesis by K-vitamins compared in vitamin K-deficient and in brodifacoum-treated rats.
Vitamin K is a group name for a number of prenylated 2-methyl-1,4-naphtoquinones, which may differ in their ability to function as a cofactor for prothrombin biosynthesis. To quantify the bioactivity of different forms of vitamin K, two experimental animal systems are frequently used: vitamin K-deficient rats and anticoagulated rats. In this paper both models are compared, and it is shown that the results obtained depend on the model used. The main reason for this discrepancy is the difference in recycling of vitamin K-epoxide, which results in a 500 times higher vitamin K requirement in anticoagulated rats. Absorption and hepatic accumulation of long chain menaquinones seem to be restricted to a maximum, whereas also the lipophilic nature of long chain menaquinones may hamper the quinone-quinol reduction in anticoagulated animals. If these data may be extrapolated to patients, food items rich in K1 and MK-4 would be expected to influence the stability of oral anticoagulation to a much larger extent than food items primarily containing higher menaquinones.

Bioavailability of phylloquinone and menaquinones after oral and colorectal administration in vitamin K-deficient rats.
Rats were made vitamin K-deficient by feeding them a diet devoid of vitamin K and by rigorously preventing coprophagy. After one week, circulating prothrombin concentrations were between 5 and 10% of initial values, and various amounts of phylloquinone, menaquinone-4, and menaquinone-9 were given in a single dose either subcutaneously, orally, or colorectally. The relative 'vitamin K activities' of these compounds were assessed by comparing their ability to support prothrombin synthesis after subcutaneous injection. Intestinal and colonic absorption were deduced from the difference between subcutaneous and either oral or colorectal administration of the vitamers. It is concluded that the colonic absorption of all three forms of vitamin K is extremely poor, suggesting that physiological menaquinones in the colon do not contribute substantially to vitamin K status in rats. Furthermore, the stimulation of prothrombin synthesis by menaquinone-9 lasted much longer than that by the two other K-vitamers, resulting in a substantially higher 'vitamin K activity' of menaquinone-9.

Isolation and identification of menaquinone-9 from purified nitrate reductase of Escherichia coli.
On the basis of the observation that nitrate reductase from Escherichia coli is sensitive to UV irradiation with an action spectrum indicative of a naphthoquinone (F. Brito and M. Dubourdieu, Biochem. Int. 15:1079-1088, 1987), we extracted and characterized quinone components from two different preparations of purified nitrate reductase. A soluble form of nitrate reductase, composed of alpha and beta subunits, was purified after release from the membrane fraction by heat treatment, and a detergent-solubilized form, containing alpha, beta, and gamma (cytochrome bNR) subunits, was purified in the presence of Triton X-100. Extraction of soluble alpha beta form with chloroform-methanol yielded several UV-absorbing components, which were characterized as menaquinone-9 with an oxidized side chain and further photodestruction products of the menaquinone. The total amount of menaquinone extracted into the organic phase was estimated to be 0.97 mol/mol of alpha beta dimer. Extraction of the detergent-solubilized alpha beta gamma form by a similar procedure yielded two naphthoquinone-like components which were characterized by mass spectrometry as the oxidized forms of menaquinone-9 and demethylmenaquinone-9. In this case, the molar ratio of total naphthoquinone to the alpha beta dimer was estimated to be greater than 6:1. When cytochrome bNR and detergent were eliminated from the detergent-solubilized enzyme by heat treatment and ion-exchange chromatography, only menaquinone-9 could be identified in the organic extract of the active alpha beta product. These results suggest that menaquinone-9 is specifically bound to the alpha beta dimer and may be the UV-sensitive component in the pathway of electron transfer catalyzed by nitrate reductase.

Comparative distribution, metabolism, and utilization of phylloquinone and menaquinone-9 in rat liver.
The liver of most species contains a spectrum of bacterially produced menaquinone homologs as well as the major dietary form of vitamin K, phylloquinone. The relative utilization of phylloquinone and menaquinone-9 (MK-9) as substrates for the microsomal vitamin K-dependent gamma-glutamyl carboxylase was determined in a rat model. Vitamin K 2,3-epoxide, the co-product of the carboxylation reaction, is recycled to the quinone form of the vitamin by a microsomal vitamin K epoxide reductase. This enzyme activity was blocked by warfarin administration, and the appearance of the hepatic epoxides of phylloquinone and MK-9 was determined as a measure of their utilization by the carboxylase. When the liver contained equimolar amounts of phylloquinone and MK-9, four times as much phylloquinone epoxide as MK-9 epoxide was present in the liver 1 hr after warfarin administration. These data suggest that hepatic MK-9 is not as efficiently utilized as phylloquinone. The data obtained have also demonstrated a previously unrecognized difference in phylloquinone and menaquinone metabolism. MK-9 epoxide, and to a lesser extent MK-9, was preferentially localized in the mitochondria, while higher concentrations of phylloquinone were found in the microsomes.

Colonic absorption of menaquinone-4 and menaquinone-9 in rats.
The colonic absorption of menaquinones was examined in rats by the in situ loop method. The overall disappearance of [14C]menaquinone-4 from the colonal loop was approximately 6% at 3 h and much slower than that of menadione. After administration of [14C]menaquinone-4 into the jejunal loop with bile, approximately 17% of unchanged menaquinone-4 was recovered in the lymph after 6 h, but none was found when the administration had been into the colonal loop. Portal absorption of menaquinone-4 from the colon was detected and the unchanged form (approximately 23% of the absorbed radioactivity) was identified in the mesenteric venous blood. When menaquinone-9 was administered into the colon, almost all was recovered from the colonal loop. No transfer of menaquinone-9 from the colon into the lymph or blood was observed at 6 h after dosing. The present observations indicate that only a part of bacterially produced menaquinones is absorbed from the colon via the portal pathway, but the absorption rates of menaquinones decrease markedly with an increase in the number of isoprenoid units.

Comparative metabolism of phylloquinone and menaquinone-9 in rat liver.
The hepatic turnover of phylloquinone and menaquinone-9 (MK-9) and their relative efficacy in satisfying the dietary requirement for vitamin K were compared in male rats. Rats fed 1.1 mumol phylloquinone/kg diet had higher initial liver and serum vitamin K concentrations than rats fed an equimolar amount of MK-9. The initial rate of hepatic turnover of phylloquinone was two to three times as rapid as that of MK-9. After about 48 h of vitamin K restriction there were no significant differences in hepatic vitamin K concentration of rats fed phylloquinone or MK-9. Phylloquinone was much more effective than MK-9 in maintaining normal vitamin K status at low dietary concentrations (0.2 mumol/kg diet), whereas at high dietary concentrations (5.6 mumol/kg diet) they were equally effective.
