Leucobacter corticis sp. nov., isolated from symptomatic bark of Populus × euramericana canker.
A Gram-stain-positive, aerobic, non-motile, rod-shaped bacterial strain, designated 2C-7T, was isolated from symptomatic bark of a Populus × euramericana canker. Growth occurred between 10 and 37 °C and between pH 6 and 10, with optimal growth at 30 °C and pH 7.0-8.0. Growth was present under 0-8 % (w/v) salinity conditions (optimum 1-2 %). Growth occurred in the presence of 10 mM chromium (Cr6+). The major fatty acids (≥10 %) of the novel strain were anteiso-C15 : 0, anteiso-C17 : 0 and iso-C16 : 0. The polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phospholipid, glycolipid and two unknown lipids. The major respiratory quinone was menaquinone MK-11. The cell wall amino acids were 2,4-diaminobutyric acid, alanine, glutamic acid and glycine. Strain 2C-7T was most similar to Leucobacter celer subsp. celer NAL101T (97.2 % 16S rRNA gene sequence similarity), 'Leucobacter kyeonggiensis' F3-P9T (97.1 %) and Leucobacter chromiireducens L-1T (97.1 %). In the phylogenetic tree, the isolate formed a single distinct branch separate from those of L. celer subsp. celer NAL101T, 'L. kyeonggiensis' F3-P9T and Leucobacter chironomi DSM 19883T. The DNA-DNA hybridization values between the novel strain and the reference strains were lower than the accepted bacterial threshold level of 70 % for species delineation. The DNA G+C content of strain 2C-7T was 70.0 mol%. Based on the data, strain 2C-7T represents a novel species in the genus Leucobacter, for which the name Leucobacter corticis sp. nov. is proposed. The type strain is 2C-7T (=CFCC 11901T=KCTC 39643T).

Agromyces insulae sp. nov., an actinobacterium isolated from a soil sample.
A novel Gram-reaction-positive, non-motile, aerobic bacterium, designated CFH S0483T, was isolated from a soil sample collected from Catba island in Halong Bay, Vietnam. 16S rRNA gene sequence analysis showed that the strain is a member of the genus Agromyces and has highest 16S rRNA gene sequence similarities with Agromyces humatus DSM 16389T (97.3 %) and Agromyces ramosus DSM 43045T (97.1 %), and similarities < 97.0 % with type strains of other species of the genus Agromyces. Strain CFH S0483T was able to grow at 10-37 °C, at pH 7.0-9.0 and tolerated NaCl up to 2.0 % (w/v). The whole-cell sugars were mannose, galactose, glucose and ribose. The isolate contained l-2,4-diaminobutyric acid, d-alanine, d-glutamic acid and glycine in the cell-wall peptidoglycan. Strain CFH S0483T exhibited a menaquinone system with MK-12, and the major fatty acids were anteiso-C15 : 0, anteiso-C17 : 0 and iso-C16 : 0. The genomic DNA G+C content of strain CFH S0483T was 71.6 mol%. Based on the phylogenetic and phenotypic analysis, and low DNA-DNA hybridization values, strain CFH S0483T could not be classified into any recognized species of the genus Agromyces. Strain CFH S0483T is therefore considered to represent a novel species of the genus Agromyces, for which the name Agromyces insulae sp. nov. is proposed. The type strain is CFH S0483T ( = KCTC 39117T = CCTCC AB 2014301T).

Leucobacter musarum subsp. musarum sp. nov., subsp. nov., Leucobacter musarum subsp. japonicus subsp. nov., and Leucobacter celer subsp. astrifaciens subsp. nov., three nematopathogenic bacteria isolated from Caenorhabditis, with an emended description of
Three Gram-stain-positive, irregular-rod-shaped, non-motile, non-spore-forming bacteria were isolated from nematodes collected from Santa Antao, Cabo Verde (CBX151T, CBX152T) and Kakegawa, Japan (CBX130T). Based on 16S rRNA gene sequence similarity, strains CBX130T, CBX151T and CBX152T were shown to belong to the genus Leucobacter. This affiliation was supported by chemotaxonomic data (2,4-diaminobutyric acid in the cell wall; major respiratory quinones MK-10 and MK-11; major polar lipids phosphatidylglycerol and diphosphatidylglycerol; major fatty acids anteiso-C15 : 0, anteiso-C17 : 0 and iso-C16 : 0). Strains CBX130T and CBX152T were found to share salient characteristics. Based on morphological, physiological, chemotaxonomic and biochemical analysis, strain CBX152T represents a novel species of the genus Leucobacter, for which the name Leucobacter musarum sp. nov. (type strain CBX152T = DSM 27160T = CIP 110721T) is proposed. Two subspecies of Leucobacter musarum sp. nov. are proposed: Leucobacter musarum sp. nov. subsp. musarum subsp. nov. (type strain CBX152T = DSM 27160T = CIP 110721T) and Leucobacter musarum sp. nov. subsp. japonicus subsp. nov. (type strain CBX130T = DSM 27158T = CIP 110719T). The third novel strain, CBX151T, showed genetic similarities with Leucobacter celer NAL101T indicating that these strains belong to the same species. Based on morphological, physiological, chemotaxonomic and biochemical differences it is proposed to split the species Leucobacter celer into two novel subspecies, Leucobacter celer subsp. celer subsp. nov. (type strain NAL101T = KACC 14220T = JCM 16465T) and Leucobacter celer subsp. astrifaciens subsp. nov.

Strain THG-MD12T, a Gram-reaction-positive, aerobic, non-motile, rod-shaped bacterium was isolated from rhizosphere soil of Ophiopogon japonicus in PR China. THG-MD12T was closely related to members of the genus Pseudoclavibacter and showed the highest 16S rRNA gene sequence similarities with Pseudoclavibacter helvolus KCTC 19531T (98.8 %) and Pseudoclavibacter chungangensis KCTC 22691T (96.9 %). DNA-DNA hybridization showed 41.9 ± 2.1 % and 12.4 ± 0.9 % DNA reassociation with P. helvolus KCTC 19531T and P. chungangensis KCTC 22691T, respectively. Chemotaxonomic analyses revealed that strain THG-MD12T possesses menaquinone-9 as the predominant respiratory quinone, 2,4-diaminobutyric acid as the diamino acid in the peptidoglycan and anteiso-C15 : 0, iso-C16 : 0, C16 : 0 and anteiso-C17 : 0 as the major fatty acids. The polar lipid profile was found to consist of diphosphatidylglycerol, phosphatidylglycerol, two unknown glycolipids and two unknown lipids. These data corroborated the affiliation of THG-MD12T to the genus Pseudoclavibacter. Thus, the isolate represents a novel species, for which the name Pseudoclavibacter terrae sp. nov. is proposed, with THG-MD12T as the type strain ( = CCTCC AB 2015124T = KCTC 39562T).

Leucobacter zeae sp. nov., isolated from the rhizosphere of maize (Zea mays L.).
A novel yellow-pigmented, aerobic, rod-shaped, non-motile bacterium, designated strain CCMF41T, was isolated from rhizosphere soil of maize (Zea mays) collected in Wufeng District, Taichung, Taiwan. Strain CC-MF41T exhibited 16S rRNA gene sequence similarity of 97.5, 97.3, 97.2 and 97.1% to Leucobacter chironomi MM2LBT (and ‘Leucobacter kyeonggiensis’F3-P9 and ‘L. humi’ Re-6, the names of which have not been validly published), Leucobactertardus K70/01T, L. komagatae IFO 15245T and ‘Leucobacter margaritiformis’ A23. However,CC-MF41T and ‘L. margaritiformis’ A23 formed a loosely bound phylogenetic lineage (with alow bootstrap value) associated with species of the genus Leucobacter. In DNA–DNA reassociation experiments, the relatedness of strain CC-MF41T to L. chironomi DSM 19883T was 57.1% (reciprocal value 29.1 %). The DNA G+C content of strain CC-MF41T was 72.1 mol% and the cell-wall peptidoglycan contained 2,4-diaminobutyric acid, alanine, glycine,glutamic acid and threonine. The major menaquinone was MK-11 and the predominant fatty acids were iso-C16 : 0, anteiso-C15 : 0 and anteiso-C17 : 0. The polar lipid profile of strain CCMF41T contained major amounts of diphosphatidylglycerol followed by an unidentified glycolipid, phosphatidylglycerol and an unknown phospholipid. Based on its phylogenetic,phenotypic and chemotaxonomic distinctiveness, strain CC-MF41T represents a novel species of Leucobacter, for which the name Leucobacter zeae sp. nov. is proposed.

Leucobacter chromiireducens subsp. solipictus subsp. nov., a pigmented bacterium isolated from the nematode Caenorhabditis elegans, and emended description of L. chromiireducens.
A yellow-pigmented, Gram-positive, aerobic, non-motile, non-spore-forming, irregular rod-shaped bacterium (strain TAN 31504(T)) was isolated from the bacteriophagous nematode Caenorhabditis elegans. Based on 16S rRNA gene sequence similarity, DNA G+C content of 69.5 mol%, 2,4-diaminobutyric acid in the cell-wall peptidoglycan, major menaquinone MK-11, abundance of anteiso- and iso-fatty acids, polar lipids diphosphatidylglycerol and phosphatidylglycerol and a number of shared biochemical characteristics, strain TAN 31504(T) was placed in the genus Leucobacter. DNA-DNA hybridization comparisons demonstrated a 91 % DNA-DNA relatedness between strain TAN 31504(T) and Leucobacter chromiireducens LMG 22506(T) indicating that these two strains belong to the same species, when the recommended threshold value of 70 % DNA-DNA relatedness for the definition of a bacterial species by the ad hoc committee on reconciliation of approaches to bacterial systematics is considered. Based on distinct differences in morphology, physiology, chemotaxonomic markers and various biochemical characteristics, it is proposed to split the species L. chromiireducens into two novel subspecies, Leucobacter chromiireducens subsp. chromiireducens subsp. nov.
