[Generation and release of Microcystin-lR by Microcystis aeruginosa under hydroquinone inhibition]. Huan jing ke xue= Huanjing kexue, 2014, Volume: 35, Issue:6 The generation and release of algal toxin Microcystin-LR (MCLR), as well as the intracellular organic chemicals were studied during the inhibition processes of Microcystis aeruginosa using hydroquinone as the inhibitor. According to the dose-effect relationship, the corresponding dosages of EC20, EC50, EC70, EC90, EC99 were added to the algae suspension. The TOC was determined by the total organic carbon analyzer, and the three-dimensional fluorescence spectrum was obtained by the fluorescence spectrophotometer. The results showed that the generation of MCLR was inhibited at EC20 and the total MCLR was 72.4%-83.0% of the control samples. Whereas the cells were stimulated to produce higher amount of MCLR, and the total MCLR was 1.77-3.13 times as high as that of the control samples at EC50-EC99. The intracellular MCLR was largely released to the water at EC70-EC99. The release of other intracellular organic chemicals mainly referred to humic-like and fulvic-like substances, which were unstable and had an obvious degradation and transformation after 6 days of cultivation.

The alteration of Microcystis aeruginosa biomass and dissolved microcystin-LR concentration following exposure to plant-producing phenols. Environmental toxicology, 2007, Volume: 22, Issue:4 Plant-producing phenols could strongly inhibit the growth of toxic cyanobacteria genera, but the ecological consequences of this action are still unknown. In this work, the activity of selected phenols in relation to the strain Microcystis aeruginosa was investigated. We have found that the mechanism of the growth inhibition could involve both the inhibition of the photosynthetic system and the alkaline phosphatase activity. The excretion of a high amount of microcystin-LR to the environment was observed as a final result of the application of phenols to the cyanobacterial culture. This finding suggests that first of all an algicidal effect of phenols was probably the reason of the cyanobacterial biomass decreasing.
