Cytotoxicity of Cyanobacterium Microcystis aeruginosa
Journal of Veterinary Medicine, Series B, 1992SummaryCytotoxic effects of crude extracts and fractions of the purification steps towards Microcystin‐LR (MCYST‐LR) were investigated in vitro. Cytoxicity was evaluated by measure of lactate dehydrogenase liberation of Chang liver cells and by hemolysis. Crude extracts of strain PCC 7806 damaged the cells within a few minutes.

Toxicological Studies on Microcystis
1981Experiments were carried out to determine whether varying toxicity of natural blooms of Microcystis is due to: a) Microcystis-bacteria interactions b) an environmental effect c) the presence of more than one strain or species of Microcystis. Partial characterization of bacteria associated with unialgal cultures, and natural blooms indicated that no ...

To elucidate the changes in the proportions of microcystin (MC)-producing Microcystis, non-MC-producing Microcystis and Anabaena strains during cyanobacteria blooms, we compared their fitness under different initial biomass ratios. Culture experiments were carried out with three cyanobacterial strains: single-celled toxic Microcystis aeruginosa PCC7806

Microcystis aeruginosa and Microcystis wesenbergii are two cyanobacteria commonly found in eutrophic shallow lakes. Previous studies reported that microcystin-producing M. aeruginosa could have an increased competitive potential on other algae and aquatic plants, and microcystin-LR (MC-LR) was regarded as an allelochemical.

Field investigations in Lake Taihu (China) were carried out from 1 June 2010 to 15 November 2010 in order to analyze environmental factors related to the succession of Microcystis wesenbergii and M. aeruginosa. M. wesenbergii dominated from the middle of July to the middle of September, and then, M. aeruginosa dominated subsequently. Cell density of M.

Photoinhibition of photosynthesis in the cyanobacterium Microcystis aeruginosa
Planta, 1983We have examined characteristics of the photoinhibition of photosynthesis which occur in the unicellular cyanobacterium Microcystis aeruginosa, following exposure to photon fluence rates in excess of those required for growth. Photoinhibition occurs following exposure of cells to a photon fluence rate of 1,000 μmol m(-2) s(-1), which is manifested as a

Zusammenfassung Die verschiedenen Vertreter der Gattung “Microcystis” im heutigen Sinn wurden in mehrere Gattungen eingereiht. Es handelt sich um folgende: Micraloa Bias. 1833 (in Kützing 1833, typus = ? Flagellaten); Microhaloa Kütz. 1833. (Irrtum, zum ersten Mal von Rabenhorst 1865 gebraucht); Microcystis Kütz.

TOXICITY OF A UNIALGAL CULTURE OF MICROCYSTIS AERUGINOSA
Canadian Journal of Microbiology, 1958A unialgal culture of Microcystis aeruginosa Kütz. emend. Elenkin, which is toxic when injected intraperitoneally into white mice, has been isolated. It produces a complex of symptoms similar to those which have been described for a number of toxic waterblooms. Two distinct factors seem to be present.
