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.

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

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.

Atrazine Affects the Circadian Rhythm of Microcystis Aeruginosa
Chronobiology International, 2013This study provides original data regarding the effects of atrazine (Atr) on the circadian rhythm of the cyanobacterium Microcystis aeruginosa. The results reveal that the circadian rhythms of the central circadian oscillator genes reached their peaks from 1 to 2.5 h after the light was switched on, and the circadian rhythms of physiologically related ...

Effects of nitrate on nitrite toxicity to Microcystis aeruginosa
Marine Pollution Bulletin, 2012The aim of this study was to investigate the effect of nitrate on nitrite toxicity to Microcystis aeruginosa. Short-term uptake experiment revealed nitrate could depress the nitrite active uptake. The long-term experiment of nitrate effects on nitrite toxicity showed a negative relationship between the growth and intracellular nitrite levels of M ...

Physiological and biochemical responses of Microcystis aeruginosa to phosphine
Environmental Pollution, 2019The frequent outbreaks of cyanobacteria bloom are often accompanied by the generation and release of reduced phosphorus species (e.g., phosphine), which raises interesting questions regarding their potential algae-related effects. To clarify the physiological and biochemical responses of cyanobacteria to phosphine, Microcystis aeruginosa was treated ...

Algicidal Effect of Peridinium bipes on Microcystis aeruginosa
Current Microbiology, 1998Peridinium bipes exerted an inhibitory effect on the growth of Microcystis aeruginosa. The algicidal action of water-soluble extract from P. bipes was studied. After treatment with P. bipes extract, the absorption spectrum of M. aeruginosa culture changed markedly, particularly in the ranges of 500 approximately 650 and 420 approximately 460 nm.

Iron-stimulated toxin production in Microcystis aeruginosa
Applied and Environmental Microbiology, 1995Nitrate- and phosphate-limited conditions had no effect on toxin production by Microcystis aeruginosa. In contrast, iron-limited conditions influenced toxin production by M. aeruginosa, and iron uptake was light dependent. A model for production of toxin by M. aeruginosa is proposed.

The characteristics of H6 against Microcystis aeruginosa
Environmental Science and Pollution ResearchAlgal bloom caused by Microcystis aeruginosa has always been the focus of attention; microbial algal control has the advantages of significant effect, low investment cost, and environmental friendliness; the use of microbial technology to inhibit the bloom has a broad prospect for development.
