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

Hydrogenase from the unicellular cyanobacterium, Microcystis aeruginosa
Phytochemistry, 1987Abstract A hydrogenase was isolated from a unicellular and non-nitrogen-fixing cyanobacterium, Microcystis aeruginosa strain NIES 44. The enzyme was easily solubilized and was capable of evolving hydrogen gas in the presence of reduced methyl viologen and benzyl viologen.

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 ...

Combined effects of two antibiotic contaminants on Microcystis aeruginosa
Journal of Hazardous Materials, 2014Combined toxicity of spiramycin and amoxicillin was tested in Microcystis aeruginosa. The respective 50% effective concentrations (EC50mix) expressed in toxic unit (TU) values were 1.25 and 1.83 for spiramycin and amoxicillin mixed at 1:7 and 1:1, suggesting an antagonistic interaction at the median effect level.

β-cyclocitral induced rapid cell death of Microcystis aeruginosa
Environmental Pollutionβ-cyclocitral (BCC) is an odorous compound that can be produced by bloom-forming cyanobacteria, for example, Microcystis aeruginosa. BCC has been proposed to explain the rapid decline of cyanobacterial blooms in natural water bodies due to its lytic effects on cyanobacteria cells.

Toxizität III: Experimente mit Microcystis aeruginosa KÜTZ
Botanica Marina, 1970Die Microcystis aerttginosa ist neben anderen Algen in Wasserbluten fur Mensch und Tier gefahrlich, da sie in groseren Mengen giftig sein kann. In der Literatur konnen wir bei GORHAM, in einer nicht naher angegebenen Zeitschrift von einem Symposium Meldungen uber Vergiftungen von Tieren aus vielen Teilen der Welt lesen, darunter auch eine Meldung von ...

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 ...

Purification and characterization of Microcystis aeruginosa (freshwater cyanobacterium) lectin
Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 1998Microcystis aeruginosa, strain M228, a laboratory culture of freshwater cyanobacterium, showed hemagglutinating activity against rabbit, horse and human ABO erthrocytes. Crossed absorption tests revealed the presence of a single type of lectin in the extract of M228 strain cells.
