Toxicity of Microcystis species isolated from natural blooms and purification of the toxin.
Microcystis strains (2 toxic and 18 nontoxic to mice) were isolated from toxic waterblooms that had been collected from Lake Kasumigaura, Ibaraki Prefecture, Japan, in August 1985. Thirteen of the strains (2 toxic and 11 nontoxic) were Microcystis aeruginosa, 2 (nontoxic) were Microcystis wesenbergii, and the other 5 were difficult to identify. Six (1 toxic and 4 nontoxic M. aeruginosa and 1 M....
متن کاملSpecies-dependent variation in sensitivity of Microcystis species to copper sulfate: implication in algal toxicity of copper and controls of blooms
Copper sulfate is a frequently used reagent for Microcystis blooms control but almost all the previous works have used Microcystis aeruginosa as the target organism to determine dosages. The aim of this study was to evaluate interspecific differences in the responses of various Microcystis species to varying Cu2+ concentrations (0, 0.05, 0.10, 0.25, and 0.50 mg L-1). The half maximal effective ...
متن کاملTo increase size or decrease density? Different Microcystis species has different choice to form blooms
The buoyancy of Microcystis colonies is a principal factor determining blooms occurrence but the knowledge of seasonal variation in buoyancy is quite poor because of challenge in analysis method. In this study, a method based on the Stokes' Law after researching on the effects of shapes on settling velocity of Microcystis colonies, whose gas vesicles were collapsed, to accurately measure densit...
متن کاملSelective control of toxic Microcystis water blooms using lysine and malonic acid: an enclosure experiment.
Three enclosures (10 x 10 x 1.5-1.3 m in depth) were set beside Dianch Lake, Kunming, People's Republic of China, for the period from July 28 to August 26, 2002. The enclosures were filled with cyanobacterial (Microcystis aeruginosa) water bloom-containing lake water. Lake sediment that contained macrophytes and water chestnut seeds was spread over the entire bottom of each enclosure. Initially...
متن کاملcyanobacterial blooms and their toxicity in vojvodina lakes, serbia
the presence of cyanobacteria (blue-green algae) is a significant indicator of water quality,having in mind that several genera have the quality of producing cyanotoxins, which are harmful to animals,plants and humans. seven lakes in vojvodina (republic of serbia) were examined in may and september 2007 for cyanobacterial presence and cyanotoxins content, chl a concentration and index of phosph...
