Detection of Variants of Microcystin Produced by Microcystis Aeruginosa in Some Burrow Pits of Kano, Nigeria
Water samples of some burrow pits in Kano metropolis were examined for Microcystis aeruginosa and their ability to produce toxins. Identification for the organisms was achieved by the use of standard procedure and its pure culture was obtained by capillary pipette technique. The pure culture was harvested and dried at 25oC. These were kept in refrigerator before being subjected for the analysis...
متن کاملMicrocystin production by Microcystis aeruginosa in a phosphorus-limited chemostat.
The production of microcystins (MC) from Microcystis aeruginosa UTEX 2388 was investigated in a P-limited continuous culture. MC (MC-LR, MC-RR, and MC-YR) from lyophilized M. aeruginosa were extracted with 5% acetic acid, purified by a Sep-Pak C(18) cartridge, and then analyzed by high-performance liquid chromatography with a UV detector and Nucleosil C(18) reverse-phase column. The specific gr...
متن کاملInfluence of temperature, mixing, and addition of microcystin‐LR on microcystin gene expression in Microcystis aeruginosa
Cyanobacteria, such as the toxin producer Microcystis aeruginosa, are predicted to be favored by global warming both directly, through elevated water temperatures, and indirectly, through factors such as prolonged stratification of waterbodies. M. aeruginosa is able to produce the hepatotoxin microcystin, which causes great concern in freshwater management worldwide. However, little is known ab...
متن کاملγ-Lindane Increases Microcystin Synthesis in Microcystis aeruginosa PCC7806
HCH factories, and the waste dumpsites associated to its production, have become a global environmental concern, and their runoff could pollute ground and surface waters with high levels of the pollutant. In this study, the influence of lindane (γ-HCH) on microcystin production has been investigated in Microcystis aeruginosa PCC7806. This toxic cyanobacterium is highly tolerant to γ-lindane (20...
متن کاملDaphnia growth on microcystin-producing and microcystin-free Microcystis aeruginosa in different mixtures with the green alga Scenedesmus obliquus
The hypothesis that negative effects of Microcystis on Daphnia growth and reproduction can be explained from the presence of microcystin in the Microcystis cells was tested by comparing the effects on Daphnia life history characteristics of a microcystin-free mutant strain and microcystin-containing strain of the cyanobacterium Microcystis aeruginosa PCC7806. To avoid nutritional deficiency, Mi...
