Microcystin 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 کاملFirst report of a microcystin-containing bloom of the cyanobacterium microcystis aeruginosa in the La Plata River, South America.
This communication is the first registration of a toxincontaining bloom of the cyanobacterium Microcystis aeruginosa Kutzing in the La Plata River, Uruguay, ̈ South America. The occurrence of the species M. aeruginosa in the La Plata River was first registered in Ž . 1981 by CARP 1989 but without any toxicological evaluation. During the summer of 1999, short-term M. aeruginosa blooms were observ...
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 کاملToxic substance from a natural bloom of Microcystis aeruginosa.
A toxic substance contained in the blue-green alga Microcystis aeruginosa was purified and partially characterized. Toxic algal cells were collected from a highly eutrophic lake in Japan, and the toxin was purified by homogenization, ultrafiltration, gel filtration, and ion-exchange chromatography. The final preparation gave a single peak on high-performance liquid chromatography. The toxicity ...
