Eutrophication and Warming Boost Cyanobacterial Biomass and Microcystins

Eutrophication and Warming Boost Cyanobacterial Biomass and Microcystins

Eutrophication and warming are key drivers of cyanobacterial blooms, but their combined effects on microcystin (MC) concentrations are less studied. We tested the hypothesis that warming promotes cyanobacterial abundance in a natural plankton community and that eutrophication enhances cyanobacterial biomass and MC concentrations. We incubated natural seston from a eutrophic pond under normal, h...

Effects of microcystins, cyanobacterial toxins, on Mammalian cells and organs.

Microcystins are hepatotoxic cyclic heptapeptides characterized by the presence of non proteinogenic b-amino acid ADDA. They are produced by numerous bloom forming cyanobacterial genera. Acute lethal intoxications of humans are rare, but especially chronic exposure to these toxins presents a serious threat to the health of human population. Microcystins enter cells mostly via bile acid transpor...

Protein measurements of microalgal and cyanobacterial biomass.

The protein content of dry biomass of the microalgae Porphyridium cruentum, Scenedesmus almeriensis, and Muriellopsis sp. and of the cyanobacteria Synechocystis aquatilis and Arthrospira platensis was measured by the Lowry method following disruption of the cells by milling with inert ceramic particles. The measurements were compared with the Kjeldahl method and by elemental analysis. The nitro...
