The response of Microcystis aeruginosa strain MGK to a single or two consecutive H O applications.

Various approaches have been proposed to control/eliminate toxic Microcystis sp. blooms including H O treatments. Earlier studies showed that pre-exposure of various algae to oxidative stress induced massive cell death when cultures were exposed to an additional H O treatment.

Casting a net: fibres produced by Microcystis sp. in field and laboratory populations.

The reasons for the apparent dominance of the toxic cyanobacterium Microcystis sp., reflected by its massive blooms in many fresh water bodies, are poorly understood. We show that in addition to a large array of secondary metabolites, some of which are toxic to eukaryotes, Microcystis sp.
