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.

strain A134 was isolated from colonies collected from Lake Kinneret (Sea of Galilee), Israel. The culture media inhibited the growth of (strain MGK). The crude extract of a large-scale culture of A134 was separated in a few chromatographic steps to yield three new secondary metabolites, 9-chlorolumichrome (), veronimide () and veronipyrazine (), along with a known lumichrome and several known diketopiperazines.

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.

Microcystis sp. are major players in the global intensification of toxic cyanobacterial blooms endangering the water quality of freshwater bodies. A novel green alga identified as Scenedesmus sp.
