Characteristics of a Microcystin-Degrading Bacterium under Alkaline Environmental Conditions
Journal of Toxicology, 2009 The pH of the water associated with toxic blooms of cyanobacteria is typically in the alkaline range; however, previously only microcystin-degrading bacteria growing in neutral pH conditions have been isolated.

Microcystin-LR does not induce alterations to transcriptomic or metabolomic profiles of a model heterotrophic bacterium. [PDF]
PLoS ONE, 2017 Microcystins are secondary metabolites produced by several freshwater, bloom-forming cyanobacterial species. Microcystin-producing cyanobacteria co-occur with a complex community of heterotrophic bacteria.

Measurable microcystin in Ozark streams was rare during summer 2018 baseflow conditions
Agricultural & Environmental Letters, 2022 Accelerated eutrophication due to human activity has been linked to an increase in the occurrence of cyanobacteria in freshwater systems. The purpose of this study was to document the occurrence of microcystin, a common cyanotoxin, within northwest ...

Investigation of the toxicity of cyanobacterial peptides by chemical biology approaches [PDF]
, 2014 Global warming together with the extensive agriculture favours the uncontrolled growth of cyanobacteria, also called blue-green algae. Being one of the oldest life forms on our planet, they have reached evolutionary perfection over time.

UVB Radiation as a Potential Selective Factor Favoring Microcystin Producing Bloom Forming Cyanobacteria [PDF]
, 2013 Due to the stratospheric ozone depletion, several organisms will become exposed to increased biologically active UVB (280-320nm) radiation, not only at polar but also at temperate and tropical latitudes.

Non-microcystin producing Microcystis wesenbergii (Komarek) Komarek (Cyanobacteria) representing a main waterbloom-forming species in Chinese waters [PDF]
, 2008 It is well known that several morphospecies of Microcystis, such as Microcystis aeruginosa (Kutzing) Lemmermann and Microcystis viridis (A. Brown) Lemmermann can produce hepatotoxic microcystins.
