Microcystins are ubiquitous toxins produced by photoautotrophic cyanobacteria. Human exposures to microcystins occur through the consumption of contaminated drinking water, fish and shellfish, vegetables, and algal dietary supplements and through ...

Effects of different doses of microcystin-LR exposure on gut development and the microbiota of Xenopus laevis tadpoles [PDF]
Background Although the acute toxicity of microcystin-LR has been widely confirmed, its effects on aquatic organisms at environmental concentrations have not been systematically studied.

The Cyanobacterial Hepatotoxin Microcystin Binds to Proteins and Increases the Fitness of Microcystis under Oxidative Stress Conditions [PDF]
Microcystins are cyanobacterial toxins that represent a serious threat to drinking water and recreational lakes worldwide. Here, we show that microcystin fulfils an important function within cells of its natural producer Microcystis.

Potential Linkage Between Zebra Mussel Establishment, Cyanobacterial Community Composition, and Microcystin Levels in United States Lakes [PDF]
Zebra mussel invasion of North American lakes during the last century may play an important role in the occurrence of toxic cyanobacterial blooms. However, empirical evidence quantifying their influence on cyanobacterial community dynamics at broad ...

Persistence of Microcystin in Three Agricultural Ponds in Georgia, USA [PDF]
Cyanobacteria and their toxins can have multiple effects on agricultural productivity and water bodies. Cyanotoxins can be transported to nearby crops and fields during irrigation and may pose a risk to animal health through water sources.

The use of a benign fast-growing cyanobacterial species to control microcystin synthesis from Microcystis aeruginosa [PDF]
IntroductionMicrocystis aeruginosa (M. aeruginosa), one of the most abundant blue-green algae in aquatic environments, produces microcystin by causing harmful algal blooms (HABs).

Microbial degradation is an important route for removing environmental microcystins (MCs). Here, we investigated the ecological distribution of microcystin degraders (mlr-genotype), and the relationship between the substrate specificity of the ...

Impact of temperature on the temporal dynamics of microcystin in Microcystis aeruginosa PCC7806
Cyanobacterial blooms pose a serious threat to water quality and human health due to the production of the potent hepatotoxin microcystin. In microcystin-producing strains of the widespread genus Microcystis, the toxin is largely constitutively produced,

Microcystin as a biogeochemical cycle: Pools, fluxes, and fates of the cyanotoxin in inland waters
Microcystin poses a serious threat to aquatic ecosystems and human health. There is a pressing need to understand the production, movement, and storage of microcystin in lakes.

Variability in microcystin quotas during a Microcystis bloom in a eutrophic lake.
Microcystis is a bloom-forming genus of cyanobacteria with some genotypes that produce highly toxic microcystin hepatotoxins. In waterbodies where biological and physical factors are relatively homogenous, toxin quotas (the average amount of toxin per ...
