Effects of lake warming on the seasonal risk of toxic cyanobacteria exposure
Limnology and Oceanography Letters, 2020 Incidence of elevated harmful algal blooms and concentrations of microcystin are increasing globally as a result of human‐mediated changes in land use and climate.

Chirality in microcystins [PDF]
Journal of the American Society for Mass Spectrometry, 1994 A new method has been developed to identify the isomers of amino acids by derivatization of the corresponding standards with 1-fluoro-2,4-dinitrophenyl-5-L-alanine amide (Marfey's reagent or FDAA) and analysis of the diastereomeric derivatives by a liquid chromatography-thermospray mass spectrometry technique.

Applied and Environmental Microbiology, 2020 Viral attack on cHABs may contribute to changes in community composition during blooms, as well as bloom decline, yet loss of bloom biomass does not eliminate the threat of cHAB toxicity.

Frontiers in Microbiology, 2017 Bacterioplankton plays an essential role in aquatic ecosystems, and cyanobacteria are an influential part of the microbiome in many water bodies. In freshwaters used for recreational activities or drinking water, toxic cyanobacteria cause concerns due to

Overexpression of Nrf2 protects against microcystin-induced hepatotoxicity in mice. [PDF]
PLoS ONE, 2014 Oxidative stress and glutathione (GSH) depletion are implicated in mycocystin hepatotoxicity. To investigate the role of nuclear factor erythroid 2-related factor 2 (Nrf2) in microcystin-induced liver injury, Nrf2-null, wild-type, and Keap1-hepatocyte ...

Dog Poisonings Associated with a Microcystis aeruginosa Bloom in the Netherlands
Toxins, 2013 In early autumn 2011, three dogs died after they had been exposed to a Microcystis aeruginosa bloom on Lake Amstelmeer, The Netherlands. The cyanobacterial scum from the lake contained up to 5.27 × 103 μg g−1 dry-weight microcystin, the vomit of one of ...

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.

Recent Advancement of Biosensor Technology for the Detection of Microcystin-LR
, 2020 Microcystins are a class of toxins that are mainly produced by cyanobacteria and among them, microcystin-leucine arginine (microcystin-LR) is one of the most toxic and harmful of the fresh water to...

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.
