Dog Poisonings Associated with a Microcystis aeruginosa Bloom in the Netherlands

open access: yesToxins, 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 ...

Overexpression of Nrf2 protects against microcystin-induced hepatotoxicity in mice. [PDF]

open access: yesPLoS 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 ...

Degradation of microcystin-LR by aquatic bacteria. [PDF]

open access: yes, 2007
Microcystins are cyclic heptapeptide toxins produced by cyanobacteria. They are potentially a threat to human and domestic animals so are of worldwide interest. Microcystin-LR is stable in various environmental conditions.

Metagenomic identification of bacterioplankton taxa and pathways involved in microcystin degradation in lake erie. [PDF]

open access: yesPLoS ONE, 2013
Cyanobacterial harmful blooms (CyanoHABs) that produce microcystins are appearing in an increasing number of freshwater ecosystems worldwide, damaging quality of water for use by human and aquatic life.

Investigation of the toxicity of cyanobacterial peptides by chemical biology approaches [PDF]

open access: yes, 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.

Characteristics of a Microcystin-Degrading Bacterium under Alkaline Environmental Conditions

open access: yesJournal 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.

Episodic Decrease in Temperature Increases mcy Gene Transcription and Cellular Microcystin in Continuous Cultures of Microcystis aeruginosa PCC 7806

open access: yesFrontiers in Microbiology, 2020
Microcystins produced during harmful cyanobacterial blooms are a public health concern. Although patterns are emerging, the environmental cues that stimulate production of microcystin remain confusing, hindering our ability to predict fluctuations in ...

Microcystin-LR does not induce alterations to transcriptomic or metabolomic profiles of a model heterotrophic bacterium. [PDF]

open access: yesPLoS 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.

Laboratory-scale evaluation of algaecide effectiveness for control of microcystin-producing cyanobacteria from Lake Okeechobee, Florida (USA)

open access: yesEcotoxicology and Environmental Safety, 2021
Growth of microcystin-producing cyanobacteria in Lake Okeechobee (Florida, USA) and surrounding waters has resulted in adverse health impacts for humans and endangered species, as well as significant economic losses.
