Widespread distribution and identification of eight novel microcystins in Antarctic cyanobacterial mats [PDF]
, 2008 The microcystin content and cyanobacterial community structure of Antarctic microbial mat samples collected from 40 ponds, lakes and hydro-terrestrial environments were investigated. Samples were collected from Bratina Island and four of the Dry Valleys;

A Review of Common Cyanotoxins and Their Effects on Fish
Toxics, 2023 Global warming and human-induced eutrophication drive the occurrence of various cyanotoxins in aquatic environments. These metabolites reveal diversified mechanisms of action, encompassing cyto-, neuro-, hepato-, nephro-, and neurotoxicity, and pose a ...

Structural Diversity, Characterization and Toxicology of Microcystins
Toxins, 2019 Hepatotoxic microcystins (MCs) are the most widespread class of cyanotoxins and the one that has most often been implicated in cyanobacterial toxicosis.

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.

Increasing Microcystis cell density enhances microcystin synthesis: a mesocosm study [PDF]
, 2012 An experimental protocol using mesocosms was established to study the effect of Microcystis sp. cell abundance on microcystin production. The mesocosms (55 L) were set up in a shallow eutrophic lake and received either no (control), low (to simulate a ...

Microcystins-Loaded Aged Nanoplastics Provoke a Metabolic Shift in Human Liver Cells
, 2023 Studies concerning the toxicity of pollutant-loaded nanoplastics (NPs) toward humans are still in their infancy. Here, we evaluated the adsorption of microcystins (MCs) by pristine and aged polystyrene nanoplastics (PSNPs), prepared MCs-loaded aged PSNPS

MethodsX, 2019 Microcystis aeruginosa is a cosmopolitan cyanobacteria that continues to jeopardize freshwater ecosystem services by releasing the hepatotoxin microcystin, which can, in some cases, cause death to aquatic fauna and even humans.
