Microcystis is a well-known cyanobacterial genus frequently producing hepatotoxins named microcystins. Toxin production is encoded by microcystin genes (mcy). This study aims (i) to relate the mcy occurrence in individual colonies to the presence of microcystin, (ii) to assess whether morphological characteristics (morphospecies) are related to the ...

Effects of microcystins on fish
Environmental Toxicology and Chemistry, 2006Abstract Microcystins (MCs) are hepatotoxic heptapeptides released into water during or on senescence of cyanobacterial blooms. This review details the different effects of the MCs on fish and discusses their potential consequences in aquatic food webs.

A review of neurotoxicity of microcystins
Environmental Science and Pollution Research, 2016Cyanobacterial blooms-produced microcystins are secondary metabolites which can accumulate in the food chain and contaminate water, thus posing a potential threat to the health of aquatic animals and even humans. Microcystin toxicity affects not only the liver but also the other organs, i.e., the brain.

Toxicology and Evaluation of Microcystins
Therapeutic Drug Monitoring, 2000This paper reviews the toxicity and tumor-promoting properties of microcystins. Methods for screening and/or identification of microcystins in environmental samples are discussed and compared. Specific emphasis is placed on newly developed extraction/detection methods, e.g., solid phase microextraction (SPME) technique, and capillary electrophoresis ...

Bioaccumulation of Microcystins in Lettuce
Journal of Phycology, 2012The contamination of lettuce (Lactuca sativa L.) by water‐borne crude extracts of the cyanobacterium microcystin‐producing Microcystis aeruginosa (Kützing) Kützing was investigated. The aim of the study was to determine whether bioaccumulation of microcystins occurs in lettuce foliar tissue when sprayed with solutions containing microcystins at ...

Ms identification of microcystin-LR chlorination by-products
Chemosphere, 2009 International audienceDrinking water disinfection by chlorine is known to reduce concentration of microcystin, but compounds formed are rarely considered.

Microbial Degradation of Microcystins
Chemical Research in Toxicology, 2013Hepatotoxic microcystins that are produced by freshwater cyanobacteria pose a risk to public health. These compounds may be eliminated by enzymatic degradation. Here, we review the enzymatic pathways for the degradation of these hepatotoxins, some of which are newly discovered processes.

the toxicology of microcystins
Toxicon, 1998Microcystins are a family of more than 50 structurally similar hepatotoxins produced by species of freshwater cyanobacteria, primarily Microcystis aeruginosa. They are monocyclic heptapeptides, characterised by some invariant amino acids, including one of unusual structure which is essential for expression of toxicity.

Methods for determining microcystins (peptide hepatotoxins) and microcystin-producing cyanobacteria
Water Research, 2006Episodes of cyanobacterial toxic blooms and fatalities to animals and humans due to cyanobacterial toxins (CBT) are known worldwide. The hepatotoxins and neurotoxins (cyanotoxins) produced by bloom-forming cyanobacteria have been the cause of human and animal health hazards and even death.

Microcystin-LR and chemically degraded microcystin-LR electrochemical oxidation
The Analyst, 2012Microcystins (MCs) are cyclic hepatotoxic heptapeptides produced by certain strains of freshwater cyanobacteria toxic for humans and animals. The electrochemical behaviour of microcystin-LR (MC-LR) at a glassy carbon electrode (GCE) was investigated using cyclic voltammetry (CV), square wave voltammetry (SWV) and differential pulse voltammetry (DPV ...
