Can we effectively degrade microcystins? - Implications on human health

, 2011
Microcystins are cyclic heptapeptide toxins produced by a number of genera of cyanobacteria. They are ubiquitous in bodies of water worldwide and pose significant hazard to human, plant, and animal health. Microcystins are primarily hepatotoxins known to

Studies on the immunosuppressive effects and detection of naturally-occuring toxins [PDF]

, 2012
Episodes of toxin-producing phytoplankton occur worldwide, causing both animal and human fatalities. Toxicity occurs through consumption of phycotoxins, including azaspiracid, which accumulate in filter-feeding shellfish. Microcystins are hepatotoxins,

Microcystins with Modified Adda⁵-Residues from a Heterologous Microcystin Expression System

ACS Omega
Microcystins are hepatotoxic cyclic heptapeptides produced by some cyanobacterial species and usually contain the unusual β-amino acid 3S-amino-9S-methoxy-2S,6,8S-trimethyl-10-phenyl-4E,6E-decadienoic acid (Adda) at position-5. The full microcystin gene cluster from Microcystis aeruginosa PCC 7806 has been expressed in Escherichia coli.

Phytoremediation of microcystins using Myriophyllum aquaticum can prevent sublethal effects in a Neotropical freshwater catfish

Revista Brasileira de Ciências Ambientais
Microcystins are cyanotoxins that can be produced by cyanobacteria species such as Microcystis aeruginosa. Due to the presence of microcystins in water bodies and aquatic organisms, it needs to be monitored.

Variation of microcystins in a lake for water supply

, 2003
A site investigation was conducted to correlate the relationships between microcystins (MC) concentration and algal growth in Dianchi Lake in China. Laboratory experiments were undertaken to test the effects of sediment adsorption, photoirradiation and ...

Use of protein phosphatase inhibition assay to detect microcystins in Donghu Lake and a fish pond in China

, 2000
Seasonal variations in the level of total microcystins in water samples collected from Donghu Lake and a fish pond in Wuhan, China, were studied between March 1995 and February 1996 using a protein phosphatase inhibition assay involving a radioactive P ...

Spatio-temporal variation of cyanobacteria and cyanotoxins in public supply reservoirs of the semi-arid region of Brazil

Journal of Limnology, 2019
Cyanobacteria harmful algal blooms (CyanoHABs) have become increasingly frequent and intense in public supply reservoirs as a result of eutrophication and global climate change.
