Microcystin-LR Removal from Water via Enzymatic Linearization and Ultrafiltration
Toxins, 2022 Microcystin-LR (MC-LR) is a toxin produced by cyanobacteria that can bloom in freshwater supplies. This study describes a new strategy for remediation of MC-LR that combines linearization of the toxin using microcystinase A, MlrA, enzyme with rejection ...

Decomposition of microcystin-LR by Fenton oxidation
Toxicon, 2001 A novel and promising method of microcystin-LR (mcyst-LR) degradation is reported. The decomposition of this cyanobacterial toxin using Fenton reagent has been observed with very low initial concentrations of H2O2 and Fe2+ (Fe3+) in the reaction mixture. Mcyst-LR was isolated from a laboratory culture of Microcystis aeruginosa PCC 7813.

Chitosan-cellulose Composite Materials: Preparation, Characterization and Application for Removal of Microcystin [PDF]
, 2013 We developed a simple and one-step method to prepare biocompatible composites from cellulose (CEL) and chitosan (CS). [BMIm+Cl−], an ionic liquid (IL), was used as a green solvent to dissolve and prepare the [CEL + CS] composites. Since majority (\u3e88%)

Oral Microcystin-LR Does Not Cause Hepatotoxicity in Pigs: Is the Risk of Microcystin-LR Overestimated? [PDF]
Exposure and Health, 2019 AbstractThe global increase of toxin-producing cyanobacteria poses a serious risk to humans. Many investigations have shown that the cyanotoxin microcystin-LR induces hepatotoxicity in rodents. However, many of these studies applied the toxin intraperitoneally or used high oral concentrations, leading to an unrealistically high bioavailability of the ...
