Removal of microcystin-LR from aqueous solutions using % burn-off activated carbon of waste wood material [PDF]
, 2014 The activated carbon (AC), prepared at different burn-off rates, showed a high uptake of methylene blue. At 93% burn-off, methylene blue uptake was 620 mg/g.

Oxidative stress biomarkers in Clarias gariepinus (Burchel, 1822) exposed to Microcystin-LR
Beni-Suef University Journal of Basic and Applied Sciences, 2017 Stress levels inflicted by microcystin-LR extracted from Microcystis aeruginosa were assessed by estimating the effects on the oxidative stress biomarkers in the liver, muscle and gill tissues of Clarias gariepinus. Microcystin-LR was administered to the

Further characterization of glycine-containing microcystins from the McMurdo Dry Valleys of Antarctica [PDF]
, 2015 Microcystins are hepatotoxic cyclic peptides produced by several cyanobacterial genera worldwide. In 2008, our research group identified eight new glycine-containing microcystin congeners in two hydro-terrestrial mat samples from the McMurdo Dry Valleys ...

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

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.

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 ...

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,

UM BREVE ESTUDO SOBRE A INATIVAÇÃO DA TOXINA MICROCISTINA-LR POR IRRADIAÇÃO GAMA E ANÁLISE POR METODOLOGIAS HPLC-SPE ONLINE E ESPECTROMETRIA DE MASSAS [PDF]
Química NovaMany of the toxins produced by cyanobacteria have multiple variants, some being more toxic than others. Microcystins are a group of toxins produced by cyanobacteria that have approximately 100 variants with LD50 (lethal dose 50%) values ranging from 25 ...

Exploring the direct effects of microcystin-LR on DNA via using cross-technical means
Ecotoxicology and Environmental Safety, 2022 Microcystin-leucine arginine (MC-LR) is the most toxic and abundant microcystin produced by cyanobacteria. Previous studies have demonstrated that MC-LR can lead to DNA damage by increasing intracellular reactive oxygen species content to induce ...
