Purification and identification of microcystin-RR [PDF]

Chinese Journal of Chromatography, 2013
An effective method based on the combination of solid phase extraction and gel chromatography to extract and purify microcystin-RR (MC-RR) from natural cyanobacteria bloom was developed. Thirty five gram natural cyanobacterial bloom scum was extracted with 70% aqueous methanol. After the methanol in the crude extract was removed by a rotary evaporator,

High Levels of Structural Diversity Observed in Microcystins from Microcystis CAWBG11 and Characterization of Six New Microcystin Congeners

Marine Drugs, 2014
Microcystins (MCs) are cyclic peptides produced by cyanobacteria, which can be harmful to humans and animals when ingested. Differences in the coding of the non‑ribosomal peptide synthetase/polyketide synthase enzyme complex responsible for microcystin ...

Combined and single effects of pesticide carbaryl and toxic Microcystis aeruginosa on the life history of Daphnia pulicaria [PDF]

, 2010
The combined influence of a pesticide (carbaryl) and a cyanotoxin (microcystin LR) on the life history of Daphnia pulicaria was investigated. At the beginning of the experiments animals were pulse exposed to carbaryl for 24 h and microcystins were ...

Evidence of the cost of the production of microcystins by Microcystis aeruginosa under differing light and nitrate environmental conditions. [PDF]

PLoS ONE, 2012
The cyanobacterium Microcystis aeruginosa is known to proliferate in freshwater ecosystems and to produce microcystins. It is now well established that much of the variability of bloom toxicity is due to differences in the relative proportions of ...

A Comparative Review of the Effect of Microcystin-LR on the Proteome

Exposure and Health, 2019
Cyanobacterial toxins are a growing threat to human and animal welfare in many parts of the world. Microcystin-LR is the most widely studied of the cyanotoxins and has been implicated with hepatotoxicity, neuropathology, and genotoxicity.

Development of Chitosan/PVA Nanofibrous Membranes for Efficient Removal of Microcystis aeruginosa

Journal of Applied Polymer Science, EarlyView.
Removal of Microcystis aeruginosa from CS/PVA fibers by A‐HSBS. ABSTRACT In this study, chitosan/poly(vinyl alcohol) (CS/PVA) polymeric nanofibers were produced using the Air‐Heated Solution Blow Spinning (A‐HSBS) method and applied for the efficient removal of Microcystis aeruginosa from contaminated water.

The Biosynthesis of Rare Homo-Amino Acid Containing Variants of Microcystin by a Benthic Cyanobacterium

Marine Drugs, 2019
Microcystins are a family of chemically diverse hepatotoxins produced by distantly related cyanobacteria and are potent inhibitors of eukaryotic protein phosphatases 1 and 2A.

Cellulose‐Based Adsorbents for Decontamination of Multi‐Pollutant Contaminated Waters

Chemie Ingenieur Technik, EarlyView.
Biopolymer‐based porous adsorbents able to retain a wider spectrum of aquatic pollutants are important in the context of actual complex water pollution challenges. By blending cellulose with chitosan and by simultaneous doping it with activated carbon the spectrum of pollutants that can be adsorbed by such porous nanocomposites can be expanded ...

Effects of Dietary Astaxanthin Supplementation on Energy Budget and Bioaccumulation in Procambarus clarkii (Girard, 1852) Crayfish under Microcystin-LR Stress

Toxins, 2018
This research aimed to study the effects of astaxanthin on energy budget and bioaccumulation of microcystin-leucine-arginine (microcystin-LR) in the crayfish Procambarus clarkii (Girard, 1852).
