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

Journal of Applied Polymer Science, Volume 142, Issue 44, November 20, 2025.
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.

A fluorescent-labeled microcystin-LR terbium cryptate

Journal of the Brazilian Chemical Society, 2006
A new fluorescent labeled compound of microcystin-LR with terbium cryptate was obtained by initial conjugation of microcystins-LR with aminoethanethiol followed by the reaction with the ester group of terbium cryptate.

Hepatocyte apoptosis is triggered by hepatic inflammation in common carp acutely exposed to microcystin-LR or chronically exposed to Microcystis

Ecotoxicology and Environmental Safety
Cyanobacterial blooms pose a serious threat to the survival of fish because of the hepatotoxicity of microcystins produced by toxic cyanobacteria such as Microcystis.

Photocatalytic degradation of eleven microcystin analogues and nodularin by TiO2 coated glass microspheres [PDF]

, 2015
Microcystins and nodularin are toxic cyanobacterial secondary metabolites produced by cyanobacteria that pose a threat to human health in drinking water. Conventional water treatment methods often fail to remove these toxins. Advanced oxidation processes

New Report of Cyanobacteria and Cyanotoxins in El Pañe Reservoir: A Threat for Water Quality in High-Andean Sources from PERU

Toxins
Cyanobacteria are cosmopolitan organisms; nonetheless, climate change and eutrophication are increasing the occurrence of cyanobacteria blooms (cyanoblooms), thereby raising the risk of cyanotoxins in water sources used for drinking, agriculture, and ...
