Photochemical Reactions of Microcystin-LR Following Irradiation with UV Light
Photochemical reactions of microcystin-LR, a toxic compound produced by some blue green algae, were investigated. Ultraviolet absorption of microcystin-LR was assessed. Time-dependent density functional theory (TDDFT) calculations indicated that absorption peak at 238 nm was mainly due to excitation of electrons from the linear chain structure Adda of microcystin-LR. Irradiation of microcystin-...
متن کاملInteraction of microcystin-LR with SuperChar: water decontamination and therapy.
Activated charcoal (SuperChar) has been recommended for therapeutic use against poisoning by several toxic agents, but it has not been tested against microcystin-LR toxicosis. Microcystin-LR, a cyclic heptapeptide isolated from fresh water blue-green algae, has been shown to be a potent hepatotoxin in animals and in man. Studies were performed to determine the degree of in vitro adsorption of m...
متن کاملA Novel Photocatalytic Material for Removing Microcystin-LR under Visible Light Irradiation: Degradation Characteristics and Mechanisms
BACKGROUND AND PURPOSE Microcystin-LR (MC-LR), a common toxic species in contaminated aquatic systems, persists for long periods because of its cyclic structure. Ag3PO4 is an environment-friendly photocatalyst with relatively good degradation capacity for hazardous organic pollutants. This study aimed to investigate the degradation capacity of Ag3PO4 for MC-LR under visible light. METHODS An ...
متن کاملInfluence of temperature, mixing, and addition of microcystin‐LR on microcystin gene expression in Microcystis aeruginosa
Cyanobacteria, such as the toxin producer Microcystis aeruginosa, are predicted to be favored by global warming both directly, through elevated water temperatures, and indirectly, through factors such as prolonged stratification of waterbodies. M. aeruginosa is able to produce the hepatotoxin microcystin, which causes great concern in freshwater management worldwide. However, little is known ab...
