Protective Efficacy of the Antioxidants Vitamin E and Trolox AgainstMicrocystis aeruginosaand Microcystin-LR inArtemia franciscanaNauplii

Protective efficacy of the antioxidants vitamin E and Trolox against Microcystis aeruginosa and microcystin-LR in Artemia franciscana nauplii.

This study was undertaken to evaluate the protective efficacy of the antioxidants vitamin E and Trolox (a water-soluble vitamin E derivative) against the toxicity of microcystin-LR (MC-LR), Microcystis aeruginosa aqueous extract (CE), and a reference toxin, menadione sodium bisulfite (MSB), in Artemia franciscana nauplii. This was achieved by using the well-established brine shrimp bioassay. Th...

Protective Effect of Rifampicin on Microcystin-lr Induced Physiological and Haematological Changes in Rats

The cyclic peptide toxins microcystins and nodularins are the most common and abundant cyanotoxins present in diverse water systems. They have been the cause of human and animal health hazard and even death. Microcystn-LR (MC-LR) is the most common and toxic among the micrcoystin variants. The physiological effects of MC-LR have not been adequately addressed. We report here the results of our s...

Influence 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...

First report of microcystin-LR in the cyanobacterium Gloeotrichia echinulata.

Gloeotrichia echinulata is a bloom-forming cyanobacterium that is common in eutrophic lakes, and less prevalent but increasing in oligotrophic lakes. We used an enzyme-linked immunosorbent assay analysis to test for the presence of the hepatotoxin microcystin-LR (MC-LR) in G. echinulata collected from an oligotrophic lake in central New Hampshire, USA. We found that G. echinulata contained MC-L...
