Colorimetric test for the monitoring of microcystins in cyanobacterial culture and environmental samples from southeast - Brazil BJM
Almeida,Vanessa P.S.; Cogo,Karina; Tsai,Siu M.; Moon,David H..
Microcystins are hepatotoxic heptapeptides produced by some cyanobacterial genera under determined physico-chemical conditions in the environment, which are responsible for the intoxication and death of animals and humans. The detection of microcystins in potable water or recreational water is not carried out routinely in the majority of Brazilian states. The protein phosphatase 1 (PP1) inhibition test is a simple, rapid and reproducible colorimetric method. The applicability of the PP1 inhibition test was tested using Microcystis aeruginosa (strain 1, UFRJ- toxin producer) grown under controlled light and temperature condition (12/12h light/dark using 30 muE.m².s-1 at 23ºC) in a bioreactor. The total concentrations of P (24, 6 and 4 muM) and Fe (4 and 1...
