Abstract

Comprehensive investigations of the Svisloch River phytoplankton were performed in 2006-2010. Samples were taken all-the-year-round at four sites: reservoirs Drozdy and Lake Komsomolskoye, sites along Vaneyev and Aranskaya streets (within the Minsk municipal section of the river). Species diversity of planktonic cyanobacteria and their contribution to phytoplankton abundance and biomass were determined. Potentially toxic cyanobacteria were detected based on the results of molecular-phylogenetic analysis. They contained a microcystin synthesis gene (mcyE). Obtained sequences belonged to the Microcystis and Anabaena genera, which were the most common in reservoirs worldwide and the most frequent agents of blooms. Several types of microcystins and a nontoxic peptide Oscillamide Y were detected in phytoplankton samples by means of LC/MS


Key words: Svisloch River, toxic cyanobacteria, Microcystis, Anabaena, microcystin, Oscillamide Y, mcyE gene, LC/MS
