Predicting blooms of toxic cyanobacteria in eutrophic lakes with diverse cyanobacterial communities

Abstract We investigated possibility of predicting whether blooms, if they occur, would be formed of microcystin-producing cyanobacteria. DGGE analysis of 16S-ITS and mcyA genes revealed that only Planktothrix and Microcystis possessed mcy-genes and Planktothrix was the main microcystin producer. qP...
