Název v původním jazyce

Seasonal shifts in chemotype composition of Microcystis sp. communities in the pelagial and the sediment of a shallow reservoir

Popis výsledku v původním jazyce

The various oligopeptides produced by individual Microcystis clones enable the classification of individual colonies of Microcystis in distinct peptide chemotypes. The dynamics and diversity of coexisting chemotypes are regarded as major factors influencing the microcystin-content of blooms. We compared the chemotype composition in planktonic and benthic Microcystis communities in Brno reservoir (Czech Republic) from July to November 2004 by single colony mass spectrometry. Ninetytwo peptides were selected to characterize 37 chemotypes. In the course of the season the Microcystis community became significantly less diverse in the pelagic, and in November two chemotypes both of which did not contain microcystins accounted for nearly 80% of the colonies.In contrast, other chemotypes that were dominant in the pelagic in July were no longer encountered after August, whereas some chemotypes that never accounted for high relative abundances were encountered throughout the season.
