Cyanobacterial blooms in eutrophic water bodies are a worldwide problem. Combined effects of mixtures secondary metabolites produced by different cyanobacterial species on aquatic fauna still not well recognised. We compared the survivorship Brachionus calyciflorus Pallas (Rotifera) and Daphnia pulex Leyding (Cladocera) exposed to pure microcystin LR (MC-LR), anatoxin-a (ANTX) five extracts obtained from bloom-forming cyanobacteria Microcystis, Planktothrix Dolichospermum. The results revealed response organisms high concentrations MC-LR, ANTX complex extracts. extracts' toxicity invertebrates was higher than that exerted cyanotoxins dependent composition metabolites: Microcystis spp. extract containing anabaenopeptins A B, aeruginosamide, four variants cyanopeptolins MCs toxic either organisms, whereas agardhii (I), A, F, 915, oscillamide Y, aeruginosins MC more daphnids rotifers. another P. agarhdii (II) biomass two samples Dolichospermum also affected rotifer cladoceran, however, various extent. It strongly suggests non-ribosomal oligopeptides, other MCs, had essential contribution observed their particular or populations can vary depending metabolite profiles cyanobacteria.
