THE FIRST INVESTIGATONS OF CYANOTOXINS PRESENCE IN WATERBODIES AND WATERCOURCES OF BELARUS

The estimation of species composition, abundance and biomass cyanobacteria in “bloom” as well the search for toxic has been undertaken first time 20 water bodies courses Belarus mainly used public recreation. There were identified 50 representatives assigned to 18 genera, among them three marked Belarus: Snowella atomus Komárek et Hindák., Anabaenopsis arnoldii Aptekar, kelifii Kog. By combining molecular-biological analytical methods by using genetic markers when studying «water blooms» genes responsible synthesis hepatotoxic microcystin, nodularin, cylindrospermosin neurotoxic saxitoxin was undertaken. It shown that all investigated lakes rivers there cyanobacterium relating Anabaena Microcystis genera can synthesize highly microcystins – LR, RR, YR. Saxitoxin close it variants paralytic toxins such goniatoksins 5, 6, dekarbamoilgoniatoksin 2, dekarbamoilsaksitoksin neosaksitoksin found 7 waterbodies.
