Dolichospermum and Aphanizomenon as neurotoxins producers in some Russian freshwaters.

摘要: Last decades, cyanobacterial blooms have been commonly reported in Russia. Among the boom-forming species, potential toxin producers identified. The aim of this paper was to study presence neurotoxic compounds - saxitoxins and anatoxin-a water bodies from different regions We also made attempts identify neurotoxin-producing genera. good convergence results obtained by light microscopy, PCR LC-MS/MS analyses indicated active neurotoxin producing species all investigated bodies. Saxitoxin detected phytoplankton 4 Central European Russia West Siberia, including lake reservoirs used as a source for potable water. differed with respect saxitoxin which belonged Aphanizomenon and/or Dolichospermum For first time, we quantitative data on intracellular concentration Russian freshwaters using LC-MS/MS. Anatoxin-a only lakes Northwestern In eutrophic shallow Lower Suzdal Lake, stated anatoxin-a-producing genus. large artificial hypertrophic Sestroretskij Razliv it very likely that both dominant flos-aquae planctonicum were producers.
