Abstract
Results of studies of biodiversity of bacteria of Enterobacteriaceae family and of non-enzymatic group belonging to the group of potentially pathogenic bacteria are presented. They are found for the first time, mainly in litoral regions of the lake, and have not been found in the pelagial zone. Bacteria of 31 species from 14 genera have been identified. The results of isolation and identification have demonstrated that the most frequent in litoral zones were bacteria from genera Acinetobacter, Pseudomonas, Citrobacter and Enterobacter. The most frequently occurring were the following species: Acinetobacter calcoaceticum var. Joffi (7.7 %), Pseudomonas aeruginosa (6.3 %), Alcvaligenes spp. (3.5 %), and Escherichia coli (3.2 % of all the heterotrophic microorganisms found).
