Abstract

In this article, the types of microorganisms found in the hydrostructure of Lake Son-Kul, their quantitative ratio, and their significance in the ecosystem are investigated. For this, water samples were collected from different parts of the lake and analyzed under laboratory conditions. The study provides extensive information about the biodiversity of bacteria in the aquatic environment of Lake Son-Kul and their main biological functions in the ecosystem. Water samples were collected in July from the shoreline of Lake Son-Kul at horizontal distances of 5 and 15 m, as well as from vertical depths: upper (20-50 cm), middle (1-2 m), and bottom (5-8 m) layers. These samples included representatives of microorganisms belonging to the phyla Proteobacteria, Bacteroidetes, Actinobacteria, Cyanobacteria, and Firmicutes. Cyanobacteria predominated in the upper layer of water, Actinobacteria in the middle layer, and Proteobacteria in the bottom layer. The study found that the E. coli bacteria were not present in water samples from different depths, however, bacteria belonging to the genera Enterobacter, Pseudomonas, and Mycobacterium were detected. According to quantitative indicators, Enterococcus bacteria predominated, and the level of fecal contamination was considered low or absent
