Prokaryotic diversity of microbial communities in the sediments of the Zun-Torey saline lake (Transbaikalia territory, Russia)

Soda-salt lakes are unique aquatic ecosystems are characterized by a high concentration of salts, alkalis and high PH-level which together create favorable conditions for the development of prokaryotic organisms in the water column and bottom sediments. An ideal research site is the Torey Lakes in the south of the Transbaikalia Territory. The hydrochemical parameters of water, the taxonomic composition of the microbial community in the bottom sediments of the soda-salt lake Zun-Torey (Transbaikalia Territory, Russia) have been studied, using high-throughput sequencing of the 16S rRNA gene. The studies have shown that the largest proportion in the microbial community of the bottom sediments of the soda-salt lake Zun-Torey are representatives of the following phyla: Actinobacteriota , Bacteroidota , Firmicutes , Proteobacteria . They are haloalkaliphilic microorganisms found specific in extreme habitats.
