Features of the composition of microbial communities of low-temperature mineral springs Khongor-Uula (Tunka valley, Republic of Buryatia)

This article presents the results of hydrochemical and microbiological studies of water, sedimentations and microbial mats of Khongor-Uula mineral springs. The waters of the springs belongs to cold ferrous sulfate-carbonate, sodium-calcium-magnesium type of waters. It characterized by low salinity and slightly alkaline pH values. In native samples enzymatic proteolytic activity was detected.It indicate the destruction of labile organic matter by microbial communities. The high values of extracellular peptidase activity in the “gastric” spring weremeasured. The diversity of dominant genotypes was determined using molecular methods in microbial communities of samples from the Khongor-Uula. In the microbial community, the representatives of various phylogenetic lines were found, the representatives of Proteobacteriadominate.
