Hydrochemical and microbiological characteristics of salt lakes Shikhalin-Nur and Khara-Nur (Southeastern Transbaikalia)

The research is aimed at studying the influence of hydrochemical parameters of salt lakes of the Torey group on its microbiological characteristics. The objects of our research are salt lakes Shikhalin-Nur and Khara-Nur, located near the Dauria station (Zabaikalsky Krai) with mineralization from 32 to 45 g/l. We have carried out a hydrochemical analysis of the main components in the lake, described the bottom sediments by layer, determined the content of organic matter in sediments of the coastal and central parts of lakes, as well as total number and biomass of bacteria, and calculated the rate of decomposition of protein and cellulose in sediments. The results of our research has shown that the coastal part of lakes is characterized by active processes of production and destruction of organic matter since it has the most favorable conditions for the functioning of microbial communities.
