Halophilic bacteria - primary destructors in the salt lake Gudzhirganskoe (Barguzin valley, North Cisbaikalia)

The study of the microbial community in bottom sediments of Lake Gudzhirganskoe is presented in this article. Quantitative data on the calculation of heterotrophic bacteria showed the widely distribution of halophilic prokaryotes capable of carrying out the primary destruction of organic matter in extreme conditions of salinity. The sequence of total DNA have shown that chemoorganotropic bacteria responsible for the destruction of organic matter dominated in the microbial community of bottom sediment. These bacteria are typical representatives of saline environment and are well adapted to physicochemical conditions of continental saline lakes.
