Microbial diversity in alkaline salt lakes of Priononya (Transbaikal region)

The results of physico-chemical and microbiological researches of Priononye’s mineral lakes present in article. The lakes water is characterized by pH value to 10,1 and mineralization value to 470 g/l. The environment and quantity of organic matter bacteria- destructors in the water and bottom sediments were studied. It is established that the dominant phylums in the microbial community of the studied lakes are Proteobacteria (30-52%), Firmicutes (5-20%), Bacteroidetes (11-24%), with differences at the level of classes and genera. In the microbial community of the highly mineralized Lake Borzinskое, a significant proportion of Аrchebacteria of the Euryarchaeota class (33%) was detected.
