Distribution of proteolytic bacteria in Buksykhen cold springs (Northern Baikal region)

The article considers the spatiotemporal distribution of heterotrophic bacteria, in particular, the proteolytic group of bacteria in Buksykhen cold springs (Northern Baikal Region). It was found that the waters of the five outlets of Buksykhen springs are constantly cold, fresh and midly alkaline and belong to the hydrocarbonate calcium type. A comparative analysis did not revealed seasonal changes in the distribution of heterotrophic bacteria. The number of aerobic and anaerobic proteolytic bacteria, regardless of the type of sample, was quite high and reached 106 cells/ml. For the first time we isolated pure cultures of psychrotolerant proteolytic facultative anaerobic bacteria of Janthinobacterium and Yersinia genera from the Buksykhen-thyroid and Buksykhen-gastric springs, early indications suggest that they represent new species of these taxa.
