Description
Summary:Data on the distribution and abundance of bacteria of the genus Bacillus in the bottom sediments of Lake Khubsugul have shown the predominance of strains that preferred low temperatures. This indicates fairly cold temperature conditions on the territory of the Khubsugul drainage area. On the whole, the dynamics of interchange of minimums and maximums of abundance of bacteria of the genus Bacillus is similar to the global climate fluctuations. Study of the enzymatic activity of pure cultures revealed that most strains studied possessed proteolytic activity; consequently, the dynamics of bacteria development is correlated with the supply of organic nitrogen-containing compositions.
