1. The labeled atom method enables us to measure the rate of geochemical activity of microorganisms in conditions close to the natural. 2. Experiments with labeled sulfate showed that the hydrogen sulfide in underground waters of the sulfur and oil deposits of Shor -su is of biogenic origin. 3. The oxidation of hydrogen sulfide underground waters in the third and fourth horizons of Shor -Su also takes place with the participation of microorganisms. LITERATURE CITED [1] S.N.
