When water is pumped into oil-bearing seams to increase oil production, the microorganisms in the injected water fall into favorable ecological conditions and, quickly adapting, form a biocenosis and begin to actively develop. Among the anaerobic microorganisms, the most hazardous from the corrosion viewpoint are the sulfate-reducing bacteria (SRB), which are the main producers of hydrogen sulfide as the product of anaerobic respiration. This paper reports on the effect of gamma rays on the metabolic study of SRB Desulfovibrio desulfuricans in the nutrient medium Postgate B. The radioactive source used is a /sup 60/CoK-125 unit with a power of 700 rad/sec. The required dose of gamma rays was calculated from the exposure times of samples with the test medium in the radiation zone o the isotope /sup 60/Co. The criterion characterizing the effectiveness of suppression of development of the bacteria is the concentration of biogenic hydrogen sulfide produced, as determined by iodometric titration.
