The effect of UV irradiation on the inhibition of microorganisms is also described. The proposals of the Gubkin Institute on the joint application of biocides, biostats and UV irradiation to combat sulfate-reducing bacteria are given.</p>Sulfate-reducing bacteriabiocidesbiostatsultraviolet irradiationсульфатты қалпына келтіретін бактерияларбиоцидтербиостаттарультракүлгін сәулеленуСульфатвосстанавливающие бактериибиоцидыбиостатыультрафиолетовое облучение1.Chebotaryov YN.
