其他摘要：In recent years, biological desulfurization technology has attracted more and more attention from domestic and foreign researchers due to its mild reaction conditions, high efficiency, and environmental protection. In this study, bacteria were collected from oil depots, sewage treatment plants and sewage, and using a screening medium with DBT as the only sulfur source. Three strains that can degrade DBT were isolated, numbered 1, 2, and 3. Through the identification of morphological characteristics, physiological and biochemical identification and molecular identification, it is preliminarily determined that the bacteria No. 1 belongs to the genus Kinetococcus, the bacteria No. 2 is Micrococcus mutans , the bacteria No. 3 is Micrococcus luteus , and the desulfurization capacity of the three bacteria is No. 3. Bacteria > Bacteria No.1 > Bacteria No.2.
