Key Words Isolation identification and physiological characteristics of some sulfur-reducing microbes
Abstract This work was designed to illustrate physiological effects on the elimination of sulfur and its compounds in petroleum using sulfur-reducing bacteria. Deulfurizing bacteria were collected from sewage and soil at several areas in Soul and Ulsan, Korea. Seven species of sulfur-reducing microbes isolated were identified as: Pseudomonas marginata, Ps.effusa, Ps. putrefaciens, Ps.pseudcmcnelli, Ps. xanthochlora, Ps.bowlesiae, and Ps.aeruginosa. And some experiments were performed to define the growing characteristics of the Pseudomonads and the results obtained are as follows: 1) Shaking culture method was more effective for the growth of the cells than stagnant culture. 2) Beef peptone medium was better for the growth than other media. 3) Cuprous chloride of 50 ppm and cupper sulfate of 300 ppm treated, respectively, in the medium were effective for the growth. 4) Benzene of toluene of 5,000 ppm and petroleum ether of 50,000 ppm did not show remarkable inhibitory effects on the growth.
