【摘要】 通过对油井注入水中分离得到的脱硫弧菌 ( Dr.desulfuricans)的研究表明 ,该菌具有一定耐氧能力 ,属于兼性厌氧菌 ,在低还原电位环境更适于生长 ,能利用污油作为碳源 ,能够以 Fe3+ 为电子受体 ,但不能利用 NO3- 作为受体。在对数生长期H2 S释放速率增大 ,两天之中释放量达到总释放量的 95%。通过研究发现 ,如曝氧、除 SO2 - 4、除有机物和细菌共生拮抗等都可以达到抑致 SRB的生长。更多还原

【Abstract】 The research on sulfate reducing bacteria (SRB) strain Dr.desulfuricans screened from oil well flooding water shows that it is an anaerobe with oxygen resistance. The environment of low redox potential is more suitable to its growth. Waste oil can be taken as carbon source. Fe 3+ , but not NO 3- , can be used as electron acceptor. If the release rate of H 2S is increased in the logarithm growth period, the release amount during two days can reach 95% of the total release amount. The research shows that the growth of SRB can be suppressed by oxygen exposure, SO 2- 4 removal, organics removal and bacteria symbiotic antagonism.更多还原
