摘要：Objective: In order to study low activity of petroleum-degrading strains. Methods: We added oil degrading strains to compost, the compost is made of soybean meal, corn flour, bran and sawdust, in the last, we added the oil degrading strains-compost contaminated soil. Result: The oil removal rates were determinated by gravimetric method. The oil removal rates of control group, oil contaminated soil compost group and oil contaminated soil oil degrading strains-compost group were 23.4%, 31.6% and 49.7% on 60th day, respectively. Compared with the control group, the oil removal rate of oil contaminated soil oil degrading strains-compost group increased by 26.3%. Conclusion: The research indicates that oil contaminated soil oil degrading strains-compost can improve petroleum-degrading rates.
