%X The bioremediation effect of six different methods on oil-contaminated soil,by using of four strains isolated in oil-contaminated soil of Karamay areas,was studied under laboratory simulative conditions.All these methods were implemented by certain treatment on the contaminated soil,including:natural condition(without strain inoculums as well as ploughing),only ploughing,only bacteria strain inoculums,bacteria strain inoculums and ploughing,only immobilized microbial agents,immobilized microbial agents and ploughing,meanwhile,the biodegradation efficiency,dehydrogenase activity,microbial biomass and toxicity of the studied soil were strictly monitored during these six different treatments in pot experiments.The results showed that the removal efficiency of group F,with ploughing and immobilized microbial agents,was 78.7%.It was 49.5% higher than that of group A with neither strain inoculums nor ploughing in 63 days.Due to the decreasing of the soil toxicity,Zea mays L.and Eisenia fetida could grow well,which suggested that the bioremediation worked well.
