主　　题：crude oil degradation mixed strains oilfield wastewater degradation characteristics 

摘      要：A total of 14 halophilic hydrocarbon-degrading strains were isolated from crude oil-contaminated sites,using petroleum as the sole carbon and energy *** these,four highly efficient strains were selected to create the mixed bacterial agent *** four strains were identified through 16S rRNA gene-based sequencing as belonging to Acinetobacter,Bacillus paramycoides,Rhodococcus sp.,and Enterobacter sp.,*** optimal cultivation time for the mixed consortium XH-1 was found to be 48 h,and a nitrogen-phosphorus molar ratio of 10:1 was determined to be beneficial for crude oil ***-1 showed notable crude oil degradation even at a salinity of up to 30 g/L,with little inhibition observed at sulfide concentrations as high as 150 mg/L and initial oil concentrations of 500 mg/*** chromatography analysis revealed that XH-1 was able to efficiently degrade C9–C29 ***,a bio-contact oxidation reactor enhanced by XH-1 showed promising results in treating oilfield *** findings suggest that XH-1 can be applied for the treatment of oilfield wastewater.
