摘要：

A hydrocarbon-degrading strain ZRS was isolated from petroleum-contaminated soils sampled from Xinjiang oil field and identified as Acinetobacter beijerinckii, which could use diesel oil as solo carbon source. The optimal temperature and pH for strain utilizing ethanol was 25 degrees C and 7.2; the optimal concentration of ethanol and the biomass concentration was 4.5% and 10(9) CFU/mL, respectively. Inoculated to artificial seawater which added (NH4)(2)SO(4)2.64g/L, Na(2)HPO(4)1.5 g/L and yeast extract 13 mg/L after 7 days of culture at temperature 25 degrees C, the rate of degradation was 73.9%.
