Abstract	A strain of microbacterium sp. 3-28 was screened to biodegrade the asphaltene fraction of crude oil in Bohai Oilfield and Karamay Oilfield. The effects of microbe degradation on the components and composition among the saturated hydrocarbons, aromatic hydrocarbons, resins and asphaltene fractions in oils were analyzed. The results showed that the physiochemical characteristics of crude oil changed obviously under the effect of microbacterium sp. 3-28. The viscosity of oils in Suizhong 36-1 and Karamay oilfields decreased by 24.9% and 32.4% respectively, and the freezing points decreased by 5.2°C and 7.7°C respectively. The saturated hydrocarbons and aromatic hydrocarbons increased by 8.0% and 21.4% respectively, and the asphaltene fraction decreased by 37.5% and 58.7% respectively. The fraction ratio of short chain to long chain of the saturated hydrocarbon got higher after biodegradation of oil. The quality of the thickened oil was greatly improved.
