Abstract

The mechanisms of the microbial degradation of crude oil are aerobic and anaerobic biodegradations. The degradation of crude oils in laboratories usually takes place in the presence of oxygen. Anaerobic biodegradation cannot be absolutely simulated in laboratories because of its slow degradation rate. The temperature is a main factor controlling the biodegradation. The laboratory biodegradation effect is the best under about 40℃. After the microbial degradation in laboratory, the crude oil samples have lower saturated hydrocarbon, and higher aromatic hydrocarbon, nonhydrocarbon and asphaltene. Asphaltene is not susceptible to biodegradation and its pyrolysis product and the Ruthenium ion catalyed oxidation product have important role in the oil-oil correlation and oil source correlation for the biodegraded oil.
