Abstract: A strain of crude oil degrading bacteria OA58 was isolated from a crude oil contaminated marine sponge from Dalian Bay, China. According to the 16S rRNA genes sequences analysis, physiological and biochemical characterizations, the strain OA58 was identified as Streptomyces exfoliatus. When the initial concentration of crude oil was 1 g/L, the strain OA58 could consume 83% of the crude oil in 14 days, indicating a good potential of degradation capability of crude oil.

Key words: crude oil, marine sponge, identification, biodegradation
