Through domestication and enrichment culture, 53 bacterial strains were screened from polluted soil of different sources, among which 2 strains with strong degradation ability were identified.T-2 Strain belongs to Flavobacterium, M-4 Strain, Fusarium . Study on the optimal conditions of T-2 and M-4 for degradating castor-based lubricant was made. The optimal condition of T-2 strain is : 30 °C, pH 7.0, while the best condition for M-4 strain is : 30 °C, pH 6.5 .Research on degradation characteristics of castor-based lubricant of T-2 and M-4 strain shows that adding appropriate nitrogen source prompting degradation of castor-based lubricant ,among which ammonium sulfate is better. Low concentration of surfactants could promote the growth of microorganisms and the degradation of castor-based lubricant, and the optimal concentration of Tween-80 were 600 mg / L and 900 mg / L. Co-substrate culture showed that 0.02% glucose increased the degradation rate of T-2 strain.
