[Objective] High efficient strains degrading pollutants from cooking fume were screened out and their degradation properties were studied. The research could provide basis for the use of microorganisms to carry out environmental restoration. [Method] The selective medium containing in Jin long oil was used to isolate strains degrading pollutants from cooking fume. The best conditions for degradation was explored. [Result] Two strains were isolated and screened which could degrade oil smoke from contaminant soil. They were named as KD-1 and KD-2. Two strains had different degrading activities and mixed strain showed higher degrading activity. The degradation proportion of the mixed strain to pollutants from cooking fume contaminant was 87.11%. Microbes could only use oil waste as source of the carbon to grow. The optimum condition of this strain microbial degrading pollutants from cooking fume was as follows: pollutants from cooking fume was 80 g/L, NaNO_3 concentration was 2 g/L, temperature was 40 ℃, and shaking speed was 220 r/min. [Conclusion] The strains degrading pollutants from cooking fume thus obtained was a valuable material for the application of using bio-method to oil fume pollutants.
