Starting from strain Z-3, the factors affecting the degradation efficiency of strain Z-3 were explored in order to determine the optimum degradation conditions. The strain was used to simulate the remediation of oily soil in laboratory. The conclusions are as follows: (1) The degradation effect of the strain at higher or lower pH and temperature is not significant. The optimal degradation conditions are determined by experiments: temperature 30℃, pH 7.0, initial salt concentration 9 %, initial crude oil concentration 5mg/mL. (2) The optimal inoculum size of the strain for the simulated repair of oily soil is 106 cfu/g, and the optimum soil water content is 30%.
