Abstract In this research, the response surface method designed by Box-Behnken was used to study the effect of temperature, pH value and TPH concentration on the biodegradation of Enterobacter sp. S-1contaminated soil. The value of determination coefficient (R2=0.9565) by analysis of variance (ANOVA) indicated a satisfactory agreement between the quadratic model and the experimental data. It was found that TPH degradation rate was more significantly affected (P < 0.0006) by temperature compared with other two parameters. In the temperature of 30 °C, pH value of 7.14 and TPH concentration was 4.83 g/L, the best degradation rate was 81.63%.
