| Abstract: | Due to the oil pollution problem, high-efficiency degradation strains of petroleum hydrocarbon are researched. The degradation performances of the strains H4 is studied. The optimum conditions are determined for the cyclohexane degradation by efficient strains H4. The results are： the initial concentration of cyclohex- ane is 2.49 g/L, the culture temperature is 28 ℃, pH is 6, the concentration of the strain H4 is about 9×105 mL-1 in the liquid culture medium, the volume of liquid culture medium is 100 mL, the speed of rotary shaker is 120 r/min, and the degradation rate is 70.1% in 96 h. |
