Study on Degradation Performances of Klebsiella Spp. For Cyclohexane
Degradation performances of Klebsiella spp. for Cyclohexane was studied by using the method of single factor in the paper. The influences of temperature, pH, initial concentration of Cyclohexane, oxygen supply, culture time etc. were studied and the optimum conditions were determined. The results show that the activated strains of Klebsiella spp. are inoculated in the liquid culture medium of 100 ml which contained cyclohexane, the initial concentration of cyclohexane is 2490 mg/L, the culture temperature is at 28°C, pH is 6, the number of Klebsiella spp. is about 9×105ml-1in the liquid culture medium, the speed of rotary shaker is 120 r/min, and the degradation rate of Cyclohexane reaches 70.1% in 96 hr. The results could provide the theoretical basis in the field of pollution treatment of petroleum hydrocarbons.
