The Characteristics and Kinetics of 4-CP with Pb²⁺ Biodegradation by Fusarium sp.

Abstract:

The effects of Pb²⁺ concentration, pH and additional carbon source on biodegradation of 4-chlorophenol (4-CP) by Fusarium sp. were investigated, and the characteristic and kinetic of 4-CP biodegradation were analyzed. It was concluded that 4-CP biodegradation rate by Fusarium sp. decreased a little at concentration of Pb²⁺ 0.20 mg/L and 4-CP 50 mg/L. The suitable biodegradation pH was range from 6 to 7. Additional carbon source (phenol) might increase the rate of 4-CP biodegradation. The kinetic equations of 4-CP biodegradation were well accord with the zero order reaction equation at different concentration of Pb²⁺.
