The Characteristics of p-Chlorophenol with Cu2+ Biodegradation by Fusarium Sp

The stain ofFusariumsp. used in 4-chlorophenol (4-CP) degradation was isolated in our laboratory. The effects of pH, Cu2+concentration, carbon source on 4-CP degradation rate byFusariumsp. were investigated. The kinetic equation of 4-CP biodegradation was discussed. It was concluded thatFusariumsp. could grow with 4-CP as the sole carbon and energy source. 4-CP concentration of 50mg/L in the Cu2+concentration of 3mg/L could be degraded completely. The capacity of 4-CP degradation was effectively enhanced by the addiction of phenol. Phenol concentration of 200 mg/L in the pH 7 and the Cu2+concentration of 3 mg/L could be degraded completely. Cu2+at high concentration might reduce the biodegradation rate of 4-CP. The kinetic equation of 4-CP biodegradation could well accord with the zero order equation for 4-CP as the sole carbon source with Cu2+coexistence byFusariumsp..
