摘要: The biodegradations of phenol and 4-chlorophenol(4-cp)were studied using the mutant strain CTM 2 obtained by the He-Ne laser irradiation on wild-type Candidatropicalis.The results showed that the capacity of the CTM 2 to biodegrade 4-cp was increased up to 400 mg·L-1 within 59.5 h.In the dual-substrate biodegradation,both velocity and capacity of the CTM 2 to degrade 4-cp increased with low-concentration phenol.A total of 400 mg·L-1 4-cp was completely degraded within 50.5 h in the presence of 300 mg·L-1 phenol.The maximum 4-cp biodegradation could reach 440 mg·L-1 with 120 mg·L-1 phenol.Low-concentration 4-cp caused great inhibition on the CTM 2 to degrade phenol.In addition,the kinetic behaviors were described using the kinetic model proposed in this lab.
