【 摘 要 】

In order to address the complex cometabolic degradation of toxic compounds, batch experiments on the biodegradation of 2-chlorophenol (2-CP) and phenol by Pseudomonas putida were carried out. The experimental results show that 2-CP has an inhibitory effect on cell growth and phenol degradation, which demonstrates that the interaction between substrates affects cell growth and substrate degradation. A kinetic model of cell growth and substrate transformation was also developed. The square of the correlation coefficient from the experiment was 0.97, indicating that this model properly simulates the cometabolic degradation of 2-CP and phenol.
