Effect of Conventional Carbon Sources on Phenol Degradation by Bacillus sp. CDQ


Article Preview

The influence on the growth and phenol biodegradation of Bacillus sp. CDQ by three different conventional carbon sources were investigated. The results indicated that conventional carbon sources certainly affected the growth of strain CDQ and the biodegradation of phenol. Under the concentration of 1.5 to 3 g L-1, contrasting to the comparison, glucose improved the growth of the Bacillus sp. CDQ but inhibited the phenol biodegradation by Bacillus sp. CDQ. And the effect of inhibition increased with increasing glucose concentration. Below 1.5 g L-1, the rate of phenol removal increased with the amount of glucose added. Phenol biodegradation rate obviously decreased in the presence of sodium acetate. Lactose can significantly improve the rate of phenol biodegradation. However, no noticeable improvement on the removal rate of phenol was observed under different concentrations of lactose.
