Abstract:
Ralstonia metallidurans CH34 was isolated from the deposit of a znic factory .The degradation of phenol by R .metallidurans CH34 was investigated. The results showed that R . metallidurans CH34 possesses high ability to degrade phenol with the biodegradation rate constant of 0.33 . The optimal pH , temperature and volume of medium for phenol degradation are pH 7.0 , 30℃ , and 20%(v/v), respectively . In addition , this strain retains its ability to degrade phenol in the presence of high concentration of heavy metal ion .The sodium citrate , sodium succinate can enhance the degradation of phenol.
