The influence of glucose and fructose on the degradation of 2-chlorophenol by Pseudomonas putida CP1

Pseudomonas putida CP1 grew on 2-chlorophenol when supplied as the sole source of carbon. Chlorophenol degradation was stimulated in the presence of low concentrations of glucose (0.05-1%, w/v). Substrate removal was inhibited and there was a significant fall in pH with concentrations of glucose gre...

Summary:Pseudomonas putida CP1 grew on 2-chlorophenol when supplied as the sole source of carbon. Chlorophenol degradation was stimulated in the presence of low concentrations of glucose (0.05-1%, w/v). Substrate removal was inhibited and there was a significant fall in pH with concentrations of glucose greater than 1.0% (w/v). When the pH was controlled at pH 7.0 inhibition of substrate removal was alleviated. The rate of removal of 2-chlorophenol was greater in the presence of fructose than in the presence of glucose. P. putida CP1 formed clumps of cells when grown on 2-chlorophenol and fructose but not on glucose. When the organism was grown on a combination of 2-chlorophenol and an additional carbon source clumping was present but to a lesser degree.
