Effect of additional carbon sources on biodegradation of phenol

The biodegradation rate of phenol by Pseudomonas putida ATCC 49451 was optimized by supplementing the growth medium with either yeast extract or glucose. Previous studies had shown that substrate inhibition was severe for P. putida at phenol concentrations above 1000 mg/l. The optimum amount of yeas...

Description
Summary:The biodegradation rate of phenol by Pseudomonas putida ATCC 49451 was optimized by supplementing the growth medium with either yeast extract or glucose. Previous studies had shown that substrate inhibition was severe for P. putida at phenol concentrations above 1000 mg/l. The optimum amount of yeast extract for supplementation was determined to be 1.5 g/l per 750 mg/l of phenol, and the optimum glucose supplementation was 0.8 g/l per 750 mg/l phenol.
