Biodegradation of Phenol by AcclimatizedPseudomonas putidaCells Using Glucose as an Added Growth Substrate

Abstract

Biodegradation of phenol, a pollutant derived from many industrial processes, was achieved through acclimatized Pseudomonas putida cells. The strategy to overcome the inhibitory effect of phenol on microbial growth involved the addition of glucose, a conventional carbon source. A factorial experimental design was employed in order to optimize the initial phenol and glucose concentrations. The optimum conditions found were applied in 2-lt bioreactors. The development of acclimatized cells and the use of glucose as an added growth substrate resulted in a significant phenol degradation rate of 60.7 mg L(-1) h(-1) with a complete removal of 1200 mg L(-1) phenol.

Biodegradation of phenanthrene using adapted microbial consortium isolated from petrochemical contaminated environment

“…For pollution abatement, these organic compounds are generally removed through physico-chemical methods. These Conventional chemical or physical technologies have inherent drawbacks due to high operating cost, difficulty in operation and production of secondary pollutants [4]. Biodegradation involving the use of naturally occurring microorganisms presents an alternative, yet better approach for the degradation of PAH [5].…”

Co-metabolism of 2,4-dichlorophenol and 4-Cl-m-cresol in the presence of glucose as an easily assimilated carbon source by Staphylococcus xylosus

“…It has been also reported that bacteria continuously exposed in xenobiotic compounds have improved their degradation abilities [19,20]. In microbial communities, a natural selection between microbial species takes place due to pollution.…”

Degradation of hexahydro‐1,3,5‐trinitro‐1,3, 5‐triazine (RDX) by anaerobic mesophilic granular sludge from a UASB reactor

“…For environmental applications, the addition of organic substrates, such as glucose, yeast extract, and sodium glutamate has been considered a promising method to substantially enhance the degradation rate of pollutants 30. It has been reported that glucose supplement accelerated phenol degradation in an anaerobic reactor 17.…”
