Abstract
Studies of the Effects of Co-substrates on Biodegradation Kinetics of 4-Chlorophenol Using Response Surface Methodology (RSM)
Highlights
Untreated effluent containing chlorophenols such as 4-chlorophenol (4-CP) from industries such as pesticides and oil refining sectors poses a serious threat to the receiving environment.[1,2,3] The United States Environmental Protection Agency has listed these chlorophenols as priority pollutants in view of their high toxicity and carcinogenicity.[3]
Similar observation was reported by Loh and Tan, in which better performance of phenol degradation was observed in the presence of 0.2 g l to 2 g l yeast extract as co-substrate, the biodegradation rate declined at higher concentration of yeast extract.[6]
This study investigated the effect of glucose or sucrose as co-substrate on 4-CP biodegradation kinetics
Summary
Untreated effluent containing chlorophenols such as 4-chlorophenol (4-CP) from industries such as pesticides and oil refining sectors poses a serious threat to the receiving environment.[1,2,3] The United States Environmental Protection Agency has listed these chlorophenols as priority pollutants in view of their high toxicity and carcinogenicity.[3]. This process is eco-friendly and energy-efficient with achievable complete mineralisation of chlorophenols.[8]
