Effect of acclimation on methanogenic degradation of chlorophenols
- Univ. of Kentucky, Lexington, KY (United States). Dept. of Civil Engineering
Chlorophenols are highly toxic and persistent in the environment. Several millions of pounds of chlorinated phenols and chlorophenol based compounds are manufactured and used every year. Pentachlorophenol (PCP) and tetrachlorophenols (TCP) are widely used in the paper pulp industry and also as wood preservatives. Chlorophenols are also formed during the disinfection of wastewater containing phenols and in chlorine bleaching processes of cellulose. Anaerobic biodegradation of chlorophenols by anaerobic microbial consortia has been extensively studied by many researchers. Anaerobic biodegradation of chlorophenols occurs through a series of reductive dechlorination, in which the chlorine is replaced by hydrogen at each step. This reductive dehalogenation is of environmental importance because the less chlorinated metabolic products are generally less toxic and more easily degraded by aerobic bacteria. The main objective of this study is to examine the degradation of chlorophenols in both unacclimated and acclimated methanogenic cultures.
