Census - Chlorinated Phenols Remediation

Under anaerobic conditions, pentachlorophenol (PCP) can serve as an electron acceptor for some Desulfitobacterium and Dehalococcoides species. In each case however, complete reductive dechlorination of PCP to phenol was not observed. Instead, PCP dechlorination by Dehalococcoides resulted in the production of a mixture of dichloro- and monochlorophenols. Likewise, Desulfitobacterium strain PCP-1 dechlorinates PCP to 3-chlorophenol but other Desulfitobacterium species are only capable of ortho-dechlorination. Thus the net production of lesser chlorinated phenol must be considered when evaluating reductive dechlorination as a mechanism for PCP biodegradation. QuantArray®-Chlor includes quantification of all Targets listed in the table below. Alternatively, CENSUS® qPCR can be performed to quantify a select subset such as Dehalococcoides and Desulfitobacterium.
