In 2,4,6-trichlorophenol-amended cultures, cprA2 and cprA3 were upregulated, as was cprA5, but concomitantly with the appearance of 2,4-dichlorophenol (DCP). In 3,5-DCP-amended cultures, only cprA5 was upregulated. In pentachlorophenol-amended cultures grown for 12 h, cprA2 and cprA3 were upregulated but not cprA5. cprA4 was not upregulated significantly in cultures containing any tested chlorophenols.Applied and environmental microbiology6261-4https://www.ebi.ac.uk/biostudies/studies/S-EPMC3165378biostudies-literatureQuantitative analysis of the relative transcript levels of four chlorophenol reductive dehalogenase genes in Desulfitobacterium hafniense PCP-1 exposed to chlorophenols.PMC3165378Bisaillon ABeaudet RLepine FVillemur R38falseQuantitative analysis of the relative transcript levels of four chlorophenol reductive dehalogenase genes in Desulfitobacterium hafniense PCP-1 exposed to chlorophenols.Relative to those of unexposed cultures, the transcript levels of the four CprA-type reductive dehalogenase genes (cprA2, cprA3, cprA4, and cprA5) in Desulfitobacterium hafniense PCP-1 were measured in cultures exposed to chlorophenols.
