ABSTRACT 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. 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.
