Evaluation of the inhibitory effects of chloroform on ortho-chlorophenol- and chloroethene-dechlorinating Desulfitobacterium strains.

ABSTRACT: Organohalide-respiring Desulfitobacterium strains are believed to play an important role in the bioremediation and natural attenuation of chlorinated aliphatic and aromatic hydrocarbons. However, several studies have reported that chloroform significantly inhibits microbial reductive dechlorination of chloroethene. In this study, we examined the effect of chloroform on several Desulfitobacterium strains, including ortho-chlorophenol-dechlorinating Desulfitobacterium dehalogenans JW/IU-1 and Desulfitobacterium hafniense DCB-2, and also the chloroethene-dechlorinating strain D. hafniense TCE1. In medium containing 3-chloro-4-hydroxyphenylacetate as an electron acceptor, chloroform inhibited the growth of strains JW/IU-1 and DCB-2. Although chloroform did not directly inhibit dechlorination o
