Reductive dechlorination in combination with the elimination of chloride has been demonstrated in a strain of Clostridium rectum (Ohisa et al. 1982) y-hexachlorocyclohexene formed 1,2,4-trichlorobenzene and y-l,3,4,5,6-pentachlorocyclohexene formed 1,4-dichlorobenzene (Figure 7.69). It was suggested that this reductive dechlorination is coupled to the synthesis of ATP, and this possibility has been clearly demonstrated during the dehalogenation of 3-chlorobenzoate coupled to the oxidation of formate in Desulfomonile tiedjei (Mohn and Tiedje 1991). Combined reduction and elimination has also been demonstrated in methanogenic cultures that transform 1,2-dibromoethane to ethene and 1,2-dibromoethene to ethyne (Belay and Daniels 1987).

Cells of Desulfomonile tiedjei induced by growth with 3-chlorobenzoate were able to partially dechlorinate polychlorinated phenols, specifically at the 3-position, whereas the monochlorophenols were apparently resistant to dechlorination (Mohn and Kennedy 1992). Details of the reductase have already been described in Part 1 of this chapter.

A comparable reductive dechlorination is used by a pentachlo-rophenol-degrading Flavobacterium sp. and the enzyme has been purified the successive dechlorinations to form 2-chloro-l,4-dihy-droxybenzene are probably mediated by a glutathione S-trans-ferase system (Xun et al. 1992c). It should be noted that the evidence so far shows that the enzyme involved in this reaction is distinct from that involved in the anaerobic dechlorination of 3-chloroben-zoate by Desulfomonile tiedjei DCB-l(Ni et al. 1995) that is discussed further in Section 6.6.
