Abstract

Phenyl methyl ethers are utilized by Desulfitobacterium hafniense DCB2 and Desulfitobacterium hafniense PCE-S; the methyl group derived from the O-demethylation of these substrates can be used as electron donor for anaerobic fumarate respiration or dehalorespiration. The activity of all enzymes involved in the oxidation of the methyl group to carbon dioxide via the acetyl-CoA pathway was detected in cell extracts of both strains. In addition, a carbon monoxide dehydrogenase activity could be detected. Activity staining of this enzyme indicated that the enzyme is a bifunctional CO dehydrogenase/acetyl-CoA synthase.
