| Abstract |
Representatives from the genus Dehalogenimonas have the metabolic capacity to anaerobically transform a variety of environmentally important polychlorinated aliphatic compounds. In light of the recent isolation of additional strains, description of a new species, and an expanded number of uncultured DNA sequences, PCR primers and protocols intended to uniquely target members of this organohalide-respiring genus were reevaluated. Nine of fourteen primer combinations reported previously as genus-specific failed to amplify 16S rRNA genes of recently isolated Dehalogenimonas strains. Use of alternative combinations or modified genus-specific primers, however, allowed detection of all presently known Dehalogenimonas strains. Use of a modified primer set in qPCR revealed an approximately two-order of magnitude increase in concentration of Dehalogenimonas 16S rRNA gene copies following subsurface injection of electron donors at a Louisiana Superfund site, demonstrating the utility of the newly developed protocol and suggesting that the genus Dehalogenimonas can respond to biostimulation remediation strategies in a manner similar to that previously reported for other dechlorinating genera such as Dehalococcoides.
