Chlorinated Electron Acceptor Abundance Drives Selection of () Strains in Dechlorinating Enrichment Cultures and Groundwater Environments.

() strains differ primarily from one another by the number and identity of the reductive dehalogenase homologous catalytic subunit A () genes within their respective genomes. While multiple genes have been sequenced, the activity of the corresponding proteins has been identified in only a few cases. Examples include the enzymes whose substrates are groundwater contaminants such as trichloroethene (TCE), -dichloroethene (cDCE) and vinyl chloride (VC).
