General Information: Dechlorinates tetrachloroethene. This organism was isolated from environments contaminated with organic chlorinated chemicals such as tetrachloroethene (PCE) and trichloroethane (TCE), common contaminants in the anaerobic subsurface. There are at least 15 organisms from different metabolic groups, halorespirators, acetogens, methanogens and facultative anaerobes, that are able to metabolize PCE. Some of these organisms couple dehalogenation to energy conservation and utilize PCE as the only source of energy while others dehalogenate tetrachloroethene fortuitously. This non-methanogenic, non-acetogenic culture is able to grow with hydrogen as the electron donor, indicating that hydrogen/PCE serves as an electron donor/acceptor for energy conservation and growth. This organism can only grow anaerobically in the presence of hydrogen as an electron donor and chlorinated compounds as electron acceptors. Dehalococcoides ethenogenes is typically found at sites contaminated with chlorinated solvents, and have been independently isolated in dozens of sites across the USA.
