Ecophysiology and application of dechlorinating anaerobes
Biodegradation of chlorinated ethenes was studied both in laboratory cultures and in the field. Optimal tetrachloroethene (PCE) degradation was accomplished by sequential activity of anaerobic PCE-dechlorinating bacteria and aerobic cometaboic mineralization of dechlorination products (trichloroethene, TCE; cis-1,2-dichloroethene, cDCE; and vinylchloride, VC) by phenol-utilizing microbes. A novel PCE-dechlorinating anaerobic bacterium, Desulfitobacterium sp. strain TCE1, was isolated. Its PCE-dehalogenating activity was controlled by the availability of PCE and alternative electron acceptors sulfite, nitrate and fumarate. Metabolic interactions observed in co-cultures of strain TCE1 and a sulfate reducing Desulfovibrio species included competition for shared electron donors and H{sub 2}-transfer from the sulfate reducer to the dechlorinating anaerobe.
