ABSTRACT
A mixed, anaerobic microbial enrichment culture, AMEC-4P, was developed that uses lactate as the electron donor for the reductive dechlorination of tetrachloroethene (PCE) to ethene. AMEC-4P consistently and completely converted 2 mM PCE to cis-1,2-dichloroethene (cis-DCE) within 13 days, and the intermediate, cis-DCE, was then completely dechlorinated to ethene after 130 days. Dechlorination rates for PCE to cis-DCE, cis-DCE to VC, and VC to ethene were 243, 27, and 41 µmol/l/day, respectively. Geobacter lovleyi and a Dehalococcoides sp. were identified from their 16S rRNA sequences to be the dominant phylotypes in AMEC-4P.
