1,2-dicholorethane-dechlorinating enrichment culture

Microbial-mediated reductive dechlorination has been recognized as an environmental-friendly strategy for the remediation of 1,2-DCA-contaminated sites. In this study, we have developed an anaerobic microbiota from 1,2-DCA-contaminated groundwater capable of converting 1,2-DCA into no-toxic ethylene with a high dechlorination rate. Here, a syntrophic consortium capable of sustainedly dechlorinating 1,2-DCA to non-toxic ethylene without addition of exogenous B12 or vitamins was obtained.
