Acetylene-Fueled Trichloroethene Reductive Dechlorination in a Groundwater Enrichment Culture.

ABSTRACT: In aquifers, acetylene (C₂H₂) is a product of abiotic degradation of trichloroethene (TCE) catalyzed by in situ minerals. C₂H₂ can, in turn, inhibit multiple microbial processes including TCE dechlorination and metabolisms that commonly support dechlorination, in addition to supporting the growth of acetylenotrophic microorganisms. Previously, C₂H₂ was shown to support TCE reductive dechlorination in synthetic, laboratory-constructed cocultures containing the acetylenotroph Pelobacter sp. strain SFB93 and Dehalococcoides mccartyi strain 195 or strain BAV1. In this study, we demonstrate TCE and perchloroethene (PCE) reductive dechlorination by a microbial community enriched from contaminated groundwater a
