RESUMO
Microbially mediated reductive dechlorination of polychlorinated biphenyls (PCBs) in anaerobic sediments has been observed during laboratory experiments. Reductive dechlorination is a two-electron transfer reaction which involves the release of chlorine as a chloride ion and its replacement on the aromatic ring by hydrogen. The exact mechanism of the electron transfer for PCBs is unknown; however, this work shows that the source of the hydrogen atom is the proton (H+) from water.
