Synergistic Bioremediation of Chlorinated Ethenes by Dehalococcoides mccartyi CWV2 and Nitratidesulfovibrio liaohensis KPS: The Role of Biogenic FeS

This study shows that ferrous alleviates hydrogen sulfide toxicity from sulfate reduction through biogenic ferrous sulfide (FeS) formation, thereby restoring Dehalococcoides mccartyi activity and enhancing trichloroethene dechlorination to ethene.
