Abstract
Dechlorination of Aroclor 1242 by pasteurized microorganisms was inhibited by 2-bromoethanesulfonate (BES), sulfate, molybdate, and ethanesulfonate. C onsumption of these anions and production of sulfide from BES were detected . The inhibition could not be relieved by hydrogen. Taken together these re sults suggest that pattern M dechlorination is mediated by spore-forming su lfidogenic bacteria. These results also suggest that BES may inhibit anaero bic dechlorination by nonmethanogens by more than one mechanism.
