Abstract
Reductive dechlorination of chlorinated ethenes by anaerobic bacteria is surmised to follow a pathway wherein chloroalkylcobalamin complexes are reduced to form chlorinated ethene intermediates. The degradation is catalyzed by vitamin B12 and titanium citrate which effects a homolytic cleavage and titanium-catalyzed elimination reaction. This alternative pathway can be manipulated to reduce the release of undesirable intermediates such as vinyl chloride.
