dehalogenation of tetrachloroethene results in a similar extent of C and Cl isotope fractionation, and in similar dual element isotope slopes for PceA enzyme and for abiotic dehylogenation by corrinoids. Catalytic dehalogenation by enzymes and different corrinoids display mechanistic and/or kinetic differences |

in homogeneous aqueous solution containing titanium(III) citrate or titanium(III)-nitrilotriacetic acid as bulk electron donor, cobalamin, cobinamide, and cobamide are effective electron transfer mediators for the reduction of tetrachloroethene, trichloroethene, and trichlorofluoroethene. For a given chlorinated ethene, the reaction rate varies only slightly with pH and type of corrinoid present and is about 5 and 50 times faster for tetrachloroethene as compared to trichlorofluoroethene and trichloroethene, respectively. The first and rate-limiting step of the reduction of tetrachloroethene, trichloroethene, and trichlorofluoroethene by super-reduced corrinoids is a dissociative one-electron transfer yielding the corresponding vinyl radicals |
