Reduction of Chromate by <i>Desulfovibrio vulgaris</i> and Its <i>c</i> ₃ Cytochrome

Abstract

Washed cell suspensions of Desulfovibrio vulgaris rapidly reduced Cr(VI) to Cr(III) with H(2) as the electron donor. The c(3) cytochrome from this organism functioned as a Cr(VI) reductase. D. vulgaris may have advantages over previously described Cr(VI) reducers for the bioremediation of Cr(VI)-contaminated waters.
