Reduction of Chromate by Desulfovibrio vulgaris and Its c(3) Cytochrome

Appl Environ Microbiol. 1994 Feb;60(2):726-8. doi: 10.1128/aem.60.2.726-728.1994.


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.
