Abstract
Desulfovibrio vulgaris Hildenborough (DvH) is a gram-negative, anaerobic, sulfate-reducing bacterium (SRB). SRB are capable of using sulfate as a terminal electron acceptor resulting in the production of hydrogen sulfide as an end product. Not only can SRB raise the environmental pH through their production of bicarbonate, but they can also assist in the precipitation of toxic metal ions through their production of hydrogen sulfide and direct transfer of electrons to oxidized forms of toxic heavy metals such as uranium and chromium. With metabolic capabilities such as these, DvH is considered a potential organism for bioremediation and sulfur cycling. However, very little is known about the regulation of these metabolisms.
