Desulfovibrio

Desulfovibrio is a genus of Gram-negative sulfate-reducing bacteria. Desulfovibrio species are commonly found in aquatic environments with high levels of organic material, as well as in water-logged soils, and form major community members of extreme oligotrophic habitats such as deep granitic fractured rock aquifers. They're also found in the guts of beetles, such as Melolontha melolontha, where they perform sulfate reduction.

High amounts of Desulfovibrio bacteria have been associated with inflammatory bowel disease, bacteremia infections, Parkinson's disease, breast cancer, and melanoma.

Some Desulfovibrio species have in recent years been shown to have bioremediation potential for toxic radionuclides such as uranium by a reductive bioaccumulation process, such as converting highly water-soluble U(VI) to relatively insoluble U(IV) precipitate, thus removing the toxic uranium from contaminated water.
