Caption: Desulfovibrio vulgaris - Gram-negative, anaerobic, sulfate-reducing bacterium. It is a curved rod-shaped bacterium that occurs in diverse environments including: soil, animal intestines, feces, fresh water and salt water. Desulfovibrio vulgaris has the ability to reduce toxic and radioactive metals to their insoluble forms. This species breaks down metals and can corrode machinery; it also breaks down pollutants and could potentially clean up environmental toxins. The distinguishing characteristics of Desulfovibrio species are that they contain desulfoviridin. Desulfovibrio species oxidize their energy source to that of acetate and excrete this as their end product. Some Desulfovibrio species have in recent years been shown to have bioremediation potentials for toxic radionuclides such as uranium by a reductive bioaccumulation process.
