Desulfovibrio desulfuricans is a Gram-negative sulfate-reducing bacteria. It is generally found in soil, water, and the stools of animals, although in rare cases it has been found to cause infection in humans. It is particularly noted for its ability to produce methyl mercury. The reductive glycine pathway, a seventh route for organisms to capture CO₂, was discovered in this species. Since these bacteria are killed by exposure to atmospheric oxygen, the environmental niches most frequently occupied by these bacteria are anaerobic. Desulfovibrio desulfuricans 27774 was reported to produce gene transfer agents.

Morphology

Desulfovibrio desulfuricans has been described as a motile, rod-shaped, Gram-negative obligate anaerobe with polar flagella. It measures approximately 3 μm by 0.5 μm.
