Desulfovibrio desulfuricans is a Gram-negative sulfate-reducing bacteria. It is generally found in soils, waters, and the stools of animals, although in rare cases it has been found to cause infection in humans.[2] It is particularly noted for its ability to produce methyl mercury.[3] Since these bacteria are killed by exposure to atmospheric oxygen, the environmental niches most frequently occupied by these bacteria are anaerobic.[4]

Morphology[edit]

Desulfovibrio desulfuricans has been described as a motile, rod-shaped, Gram-negative obligate anaerobe with polar flagella. It measures approximately 3μm by 0.5μm.[5]
