Desulfovibrio desulfuricans

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] Also the 'reductive glycine pathway', a seventh route for organisms to capture CO2, was discovered in this species.[4] Since these bacteria are killed by exposure to atmospheric oxygen, the environmental niches most frequently occupied by these bacteria are anaerobic.[5] Desulfovibrio desulfuricans 27774 was reported to produce gene transfer agents[6]
