''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.
Like other sulfate-reducing bacteria, ''Desulfovibrio'' was long considered to be
obligately anaerobic. This is not strictly correct: while growth may be limited, these bacteria can survive in O
2-rich environments. These types of bacteria are known as
aerotolerant.
Some'' Desulfovibrio'' species have in recent years been shown to have
bioremediation potential for toxic
radionuclides such as uranium by a reductive
bioaccumulation
Bioaccumulation is the gradual accumulation of substances, such as pesticides or other chemicals, in an organism. Bioaccumulation occurs when an organism absorbs a substance at a rate faster than that at which the substance is lost or eliminated ...
