Desulfovibrio vulgaris is the best-studied sulfate-reducing microorganism species; the bar in the upper right is 0.5 micrometre long.. Sulfate-reducing microorganisms (SRM) or sulfate-reducing prokaryotes (SRP) are a group composed of sulfate-reducing bacteria (SRB) and sulfate-reducing archaea (SRA), both of which can perform anaerobic respiration utilizing sulfate (SO 2−
The condition indicates a high level of sulfate-reducing bacteria in the water supply. This may be due to the use of well water, poorly treated city water, or water heater contamination. Various methods exist to treat sulfur in water. These methods include Filtration of the water using a carbon filter (useful for very small amounts of hydrogen ...
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.
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. [2] It is particularly noted for its ability to produce methyl mercury. [3]
It is also an anaerobic sulfate-reducing bacterium that is an important organism involved in the bioremediation of heavy metals in the environment. [2] Nitratidesulfovibrio vulgaris is often used as a model organism for sulfur-reducing bacteria [3] and was the first of such bacteria to have its genome sequenced. [4]
However, sulfate-reducing bacteria (SRB) in untreated sewage water tend to produce hydrogen sulfide (H 2 S), which is then oxidized in sulfuric acid (H 2 SO 4) by atmospheric oxygen (abiotic reaction) and by aerobic bacteria present in biofilm (biotic reaction) on the concrete surface above the
Only few taxa are true sulfur-reducing bacteria, using sulfur reduction as the only or main catabolic reaction. [6] Normally, they couple this reaction with the oxidation of acetate, succinate or other organic compounds. In general, sulfate-reducing bacteria are able to use both sulfate and elemental sulfur as electron acceptors. Thanks to its ...
Desulfobacterales are an order of sulfate-reducing bacteria within the phylum Thermodesulfobacteria. [1] The order contains three families; Desulfobacteraceae, Desulfobulbaceae, and Nitrospinaceae. [2] The bacterium in this order are strict anaerobic respirators, using sulfate or nitrate as the terminal electron acceptor instead of oxygen.
