Sulfur-reducing bacteria

Sulfur-reducing bacteria

Sulfur-reducing bacteria get their energy by reducing elemental sulfur to hydrogen sulfide. They couple this reaction with the oxidation of acetate, succinate or other organic compounds.

Several types of bacteria and many non-methanogenic archaea can reduce sulfur.

Some bacteria—such as "Proteus", "Campylobacter", "Pseudomonas" and "Salmonella"—have the ability to reduce sulfur, but can also use oxygen and other terminal electron acceptors.Others, such as "Desulfuromonas", use only sulfur.

These bacteria can be used in industrial processes to generate hydrogen sulfide for the precipitation of metals.

Some bacteria can use both elemental sulfur and sulfate as a source of energy. See sulfate-reducing bacteria.
