Sulfur reducing bacteria

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

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

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

Some bacteria can use both sulfur and sulfate as a source of energy.
