Sulfurreducens

Sulfurreducens is a genus of obligately anaerobic sulfate-reducing bacteria. These microorganisms are characterized by their ability to respire by reducing sulfate to sulfide, a process that yields energy for their growth. They are found in a variety of anoxic environments, including marine sediments, freshwater sediments, and subsurface environments. Sulfurreducens species play a significant role in the global sulfur cycle by mediating the conversion of organic and inorganic sulfur compounds.

The genus Sulfurreducens was first described in 2003, with the type species *Sulfurreducens cadaveris*. Members of this genus are typically rod-shaped and motile, possessing flagella. They can ferment a range of organic substrates, using sulfate as the terminal electron acceptor. The metabolic activity of sulfurreducens contributes to the characteristic odor of hydrogen sulfide in environments where they are abundant. Their presence and activity are important indicators of anoxic conditions and can influence the geochemistry of their habitats. Research into Sulfurreducens continues to explore their ecological roles and potential applications, such as in bioremediation.
