Desulfovibrionia

Desulfovibrionia is a phylum of anaerobic bacteria that are characterized by their ability to perform sulfate reduction. This means they can use sulfate as a terminal electron acceptor during respiration, a process that releases energy. These microorganisms are found in a wide range of anoxic environments, including marine sediments, freshwater sediments, and the digestive tracts of animals. Their metabolic activity plays a significant role in the global sulfur cycle, contributing to the cycling of sulfur compounds.

Members of Desulfovibrionia are typically rod-shaped and motile, often possessing flagella. They are chemoorganoheterotrophs, meaning they obtain energy by oxidizing organic compounds and use organic carbon as their primary source of carbon. The diversity within this phylum is considerable, with various genera and species identified based on their genetic makeup and metabolic capabilities. While some Desulfovibrionia species are primarily found in specific environmental niches, others exhibit broader distribution. Research into Desulfovibrionia continues to uncover their ecological importance and potential biotechnological applications, particularly in bioremediation and the production of valuable biochemicals.
