This bacterium, although not living at a great depth, is also a sulfate reducing bacterium. The archaeal genes present in the D. It may also have acquired genes from a species of archaea by horizontal gene transfer.

Desulforudis audaxviator Desulforudis audaxviator Scientific classification Kingdom: Articles with ‘species’ microformats All articles with unsourced statements Articles with unsourced statements from March Taxonbars using multiple manual Wikidata items. Organism Candidatus Desulforudis Species.

Taken together, these characteristics mean that D.

The bacterium has transporters for both sugars and amino acids, which can be used a carbon source if they are available in the environment. Severe nutrient limitation is believed to result in cell doubling times ranging from s to s of years…this organism appeared to possess all of the metabolic capabilities necessary for an independent life-style…radiolytically generated chemical species as providing the energy and nutrients to the system, with formate and H 2 as possessing the greatest potential among candidate electron donors, and sulfate SO 4 2— reduction as the dominant electron-accepting process.


In other words, they are able to use inorganic sources of energy instead of consuming organic molecules as food or using sunlightfix their own carbon rather than rely on plants to convert carbon dioxide to organic compoundsand use chemicals other than oxygen for respiration.

The radiation allows for the production of sulphur compounds that these bacteria can use as a high-energy source of food.

Nonetheless, a nitrogenase is present in the genome… D. All three of these mines are located in the Witswatersrand basin, the same basin as the Mponeng gold mine.

Peptococcaceae Sulphophiles Lithophiles Monotypic bacteria genera Candidatus taxa. This makes it one of the few known organisms that does not depend on sunlight for nourishment, and the only species known to be alone in its ecosystem. The physiology that enables it to live in these extreme conditions is a tribute to its unusually large genome, consisting of genes instead of the of its peers. The hydrogen peroxide reacts with the environmental sulfide to form sulfate. The bacteria can then use the sulfate for dissimulatory sulfate reduction, returning the compound to sulfide.
