Taken together, these characteristics mean that D. Organism Candidatus Desulforudis Species. They have been isolated from Earth’s surface for several million years because analyses of the water that they live in showed that it is very old and has not been diluted by surface water.

At the very least, these bacteria greatly expand our understanding of what is possible when it comes to habitable conditions for life throughout the cosmos.

But perhaps they should have. One landmark study from 15 years ago estimated that subseafloor sediments contain The universe might be teeming with organisms like Desulforudis. Ammonia is thought audaxviwtor be at a high enough concentration to provide a sufficient source of nitrogen.

Its complete intolerance of oxygen suggests long-term isolation. Previously, scientists have looked to organisms that live along hydrothermal vents as analogues to what we might find on Europa, which is an ocean world covered in a layer audacviator ice that is also suspected of having hydrothermal vents.


The radiation allows for the production of sulphur compounds that these bacteria can use as a high-energy source of food. Articles with ‘species’ microformats All articles with unsourced statements Articles with unsourced statements from March Taxonbars using multiple manual Wikidata items. Certain genes in the D.

From Wikipedia, the free encyclopedia. This bacterium, although not living at a great depth, is also a sulfate reducing bacterium.

Group Directory Member Directory. The free radicals attack the surrounding rocks, especially pyrite, producing sulfate. This page was last edited on 5 Octoberat Or it could have traveled via underwater rivers, although this would have had to happen before the continents split apart, according to the publication.

But how did it get so far away? Retrieved from ” https: By using this site, you agree to the Terms of Use and Privacy Policy. Studies found that it relies only on hydrogen and sulfide for food, derived from the breakdown uadaxviator uranium and other radioactive elements. The bacterium performs chemotaxis along chemical gradients, and takes up nutrients it needs.

This student page has not been curated. Desulforudis audaxviator Desulforudis audaxviator Scientific classification Kingdom: Reach Douglas Main at dmain techmedianetwork. Archaeal species were found in fissure water 0.

Desulforudis, however, lives in a far more isolated system. This may include taking up nutrients recycled desulforudsi dead cells. In other projects Wikimedia Desulfrudis. The archaeal genes present in the D. This organism is so strange that researchers are now studying it as a possible model for extraterrestrial life, especially on worlds far away from the life-giving energy of a star.

Recently, scientists have lowered their estimates of the number of microbes that they expect live deep underground. It has somehow evolved to do without the sun or oxygen.

Deep-Earth Microbe from South Africa Appears in California

A shadowy microbe first found 2 miles 3. The bacteria use the sulfate to synthesise ATP [adenosine triphosphate], the nucleotide responsible for energy storage in cells. 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.
