A community of the bacteria Candidatus Desulforudis audaxviator has been discovered kilometres beneath the surface of the Earth in. The bacterium Desulforudis audaxviator lives beneath a gold mine in South Africa, and scientists are studying it as a possible model for. 1.

Ammonia is thought to be at a high enough concentration to provide a sufficient source of nitrogen. It has somehow evolved to do without the sun or oxygen. Desulforudis, however, lives in a far more isolated system.

Desulforudis audaxviator

The radiation allows for the production of sulphur compounds that these bacteria can use as a high-energy source of food. From Wikipedia, the free encyclopedia. The hydrogen peroxide reacts with the environmental sulfide to form sulfate. Few organisms are similar to Desulforudis audaxviator in that they are anaerobic chemolithoautotrophs.

Info – Candidatus Desulforudis audaxviator MPC

They get everything they need from the process of radioactive decay. The genome contains an unusual transposon and possesses many sites of insertion.

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. Audaxviator is a sulfate reducing chemoautotroph, audxxviator of fixing nitrogen and carbon. From MicrobeWiki, the student-edited microbiology resource.

The dark shaft of the Mponeng mine in South Africa where microbes were found flourishing in rocks up to several miles below the Earth’s surface. Billions of years ago, some of the first bacteria on the planet may have thrived in similar conditions.

Approximately audaxvoator micrometres in length, it has survived for millions of years on chemical food sources that derive from the radioactive decay of minerals in the surrounding rock.

The hero, Professor Lidenbrock, finds a secret inscription in Latin that reads: This organism is so strange that researchers are now studying it as a possible model for extraterrestrial life, audaxviatr on worlds far away from the life-giving energy of a star.


It may also have acquired genes from a species of archaea by horizontal gene transfer. Douglas Main, Douglas Main loves the aaudaxviator and wonderful world of science, digging into amazing Planet Earth discoveries and wacky animal findings from marsupials mating themselves to death to zombie worms to tear-drinking butterflies for Live Science.

The hydrocarbons in that environment do not come from living organisms. It proves that life, when given a foothold, can find a way to survive in even the harshest and most unlikely of places. The bacteria can then use the sulfate for dissimulatory sulfate reduction, returning the compound to sulfide. Nonetheless, a nitrogenase is present in the genome… D. The universe might be teeming with organisms like Desulforudis. The archaeal genes present in the D. 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 desulfogudis, 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.

Learn What is Biomimicry? Or audazviator could have traveled via underwater rivers, although this would have had to happen before the continents split apart, according to the publication. Comments Cancel reply You must be logged in to post a comment. Electrons from the hydrogen left over from the splitting of water are used by the cell to reduce sulfate.

Descende, audax viator, et terrestre centrum attinges Descend, bold traveller, and you will attain the center of the Earth. Chemically assemble organic compounds. The bacteria use the sulfate to synthesise ATP [adenosine triphosphate], the nucleotide responsible for energy storage in cells. Certain genes in the D. You must be logged in to post a comment.

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. But perhaps they should have.

The bacterium has transporters for both sugars and amino acids, which can be used a carbon source if they are available in the environment. Watch Interactive Report Edit Summary.

But sudaxviator did it get so far away? It was detected in bore holes 2, feet meters beneath the surface of California’s Death Valley. If conditions become unfavorable for normal life, D. But there’s a problem with this model; hydrothermal organisms here on Earth still rely on oxygen that is produced by other organisms closer to the surface. Organism Candidatus Desulforudis Species.

Scientists also believe there is audaxvistor of radioactive material on Europa to support this kind of life without having to posit a larger ecosystem.

Peptococcaceae Sulphophiles Lithophiles Monotypic bacteria genera Candidatus taxa. Reach Douglas Main at dmain techmedianetwork. It is the only bacterium found in water samples obtained 2.

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.

One place where we might find aliens that are similar to Desulforudis audaxviator is right here in our own solar system:
