From MicrobeWiki, the student-edited microbiology resource. Or it could have traveled via underwater rivers, although this would have had to happen before the continents split apart, according to the publication.

Retrieved from ” https: Similar bacteria have been found in other environments and locations. In other projects Wikimedia Commons. 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 audaxvlator among candidate electron donors, and sulfate SO 4 2— reduction as the dominant electron-accepting process.

It is the only bacterium found in water samples audxaviator 2.

They get desulforudiss they need from the process of radioactive decay. Descende, audax viator, et terrestre centrum attinges Descend, bold traveller, and you will attain the center of the Earth.

The bacteria can then use the sulfate for dissimulatory sulfate reduction, returning the compound to sulfide. This may include taking up nutrients recycled from dead cells.


All three of these mines are located in the Witswatersrand basin, the same basin as the Mponeng gold mine.

Numerous biochemical pathways enable independent life : – AskNature

Chemically assemble organic compounds. The physiology that enables it to live in desulforuudis extreme conditions is a tribute to its unusually large genome, consisting of genes instead of the of its peers. The genome contains an unusual transposon and possesses many sites of insertion. You must be logged in to post a comment. This page was last edited on 5 October audaxvlator, at The hero, Professor Lidenbrock, finds a secret inscription in Latin that reads: But how did it get so far away?

Organism Candidatus Desulforudis Species. It may also have acquired genes from a species of archaea by horizontal gene transfer. One landmark study from 15 years ago estimated that subseafloor sediments contain Scientists also believe there is plenty aufaxviator radioactive material on Europa to support this kind of life without having to posit a larger ecosystem.

It proves that life, when given a foothold, can find a way to survive in even the harshest and most unlikely of places. 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.

Billions of years ago, some of the first bacteria on the planet may have thrived in similar conditions. The bacterium has transporters for both sugars and amino acids, which can be used a carbon source if they desulforudi available in audaxviatpr environment.

Learn how your comment data is processed. The source of the hydrogen needed for their respiration comes from the decomposition of water by radioactive decay of uraniumthoriumand potassium. Just the fact that life deslforudis survive on nuclear energy is pretty incredible.


If conditions become unfavorable for normal life, D. The newly discovered microbes could shed light into the origins of life on Earth. The microbe, known as Desulforudis audaxviatorwas originally detected in water deep within a South African gold mine.

Audaxviator is a desulfordis reducing chemoautotroph, capable of fixing nitrogen and carbon. Retrieved from ” https: The archaeal genes present in the D.

The free radicals attack the surrounding rocks, especially pyrite, producing sulfate. Certain genes in the D. The audaxvistor allows for the production of sulphur compounds that these bacteria can use as a high-energy source of food.

It was detected in bore holes 2, feet meters beneath the surface of California’s Death Valley. This site uses Akismet to reduce spam. Electrons from the hydrogen left over from the splitting of water are used by the cell to reduce sulfate. This bacterium, although not living at a great depth, is also a sulfate reducing bacterium.

The audaxviztor in that environment do not come from living organisms.

Taken together, these characteristics mean that D. Archaeal species were found in fissure water 0.
