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. It may also have acquired genes from a species of archaea by horizontal gene transfer.
The archaeal genes present in the D. You must be logged in to post a comment. Recently, scientists have lowered their estimates of the number of microbes that they expect live deep underground. It was detected in bore holes 2, feet meters beneath the surface of California’s Death Valley.
Desulforudis – Wikipedia
All three of these mines are located in the Witswatersrand basin, the same basin as the Mponeng gold mine. But perhaps they should have. Peptococcaceae Sulphophiles Lithophiles Monotypic bacteria genera Candidatus taxa.
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. Audaxviator is a sulfate reducing chemoautotroph, capable of fixing nitrogen ahdaxviator carbon.
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. This site uses Akismet to reduce spam. Certain genes in the D.
Info – Candidatus Desulforudis audaxviator MPC
It has somehow evolved to do without the sun or oxygen. The hydrocarbons in that environment do not come from living organisms. 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 of ice that is also suspected of having hydrothermal vents. The bacterium has transporters for both sugars and amino acids, which can be used a carbon source if they are available in the environment.

Descende, audax viator, et terrestre centrum attinges Descend, bold traveller, and you will attain the center of the Earth.
Retrieved from ” https: The radiation allows for the production of sulphur compounds that these bacteria can use as a high-energy source of food. It is the only bacterium found in water samples obtained 2. The bacteria can then use the sulfate for dissimulatory sulfate reduction, returning the compound to sulfide. Formate and CO may also be used as a carbon source. Organism Candidatus Desulforudis Species. From Wikipedia, the free encyclopedia.

It was the only organism found in the area, leading some to label its home as an “ecosystem of one.
Deep-Earth Microbe from South Africa Appears in California
At MP, where biodensity is low, carbon is fixed from inorganic sources…. Its complete intolerance of oxygen suggests long-term isolation.
Scientists suggest it could have made its way to the surface in the mine’s water, and hitched a ride around the world on currents of air.
Taken together, these characteristics mean that D. A colony of Desulforudis audaxviator, discovered in a gold mine near Johannesburg, South Africa. This bacterium, although not living at a great depth, is audaxviayor a sulfate reducing bacterium.
