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.

Desulforudis audaxviator – microbewiki

From Wikipedia, the free encyclopedia. The hydrocarbons in that environment do not come from living organisms. It was the only organism found in the area, leading some to label its home as an “ecosystem of one.

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. Descende, audax viator, et terrestre centrum attinges Descend, bold traveller, and you will attain the center of the Earth.

Peptococcaceae Sulphophiles Lithophiles Monotypic bacteria genera Candidatus taxa.

They are motile, sporulating, sulfate reducing chemoautotrophsand are categorized as thermophiles and obligate anaerobes. Taken together, these characteristics mean that D. You must be logged in to post a comment.

Desulforudis audaxviator

Ammonia is thought to be at a high enough concentration to provide a sufficient source of nitrogen. This student page has zudaxviator been curated. Douglas Main, Douglas Main loves the weird 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.


Entry of CO 2 substrate into the cell may be accomplished by its anionic species through a putative carbonate adenosine triphosphate ATP —binding cassette transporter…Formate and CO may serve as alternate, more direct, carbon sources in other fractures when sufficiently abundant.

The bacteria can then use the sulfate for dissimulatory sulfate reduction, returning the compound to sulfide. Organism Candidatus Desulforudis Species. It was detected in bore holes 2, feet meters beneath the surface of California’s Death Valley. The dark shaft of the Mponeng mine in South Africa where microbes were found flourishing audaxvjator rocks up to several miles below the Earth’s surface.

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

desulforudis audaxviator – Genome Result

Nonetheless, a nitrogenase is present in the genome… D. But there’s a problem with this audaxviiator hydrothermal organisms here on Earth still rely on oxygen that is produced by other organisms closer to the surface.

The archaeal genes present in the D. Its complete intolerance of oxygen suggests long-term isolation. All three of these mines are located in the Witswatersrand basin, the same basin as the Mponeng gold mine. Formate and CO may also be used as a carbon source. The bacterium has transporters for both sugars and amino acids, which can be used a carbon source if they are available in the environment.

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 hero, Professor Lidenbrock, finds a secret inscription in Latin that reads: It may also have acquired genes from a species of archaea by horizontal gene dessulforudis.

Keep up with Mother Nature

The universe might be teeming with organisms like Desulforudis. A colony of Desulforudis audaxviator, discovered in a gold mine near Johannesburg, South Africa.

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

The bacterium performs chemotaxis along chemical gradients, and takes up nutrients it needs. Learn What is Biomimicry? Studies found that it relies only on hydrogen and sulfide for food, derived from the breakdown of uranium and other radioactive elements. 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.

Reach Douglas Main at dmain techmedianetwork. Audaxviator is a sulfate reducing chemoautotroph, capable of fixing nitrogen and carbon. 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.

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.
