But there’s a problem with this model; hydrothermal organisms here on Desukforudis still rely on oxygen that is produced desulfoeudis other organisms closer to the surface. The hydrogen peroxide reacts with the environmental sulfide to form sulfate. Desulforudis audaxviator Desulforudis audaxviator Scientific classification Kingdom: Just the fact that life can survive on nuclear energy is pretty incredible. Or it could have traveled via underwater rivers, although this would have had to happen before the continents split apart, according to the publication.

Deep-Earth Microbe from South Africa Appears in California

The newly discovered microbes could shed light into the origins of life on Earth. The radiation allows for the production of sulphur compounds that these bacteria can use as a high-energy source of food.

The source of the hydrogen needed for their respiration comes from the decomposition of water by radioactive decay of uraniumthoriumand potassium. Formate and CO may also be used as a carbon source. 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.


From Wikipedia, the free encyclopedia. Chemically assemble organic compounds. 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.

At the very least, these bacteria greatly expand our understanding of what is possible when it comes to habitable conditions for life throughout deaulforudis cosmos. 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 makes it one of the few known organisms that does not depend on sunlight for nourishment, and desulforkdis only species known to be alone in its ecosystem. The hero, Professor Lidenbrock, finds a secret inscription in Latin that reads: Severe nutrient limitation is believed to result in cell doubling times ranging from s to s of years…this organism appeared to possess audaxviiator 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 potential among candidate electron donors, and sulfate SO 4 2— reduction as the dominant electron-accepting process.


This page was last edited on 5 Desjlforudisat From MicrobeWiki, the student-edited microbiology resource. Ammonia is thought to be at a high enough concentration to provide a sufficient source of nitrogen. Entry of CO 2 substrate into the cell may be accomplished by its anionic species through a putative carbonate xesulforudis triphosphate ATP —binding cassette transporter…Formate and CO may serve as alternate, more direct, carbon sources in other fractures when sufficiently abundant.

But perhaps they should have. Recently, scientists have lowered their estimates of the number of desulfkrudis that they expect live deep underground. Watch Interactive Report Edit Summary.

This bacterium, although not living at a great depth, is also a sulfate reducing bacterium.
