Ammonia is thought to be at a high enough concentration to provide a sufficient source desulforudsi nitrogen. The hydrogen peroxide reacts with the environmental sulfide to form sulfate. The source of the hydrogen needed for their respiration comes from the decomposition of water by radioactive decay of uraniumthoriumand potassium.

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.

Similar bacteria have been found in other environments and locations. The hydrocarbons in that environment do not come from living organisms.

Retrieved from ” https: This may include taking up nutrients recycled from dead cells. Audaxviator is a sulfate reducing chemoautotroph, capable of fixing ddsulforudis and carbon.


Personal tools Log in. 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.

Approximately four 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 newly discovered microbes could shed light into the origins of life on Earth.

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 potential among candidate electron donors, and sulfate SO 4 2— reduction as the dominant electron-accepting process.

Retrieved from ” https: The bacterium has transporters for both sugars and amino acids, which can be used a carbon source if they are available in the environment. Nonetheless, audaxviatog nitrogenase is present in the genome… D. Descende, audax viator, et terrestre centrum attinges Descend, bold traveller, and you will attain the center of the Earth.


This bacterium, although not living at a great depth, is also a sulfate reducing bacterium. Archaeal species were found in fissure water 0. They are motile, sporulating, sulfate reducing chemoautotrophsand are categorized as thermophiles and obligate anaerobes.

This student page has not desulgorudis curated. The bacteria can then use the sulfate for dissimulatory sulfate reduction, returning the compound to sulfide. Taken together, these characteristics mean that D.

This page was last edited on 5 Octoberat At MP, where biodensity is low, carbon is fixed from inorganic sources….

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 transfer. Billions of years ago, some of the first bacteria on the planet may have thrived in similar conditions.
