But perhaps they should have.

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

This bacterium, although not living at a great depth, is also a sulfate reducing bacterium. The genome contains an unusual transposon and possesses many sites of insertion.

Desulforudis audaxviator

Archaeal species were found in fissure water 0. The universe might be teeming with organisms like Desulforudis. One landmark study from 15 years ago estimated that subseafloor sediments contain 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.

But how did it get so far away? Electrons from the hydrogen left over from the splitting of water are used by the cell to reduce sulfate.


The free radicals attack the surrounding rocks, especially pyrite, producing sulfate. Learn how your comment data is processed. Desulforudis, however, lives in a far more isolated system.

The hero, Professor Lidenbrock, finds a secret inscription in Latin that reads: Recently, scientists have lowered their estimates of the number of microbes that they expect live deep underground. 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.

This may include taking up nutrients recycled from dead cells.

Formate and CO may also be used as a carbon source. 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.

The bacteria use the sulfate to synthesise ATP [adenosine triphosphate], the nucleotide responsible for energy storage in desulfogudis. From Wikipedia, the free encyclopedia. Reach Douglas Main at dmain techmedianetwork.

A colony of Desulforudis audaxviator, discovered in a gold mine near Johannesburg, South Africa. It proves that life, when given a foothold, can find a way to survive in even the harshest and wudaxviator unlikely of places.

A shadowy microbe first found 2 miles 3.

Audaxviator is a sulfate reducing chemoautotroph, capable of fixing nitrogen and carbon. Just the fact that life can survive on nuclear energy is pretty incredible. They get everything they need from the process of radioactive decay.

At MP, where biodensity is low, carbon is fixed from inorganic sources….
