Desulforudis audaxviator is a monotypic bacteriawhich lives in depths from 1. It is the only audaxviatod found in water samples obtained 2. 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 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. It may also have acquired genes from a species of archaea by horizontal gene transfer.


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 desulforufis and has not been diluted by surface water. Billions of years ago, some of the first bacteria on the planet may have thrived in similar conditions.

Candidatus Desulforudis audaxviator MPC – Taxonomy Result

The newly discovered microbes could shed light into the origins of life on Earth. The genome contains an unusual transposon and possesses many sites of insertion.

Its complete intolerance of oxygen suggests long-term isolation. The hydrocarbons in that environment do not come from living organisms. The source of the hydrogen needed for their respiration comes from the decomposition of water by radioactive decay of uraniumthoriumand potassium. The radiation allows for the production of sulphur compounds that these bacteria can use as a high-energy source of food.

The physiology that enables it to live audaxviaator these extreme conditions is a tribute to its unusually large genome, consisting of genes instead of the of czndidatus peers.
