Desulforudis audaxviator

Audaxviator is a sulfate reducing chemoautotroph, capable of fixing nitrogen and carbon. The hydrogen peroxide reacts with the environmental sulfide to form sulfate.

The bacteria can then use the sulfate for dissimulatory sulfate reduction, returning the compound to sulfide. Electrons from the hydrogen left over from the splitting of water are used audaxviagor the cell to reduce sulfate.

Ammonia is thought to be at a high enough concentration to provide a sufficient source of nitrogen.

The bacterium has transporters for both sugars and amino acids, which can be used a carbon source if they are available in the environment. Formate and CO may also be used as a carbon source. The bacterium performs chemotaxis along chemical gradients, and takes up nutrients it needs.

This may include taking up nutrients recycled from dead cells. From MicrobeWiki, the student-edited microbiology resource.
