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.

Just the fact that life can survive on nuclear energy is pretty incredible. Reach Douglas Main at dmain techmedianetwork. The bacterium performs chemotaxis along chemical gradients, and takes up nutrients it needs.

The radiation allows for the production of sulphur compounds that these bacteria can use as a high-energy source of food. Nonetheless, a nitrogenase is present in the genome… D. Certain genes in the D. Its complete intolerance of oxygen suggests long-term isolation.
