Description:
DNA from low-biodiversity fracture water collected at 2.8-kilometer depth in a South African gold mine was sequenced and assembled into a single, complete genome. This bacterium, Candidatus Desulforudis audaxviator, composes 〉99.9% of the microorganisms inhabiting the fluid phase of this particular fracture. Its genome indicates a motile, sporulating, sulfate-reducing, chemoautotrophic thermophile that can fix its own nitrogen and carbon by using machinery shared with archaea. Candidatus Desulforudis audaxviator is capable of an independent life-style well suited to long-term isolation from the photosphere deep within Earth's crust and offers an example of a natural ecosystem that appears to have its biological component entirely encoded within a single genome.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chivian, Dylan -- Brodie, Eoin L -- Alm, Eric J -- Culley, David E -- Dehal, Paramvir S -- DeSantis, Todd Z -- Gihring, Thomas M -- Lapidus, Alla -- Lin, Li-Hung -- Lowry, Stephen R -- Moser, Duane P -- Richardson, Paul M -- Southam, Gordon -- Wanger, Greg -- Pratt, Lisa M -- Andersen, Gary L -- Hazen, Terry C -- Brockman, Fred J -- Arkin, Adam P -- Onstott, Tullis C -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2008 Oct 10;322(5899):275-8. doi: 10.1126/science.1155495.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Physical Biosciences Division, Lawrence Berkeley National Laboratory, Berkeley, CA 94720, USA.
