Onstott}, title = {Environmental genomics reveals a single-species ecosystem deep within earth}, abstract = {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.}, year = {2008}, journal = {Science}, volume = {322}, number = {5899}, pages = {275-278}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-53749096964\&doi=10.1126\%2fscience.1155495\&partnerID=40\&md5=3fbef8f7ec55360565cee6b1653ba106}, doi = {10.1126/science.1155495}, }
