Description:
Geochemical, microbiological, and molecular analyses of alkaline saline groundwater at 2.8 kilometers depth in Archaean metabasalt revealed a microbial biome dominated by a single phylotype affiliated with thermophilic sulfate reducers belonging to Firmicutes. These sulfate reducers were sustained by geologically produced sulfate and hydrogen at concentrations sufficient to maintain activities for millions of years with no apparent reliance on photosynthetically derived substrates.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lin, Li-Hung -- Wang, Pei-Ling -- Rumble, Douglas -- Lippmann-Pipke, Johanna -- Boice, Erik -- Pratt, Lisa M -- Sherwood Lollar, Barbara -- Brodie, Eoin L -- Hazen, Terry C -- Andersen, Gary L -- DeSantis, Todd Z -- Moser, Duane P -- Kershaw, Dave -- Onstott, T C -- New York, N.Y. -- Science. 2006 Oct 20;314(5798):479-82.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Geosciences, Princeton University, Princeton, NJ, USA. lhlin@ntu.edu.tw〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17053150" target="_blank"〉PubMed〈/a〉
