Onstott1 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. http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=search&term=10376671 FEBS Lett. 1999 Jun 4;452(1-2):22-5 Minireview: Extremophiles and their adaptation to hot environments. Stetter KO. Water-containing terrestrial, subterranean and submarine high temperature areas harbor a variety of hyperthermophilic bacteria and archaea which are able to grow optimally above 80 degrees C. Hyperthermophiles are adapted to hot environments by their physiological and nutritional requirements. As a consequence, cell components like proteins, nucleic acids and membranes have to be stable and even function best at temperatures around 100 degrees C. The chemolithoautotrophic archaeon Pyrolobus fumarii is able to grow at 113 degrees C and, therefore, represents the upper temperature border of life. For the first time, (vegetative) cultures of Pyrolobus and Pyrodictium are able to survive autoclaving. -- ┌─────◆ＫＫＣＩＴＹ◆─────┐ ◢　◤ 听 KKBOX，动态歌词紧紧跟着你 │ bbs.kkcity.com.tw │ \^_^ / ★ http://www.kkbox.com.tw ★ └──《From:143.48.8.154 》──┘ 　 ◤ 唱片公司授权，音乐尽情下载 --
