英文摘要：

Genome sequencing of more than 80 thermophiles has pro- vided powerful databases for the preliminary determination of genes essential to thermal adaptation （Berka et al., 2003; Berezovsky and Shakhnovich, 2005; Andrews et al., 2010）. A laboratory strain of Thermoanaerobacter tengcongensis MB4 has been shown to grow at temperatures over the range 50℃ to 80℃, with an optimum of 75℃ （Xue et al., 2001） and its thermal adaptation mechanisms have been studied with the sequencing of its genome （Bao et al., 2002）. Using two- dimensional gel electrophoresis （2DE） and Matrix-Assisted Laser Desorption/Ionization Time of Flight （MALDI-TOF/ TOF） mass spectrometry, Wang et al.
