Abstract

An autotrophic moderately alkaliphilic and thermophilic nonmotile rod-shaped methanogen was isolated from a biogas plant. The isolate grows only on H2+CO2 and requires yeast extract. Growth optimum is at 60°C with a generation time of 4 h. In the absence of substrates complete lysis occurs. The pH range for growth is 7.5–8.5. Growth was also observed at pH values above 9.0. The DNA base composition is 38.8 mol% G+C. According to its physiological properties the nameMethanobacterium thermoalcaliphilum is proposed.
