Methanothermobacter

Methanothermobacter is a genus of archaeans in the family Methanobacteriaceae.^[1] The species within this genus are thermophilic and grow best at temperatures between 55 °C and 65 °C. They are methanogens; they use carbon dioxide and hydrogen as substrates to produce methane for energy.^[2]
