Biological methanation was assessed at 55 and 65 °C with mixed culture. The efficiency were better at 65 °C than 55 °C. Methane content of ca. 90% was achieved at productivity of 0.45 L CH4/L reactor/day. Reseeding of the process is required as when inoculum ages, efficiencies decrease. Methanothermobacter species dominate in the ex-situ methanation community.
