Complete Genome Sequence of Methanobacterium sp. DP, a Hydrogenotrophic and Thermophilic Methanogen

Wind and solar energy are playing an increasingly vital role in power generation. Due to their own nature, their storage cannot be scheduled. Energy storage is becoming a priority for balancing renewable energy production and energy demand. In that regard, Power to Gas (P2G) plays a key role in meeting future energy needs by designing efficient and flexible energy storage. Alternatively, methanogens aid the process of combining surplus hydrogen with a carbonaceous stream to convert it to methane, making it fully acceptable for direct grid injection. In this study, a novel, strictly anaerobic, thermophilic, hydrogenotrophic methanogen, Methanobacterium thermaggregans strain DP, was isolated from a lab scale anaerobic digester fed with cigarette waste. The high-performance methane-producing strain was isolated in a minimal medium with hydrogen and carbon dioxide as substrates.
