Methanobacterium is a genus of Archaea belonging to the Methanobacteriaceae family.
Methanobacteria can be employed in the anaerobic digestion (AD) process to convert biomass into energy.
The utilization of microbial communities in anaerobic digestion (AD) allows for the clean energy conversion of organic wastes by lowering the wastes' chemical and biological oxygen demands.
Methanobacterium are non-moving and oxygen-free.
Some species of this genus can reduce methane with formate, whereas others can only survive by reducing carbon dioxide with hydrogen.
They are common in some hot, low-oxygen habitats, such as hot springs, anaerobic digesters, and associated effluents.
