The name Methanocorpusculum has Latin roots. It means bodies that produce methane.[3]
Description and metabolism
The cells of these archaea are small, irregular, and coccoid in shape. They stain Gram-negative and are not very motile. They reduce carbon dioxide to methane using hydrogen, but they can also use formate or secondary alcohols. They cannot use acetate or methylamines. They grow fastest at temperatures of 30–40°C.[3]
