Methanospirillaceae is a family of microbes within the order Methanomicrobiales. ^[2]

This family contains only one genus, Methanospirillum. All its species are methanogenic archaea. The cells are bar-shaped and can form long filaments. Most produce energy via the reduction of carbon dioxide with hydrogen, but some species can also use formate as a substrate. They are Gram-negative and move using flagella on the sides of the cells. They are strictly anaerobic, and found in wetland soil and anaerobic stages of water treatment systems. ^[3]
