The Deferribacteraceae are a family of gram-negative bacteria which make energy by anaerobic respiration. Description Deferribacteraceae are rod-shaped, although the rods may be straight or bent. They are gram-negative. Deferribacteraceae perform anaerobic respiration using iron, manganese, or nitrate. They can also produce energy by fermentation. The type genus of the family is Deferribacter.
