Bacteria belonging to the genus Defluviitoga demonstrate a fermentative metabolism 3 2. The sole species of the genus can utilize a large variety of carbohydrates, as well as a number of complex polysaccharides such as chitin and cellulose 3 2. Proteins and fatty acids are not utilized 3. Growth occurs under anaerobic conditions, however 0.5% (v/v) O2 can be tolerated 3. Alternative terminal electron acceptors include thiosulfate and sulfur 3. Cells of Defluviitoga may occur singly, in pairs, or in long chains in pure culture 3. The in situ physiology of the genus in activated sludge has not been determind.
