Moderately thermophilic anaerobes with chemoorganotrophic metabolism 2 3 4. Members of the genus are fermenters of organic acids, proteins (amino acids and casamino acids) and peptides and a limited number of carbohydrates 2 3 4. The products of these fermentations are acetate, hydrogen and CO2 2 3 4. "Glucose and malate degradation are enhanced in co-culture with M. thermoautotrophus" 4. Cells grow as straight to slightly curved rods 2 3 4. No in situ data has been determined for the Genus.
