'Caloramator', is a genus of bacteriae belonging to the Firmicutes. Straight to slightly curved rods or filaments (2–100 × 0.4–0.8 µm), which occur singly or pairs. Cells stain Gram-negative or Gram-positive but possess a Gram-positive cell-wall ultrastructure. May be motile or nonmotile. Endospores may or may not be produced and if present, are spherical and located terminally or subterminally and do not distend the sporangia. All species grow at thermophilic temperatures (growth temperature optimum between 50 and 68 °C). The metabolism is heterotrophic and saccharolytic and the end products from glucose fermentation are acetate, isobutyrate, isovalerate, valerate, lactate and ethanol. Unable to grow autotrophically or produce sulfur from thiosulfate.
