Most species exhibit asluggish motilityand a peritrichous arrangement of 2–6 flagella (retarded peritrichous flagellation). Cells arerod shapedand occur in various arrangements that vary by species. Many of theThermoanaerobacterspecies formpleomorphic cellsduring the late exponential and stationary growth phases assembling through nonsymmetric cell division chains of alternating rod‐shaped and coccoid cells. Other types of pleomorphic rods are formed, presumably through weakening of the cell wall by lysozyme‐like enzymes that are the remnants of the sporulation process (Figure1). Growth temperature optima range from 55–75 °C, withgrowth ranges of 35–78°Cand atemperature span over 35°C. The pH for growth ranges frompH25C4.0–9.9, with a pH optimum of 5.8–8.5. Several species also exhibit a wide pH optimum of about 3 units without a sharp peak. All species are able to groworganoheterotrophicallyusing various fermentation pathways including the homoacetogenic or Wood–Ljungdahl pathway, or using inorganic electron acceptors (e.g.,Thermoanaerobacter sulfuriphilususing S0as an electron acceptor and lactate as an electron donor and carbon source). SomeThermoanaerobacterstrains are also able to growchemolithoheterotrophically by coupling H2oxidationto growth (Fardeau et al., 1994). Furthermore, others arefacultative chemolithoautotrophs, growing with H2+ CO2(such asThermoanaerobacter kivui) or Fe(III) + H2+ CO2(such asThermoanaerobacter siderophilus). Generally, typical fermentation products from hexoses are ethanol, acetate, lactate, H2, and CO2.DNA G+C content(mol%): 30–39.Type species:Thermoanaerobacter ethanolicusWiegel and Ljungdahl 1982, 384VP(Effective publication: Wiegel and Ljungdahl 1981, 348.).
