. The bacteria produce ethanol and acetic acid as fermentation products, but do not produce lactic acid. The growth range of ''T. ethanolicus'' is 40-80°C and pH 5.5-8.5, with the optimum growth temperature around 65°C. The species was originally placed in its own new genus of ''Thermobacteroides'' in 1981. In 1993, based on further study, the species was moved into the genus ''

Thermoanaerobacter ''Thermoanaerobacter'' is a genus in the phylum Bacillota (Bacteria). Members of this genus are thermophilic and anaerobic, several of them were previously described as ''Clostridium'' species and members of the now obsolete genera ''Acetogenium ...
