We found that Thermosipho africanus was able to ferment D-glucose, D-ribose, maltose, and starch, while D-galactose, fructose, and sucrose were utilized poorly. Acetate, H2, and CO2, as well as small amounts of ethanol and lactate, were end products of glucose metabolism in this organism. The presence of thiosulfate as an electron acceptor greatly improved growth and increased acetate production from the sugars. The genus Thermosipho is the only genus in the order Thermotogales that has been described as a non-carbohydrate fermenter. We propose that the description of the genus Thermosipho be emended because the only species in this genus, T. africanus, is a carbohydrate fermenter that is able to utilize thiosulfate as an electron acceptor.
