A1 MAGOT, MICHEL A1 GARCIA, JEAN-LOUISYR 1996 T1 Emended Description of Thermosipho africanus as a Carbohydrate-Fermenting Species Using Thiosulfate as an Electron Acceptor JF International Journal of Systematic and Evolutionary Microbiology, VO 46 IS 1 SP 321 OP 323 DO https://doi.org/10.1099/00207713-46-1-321 PB Microbiology Society, SN 1466-5034, AB 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., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/00207713-46-1-321
