title: [Effects of terminal products on hydrogen production by ethanol hydrogen-producing microflora].
abstract: The effects of terminal products on hydrogen production were conducted in continuously stirred tank reactor (CSTR) by the acclimated ethanol hydrogen-producing bacteria. Glucose was added as carbon source and different ambient pH was carried out by buffer solution. High ethanol production was simultaneously achieved with high hydrogen production. The addition of 40 mol/L ethanol or acetic acid can result in the reduction of hydrogen production, the former was 34% and the latter was 84.3%. The ethanol fermentation formation for mixed microflora was attributed to the natural selection.
