butyricum TISTR1032 for ethanol and ABE production, respectively. The ethanolic fermentation (by using
S. cerevisiae) of CP (67 g/L) in sterilized wastewater solution, yielded a bioproduct mixture having
a content consisting (beside other components) from 8.8 g/L of ethanol, but this ethanol concentration
was increased to 12.9 g/L with the replacement of the water by CWW. Fermentation of the saccharified
CP alone or with CWW with C. butyricum yielded a total ABE production of 9.65 g/L and 10.24 g/L,
respectively, but the ethanolic production was reduced from 9 g/L (93% of the solvent composition) to
1.64 g/L (16% solvent composition) by the addition of the CWW, with butanol as the major product
(53.2%; 2.5 g/L).
