Abstract
The present invention concerns a process for the production of an aqueous mixture comprising isopropanol, n-butanol and ethanol, comprising a step in which an aqueous solution containing C5 and/or C6 sugars and acetate is fermented under strict anaerobic conditions in the presence of a fermenting microorganism of the genusand in which said aqueous solution has an acetate concentration in the range 0.5 to 10 g/L and a ratio by weight of (acetate)/(sum of C5 and/or C6 sugars) in the range 0.005 to 0.35 g/g.
