Factors affecting alcohol fermentation of wood acid hydrolysate

The inhibitory effects of ethanol and furfural on the growth of Saccharomyces cerevisiae and ethanol production, at different glucose and furfural concentrations, were examined. The data collected during the fermentation of glucose with no furfural present in the medium fitted the model system proposed by Aiba et al. Furfural disappeared rapidly from the medium at the early stages of fermentation, followed by a constant rate which continued throughout the experiment. The initial furfural concentration of 3 g/L decreased the cell multiplication and the fermentation rate to 59 and 33%, respectively. The furfural concentration in this medium reached 60% of its initial value after 27.5 h.
