| description | Jerusalem artichoke (JA) is a low-requirement crop, which does not interfere
with food chain, and is a promising carbon source for industrial
fermentation. Microbial conversion of such a renewable raw material to useful
products, such as ethanol, is an important objective in industrial
biotechnology. In this study, ethanol was efficiently produced from the
hydrolyzates of JA obtained at different pH values (pH 2.5, pH 3.0 and pH
3.5), temperature (120, 130, 132 and 134°C) and hold time (30 and 60 min) by
Saccharomyces cerevisiae. The efficient degradation of JA by HCl under
certain experimental conditions was confirmed by thin-layer chromatography.
Ethanol concentration of 7.52% (w/w), which corresponds to 93.89 % of the
theoretical yield is achieved by ethanol fermentation of JA hydrolyzate
obtained at pH 2.5. [Projekat Ministarstva nauke Republike Srbije, br.
