Biotechnology Letters Aims and scope Submit manuscript

Summary

The study shows that the yeastSaccharomyces cerevisiae ATCC 36859 can be successfully used for the production of fructose syrup from glucose-fructose mixtures or from Jerusalem artichoke juice by the conversion of glucose to ethanol. During these processes fructose concentration was unchanged.

Ethanol yield (YP/S), based on glucose consumed in Jerusalem artichoke juice, and ethanol concentration were 0.428 g/g and 1.7% (w/v) respectively. When the juice was supplemented with glucose higher ethanol concentrations were attained but with lower ethanol yields.
