Fed‐batch production of concentrated fructose syrup and ethanol using Saccharomyces cerevisiae ATCC 36859

Abstract

AbstractA fed‐batch process is used for the production of concentrated pure fructose syrup and ethanol from various glucose/fructose mixtures by S. cerevisiae ATCC 36859. Applying this technique, glucose‐free fructose syrups with over 250 g/l of this sugar were obtained using High Fructose Corn Syrup and hydrolyzed Jerusalem artichoke juice. By encouraging ethanol evaporation from the reactor and condensing it, a separate ethanol product with a concentration of up to 350 g/l was also produced. The rates of glucose consumption and ethanol production were higher than in classical batch ethanol fermentation processes.
