Abstract


Abstract: The aim of this study was the production of bioethanol from wood by steam-explosion pretreatment, enzymatic hydrolysis and fermentation of glucose. Separate hydrolysis and fermentation was applied for cellulose hydrolysis, followed by fermentation with S. cerevisiae. Using H2SO4 – impregnated of wood chips in steam pretreatment resulted in the high ethanol concentration. In this work, the steam-explosion pretreatment conditions for wood chips were optimized to obtain higher ethanol yield. A commercial enzymes mixture was used for enzymatic hydrolysis of wood.
