Barley straw is a lignocellulosic biomass that is a renewable organic substance and alternative source of energy. In this study, barley straw was converted to ethanol by Saccharomyces cerevisiae following dilute acid pretreatment. barley straw was treated at various sulfuric acid concentrations and reaction temperatures and times. Barely straw Optimize pretreated condition was in 1% dilute acid at 158℃ for between 12min. The pretreated samples were subjected to enzymatic digestibility test by using commercial enzymes. Following enzyme hydrolysis, Saccharomyces cerevisiae was inoculated for ethanol production. The structural change of barley straw after pretreatment and enzyme hydrolysis was examined by SEM and XRD. The results were analyzed to assess the overall effectiveness of the pretreatment.
