Because of high contents of cellulose and hemicellulose, barley straw seems to be a potential lignocellulosic biomass for production of bioethanol. However, lignocellulose such as barley straw is difficult to hydrolyze using only cellulolytic enzymes due to its recalcitrant and heterogeneous structure. Barley straw is considered to account for the largest portion of available biomass and most of barley straw is wasted following harvesting in Korea. Ethanosolv applied organosolv pretreatment is more convenient method than other pretreatment. To provide milder ethanosolv condition and enhance the enzymatic saccharification, metal salts as a catalyst were employed in ethanosolv. Barley straw was soaked in aqueous ethanol solution (50 wt% ethanol, 1 wt% H2SO4) with 0.2~25mmol/L metal salt (FeSO4, Fe2(SO4)3, FeCl3, AlCl3, Al2(SO4)3, MgSO4). After soaking, the impregnated barley straw is heated at 170oC for 1hr.
