Lignocellulosic materials are regarded as an alternative energy source for bioethanol production to reduce our reliance on fossil fuels. Pretreatment is important for improving the enzymatic digestibility and fermentation yield. In this study, barley straw was pretreated by using NaOH, to produce bioethanol. And by using RSM(Response urface Methodology), the optimum conditions of pretreatment was investigated. The independent variables for pretreatment were selected as pretreatment temperature, pretreatment time and NaOH concentration. The determined optimum condition is pretreatment temperature ; 129.02°C, pretreatment time ; 3.23h, NaOH concentration ; 12.58% (w/w, NaOH/Biomass). The results are as follow : Delignification ; 71.50%, Glucose concentration ; 31.61g/L, Ethanol concentration : 15.36g/L. This results may provide useful information with regard to the development of more economic and efficient bioethanol production.
