  • 描述: 本研究係將兩類能源作物製造纖維酒精，如傳統農業廢棄物(蔗渣和玉米葉)與本土性潛力能源作物(象草、李氏禾和蘆葦)產生可醱酵糖濃度與乙醇產率之比較。研究顯示產生可醱酵糖濃度最高為玉米葉，濃度為9.23 mg/ml。除此之外，象草因乙醇產率微高，故產製乙醇濃度比其他四種原物料來的高，使用傳統之酵母菌每克原物料可得到0.044g 乙醇，乙醇轉化率約為14.19%。使用SEM觀察對稀酸加壓力鍋蒸煮下之固態物料，網狀結構有明顯裸露並且其上之孔徑隨水解時間增加而變大，此物理結構改變可能因處理下增加其可醱酵糖濃度。
    Fermentation sugar concentrations and ethanol yield related to two kinds of energy plants, traditional agriculture wastes (bagasse and corn leaves) and local candidate plants (Pennisetum purpureum、Leersia hexandra and Phragmites communis), were investigated for their use in ethanol production. In this study, the fermentation sugar highest concentrations 9.23mg/ml from corn leaves. In addition to ethanol concentrations in Pennisetum purpureum highest then others plants because it had slightly higher ethanol yield. Traditional yeast produced 0.044g ethanol/ g raw material , corresponding to 14.19% of theoretical ethanol yield.SEM results indicated that autoclave reactor with dilute acid pretreatment increased surface area and pore size. It is postulated that these physical changes enhance fermentation sugar concentrations in the dilute acid treated raw materials.
