Pretreatment of reed by wet oxidation and subsequent utilization of the pretreated fibers for ethanol production.

摘要: Common reed (Phragmites australis) is often recognized as a promising source of renewable energy. However, it among the least characterized crops from bioethanol perspective. Although one third dry matter cellulose, without pretreatment, resists enzymatic hydrolysis like lignocelluloses usually do. In present study, wet oxidation was investigated pretreatment method to enhance digestibility cellulose soluble sugars and thus improve convertibility ethanol. The most effective treatment increased by cellulases more than three times compared untreated control. During this oxidation, 51.7% hemicellulose 58.3% lignin were solubilized, whereas 87.1% remained in solids. After pretreated fibers same treatment, conversion glucose 82.4%. Simultaneous saccharification fermentation solids resulted final ethanol concentration high 8.7 g/L, yielding 73% theoretical.
