Soybean hulls and soybean dregs are the byproducts of soybean proecessing and are rich incellulose and other polysaccharides. Cellulose and other polysaccharides are mainly composed ofglucose through glycosidic bonds to the polymer.Polysaccharides completely hydrolyzed toglucoseand other reducing sugars that may be prepared as bio-ethanol by fermentation, and bio-ethanol isa renewable green organicenergy. However, due to the strong hydrogen bond and the highly cryst-alline, cellulose is difficult to be deco...
