Beschreibung
Zusammenfassung:	A process for production of glucose having purity greater than 98% from pretreated cellulosic biomass comprising 50-95% cellulose, using thermo-chemical and enzymatic treatment, is disclosed. The process involves mild acid and/or alkali treatment of the pretreated cellulosic biomass for production of treated cellulosic biomass residue comprising polysaccharides containing greater than 98% glucose.The treatment results in high purity cellulose that is highly amenable to enzymatic hydrolysis and yields glucose having purity greater than 98%. The process also involves membrane separation of enzymes and oligosaccharides for recycling and separation of glucose to avoid product feedback inhibition. 本公开提供使用热-化学和酶促处理从包含50-95％纤维素的经预处理的纤维素生物质生产纯度大于98％的葡萄糖的方法。本公开的方法涉及经预处理的纤维素生物质的温和的酸和/或碱处理，用于生产包含含有大于98％葡萄糖的多糖的经处理的纤维素生物质残余物。处理导致高度适用于酶促水解的高纯度纤维素，并且产生纯度大于98％的葡萄糖。本公开的方法还涉及酶和寡糖的膜分离，用于葡萄糖的回收和分离，从而避免产物反馈抑制。
