Generally,bio-ethanol production from lignocellulosic biomass
consists of three major steps,namely:(i) pretreatment,(ii) enzymatic
hydrolysis and (iii) fermentation.The first step,which
involves pretreatment has been discussed in the earlier section.The
second step is the enzymatic hydrolysis process.This step involves
conversion of cellulose into glucose,and hemicellulose into several
pentoses and hexoses .The glucose is finally fermented
into ethanol by selected microorganism.Note that the conversion
of cellulose and hemicellulose fractions of lignocellulosic
biomass such as rice straw and rice husk,can be achieved either by
simultaneous saccharification and fermentation (SSF) or separate
enzymatic hydrolysis and fermentation.Binod et al.provide
an overview on the potential technologies to produce ethanol from
rice straw.Chen and Qiu discussed their group’s recent research
advances in ethanol production technologies from rice straw that
are based on fractional conversion .

一般情况下,从木质纤维素生物质生成生物乙醇包括三个主要步骤,即：（一）预处理,（二）酶的水解及（三）发酵.第一个步骤涉及预处理,我们已在前面的章节中讨论过了.第二个步骤是酶的水解过程.该步骤包括将纤维素转化成葡萄糖,并将半纤维素转化为几种戊糖和己糖.葡萄糖最后由选定的微生物发酵而转化成乙醇.请注意,诸如稻草和稻壳等木素纤维素生物质的纤维素和半纤维素部分,其转化过程可以通过同时进行糖化和发酵（SSF）或单独的酶水解和发酵来实现.比诺德等提供了用稻草生产乙醇的可用技术的概述.陈和邱讨论了他们小组最近研究从稻草生产乙醇的技术在转化率方面所取得的进展.

通常，从木质纤维生物质中生产生物乙醇包含三个主要步骤，即：1. 预处理；2. 酶法水解；3. 发酵。涉及到预处理的第一步已在前面的章节讨论过了。第二步是酶法水解过程，这一步包含纤维转化为葡萄糖和半纤维素转化为几种戊糖和己糖。戊糖最终被选中的微生物发酵为乙醇。注意，木质纤维生物质中纤维素和半纤维素的转化，如稻秆和稻壳，既可以用同步糖化和发酵（SSF）的方法，也可以用分开的酶法水解和发酵的方法完成。B...
