在糖化前对麦秆进行三种不同的处理，即碱制浆、自然制浆和自水解，以研究它们对酶水解速率的影响。为了优化每种方法，改变了介质浓度、温度和时间等参数。与研究的其他研磨方法相比，将原材料预先研磨至 4 毫米的长度显示出最佳的成本价值比。在糖化之前，果肉可以以干燥形式储存，从而产生高产率的葡萄糖。此外还讨论了纸浆特性（即特性粘度、KLASON-木质素和半纤维素含量、结晶度、形态）与纤维素水解的关系。 (C) 2014 Elsevier Ltd. 保留所有权利。
Wheat straw was subjected to three different processes prior to saccharification, namely alkaline pulping, natural pulping and autohydrolysis, in order to study their effect on the rate of enzymatic hydrolysis. Parameters like medium concentration, temperature and time have been varied in order to optimize each method. Milling the raw material to a length of 4 mm beforehand showed the best cost-value-ratio compared to other grinding methods studied. Before saccharification the pulp can be stored in dried form, leading to a high yield of glucose. Furthermore the relation of pulp properties (i.e. intrinsic viscosity, KLASON-lignin and hemicelluloses content, crystallinity, morphology) to cellulose hydrolysis is discussed.
