木质纤维素生物质的有效和高效分解仍然是其用作可再生运输燃料的原料的主要障碍。需要更详细地了解生物质浆料在转化过程中的材料特性，以设计具有成本效益的转化工艺。用稀酸预处理的玉米秸秆在初始不溶性固体含量为20质量%的情况下进行一系列酶糖化实验，在此期间测量颗粒固体的浓度和浆料的流变性质屈服应力（λ（y））。糖化的秸秆糖化到pH4（lambda（y））的程度，
Effective and efficient breakdown of ligno-cellulosic biomass remains a primary barrier for its use as a feedstock for renewable transportation fuels. A more detailed understanding of the material properties of biomass slurries during conversion is needed to design cost-effective conversion processes. A series of enzymatic saccharification experiments were performed with dilute acid pretreated corn stover at initial insoluble solids loadings of 20% by mass, during which the conventration of particulate solids and the rheological property yield stress (lambda(y)) of the slurries were measure. The saccharified stover liquefies to the point of being pourable (lambda(y)
