研究了木质纤维生物质在高剪切环境中的酶促水解。在产生类似于双螺杆挤出机的剪切流动的扭矩流变仪中混合的样品中，纤维素到葡萄糖的转化率大于未混合的样品。此外，混合和酶解有协同效应；混合提高了纤维素的转化率，而增加的转化率促进了混合。这种协同作用似乎部分是由于颗粒尺寸的减小，当在强烈混合过程中发生水解时，这一点更加明显。(C)2010爱思唯尔有限公司。保留所有权利。
Enzymatic hydrolysis of lignocellulosic biomass in a high shear environment was examined. The conversion of cellulose to glucose in samples mixed in a torque rheometer producing shear flows similar to those found in twin screw extruders was greater than that of unmixed samples. In addition, there is a synergistic effect of mixing and enzymatic hydrolysis; mixing increases the rate of cellulose conversion while the increased conversion facilitates mixing. The synergy appears to result in part from particle size reduction, which is more significant when hydrolysis occurs during intense mixing. (C) 2010 Elsevier Ltd. All rights reserved.
