Abstract

This paper describes the differences between the efficiency of enzymatic hydrolysis of selected lignocellulosic materials after pretreatment by cyclic freezing and thawing. It also discusses the analysis of the positive effect of alkaline conditions on pretreatment. The selected materials were Populus alba L., wheat straw from Triticum aestivum L. and Cannabis sativa. Three pretreatment methods were used to compare the efficiency of enzymatic decomposition of cellulose and cellulose accessibility. The best results show the wheat straw pre-treated at -20°C in the freezer with NaOH addition with a concentration of monosaccharides of 56.6 g.l-1 compared to initial hydrolysed material with a concentration of monosaccharides of 24.4 g.l-1. The results show better digestibility of grass compared to wood dendromass

通过冷冻预处理提高木质纤维素材料的酶水解效率

本文介绍了某些木质纤维素材料在经过循环冷冻和解冻预处理后，酶水解效率之间的差异。本文还讨论了碱性条件对预处理的积极影响分析。所选材料为白杨、小麦秸秆和大麻。采用了三种预处理方法来比较纤维素的酶分解效率和纤维素的可及性。最佳结果显示，在-20°C的冷冻室中添加NaOH预处理的小麦秸秆单糖浓度为56.6 g.l-1，而初始水解材料的单糖浓度为24.4 g.l-1。结果表明，草的消化率优于木质碎屑
