Abstract

Pretreatment serves as an important step in maximizing the efficient utilization of woody biomass feedstock. This study focused on enhancing the component and structural properties of apple wood to optimize the utilization of apple wood resources effectively. This study presents the optimization of, the apple wood pretreatment system, combining bioenzyme and hydrothermal treatments. This study aimed to investigate the effect of different bioenzyme pretreatment conditions on the components and structural properties of apple wood extract and to analyze the feasibility of enzyme solution reuse. Fourier transform infrared spectroscopy analysis revealed an increase in cellulose content in the wood flour following enzyme treatment. Concurrently, changes in characteristic peaks indicated an increased hemicellulose content and a reduction in lignin content after the pretreatment, correlating with fraction analysis results. Scanning electron microscopy illustrated that the dense structure of the fiber surface was disrupted after treatment. Notably, the results indicated that the recovered biocomposite enzymes exhibited excellent activity, suggesting their potential for reuse.

水热酶预处理对苹果枝条结构和特性的影响

预处理是最大限度地有效利用木质生物质原料的重要步骤。本研究的重点是提高苹果木材的成分和结构特性，从而有效优化苹果木材资源的利用。本研究介绍了结合生物酶和水热处理的苹果木材预处理系统优化。本研究旨在探讨不同生物酶预处理条件对苹果木材提取物成分和结构特性的影响，并分析酶液重复使用的可行性。傅立叶变换红外光谱分析显示，经过酶处理后，木粉中的纤维素含量有所增加。同时，特征峰的变化表明预处理后半纤维素含量增加，木质素含量减少，这与馏分分析结果相关。扫描电子显微镜显示，纤维表面的致密结构在处理后被破坏。值得注意的是，结果表明回收的生物复合酶具有极佳的活性，这表明它们具有再利用的潜力。
