摘要
木质纤维素是秸秆细胞壁的主要成分,是一种可循环利用的物质资源,在饲料领域具有很大的利用价值,主要包含纤维素、半纤维素和木质素。其中木质素是位于植物中的一种芳香族聚合物,主要存在于农作物秸秆中,具有抗菌、抗氧化、抗糖尿病、抗炎等多种生物学功能,但因其结构复杂、水溶性低、难降解等因素难以被充分利用,造成了秸秆资源的浪费和环境污染。本文综述了秸秆中木质素的化学组成、主要降解方法及降解菌在畜牧生产中应用的研究进展,旨在为木质素降解菌在动物生产中绿色、安全应用提供参考依据。
Lignocellulose,the main component of straw cell wall,is a recyclable material resource with significant utilization protential in the feed industry.It mainly consists of cellulose,hemicellulose,and lignin,among which,lignin is an aromatic polymer compound found in plants,primarily present in crop straws,and exhibits various biological functions such as antibacterial,antioxidant,antidiabetic,and antiinflammatory activities.However,due to its complex structure,low water solubility,and resisrance to degradation,lignin is difficult to be fully utilized,leading to the waste of straw resources and environmental pollution.This paper reviewed the chemical composition of lignin,main lignin degradation methods,and research progress of lignin-degrading bacteria in animal production,aiming to provide a reference basis for the green and safe application of lignin-degrading bacteria in livestock production.
