Research Progress on Biodegradation of Lignin in Process of Straw Feed
Straw resources are abundant in China,but the proportion of straw used as feed is low.Straw ligno-cellulose,especially the lignin in it'is difficult to be digested and utilized by animals,which is one of the key constraints affecting the process of straw as feed.Improving the nutritional value of straw by biodegrading lig-nin is a green,economical,and production-ready way to promote straw as feed.In this paper,the chemical composition and function of straw lignin,lignin-degrading microorganisms and related degrading enzymes,the biofermentation and degradation of lignin and its application in animal breeding were reviewed,in order to pro-vide a reference for the production of straw as feed.[Chinese Journal of Animal Nutrition,2024,36(8):4782-4794]
