摘　　要：优质饲料资源不足严重制约着我国畜牧业发展。纤维是自然界中分布最广且数量最多的可再生资源,因其结构复杂且许多动物缺乏相应降解酶而难以被利用。然而,部分微生物可通过分泌相应纤维降解酶系,将纤维降解为低聚糖或被自身利用产生益生物质。因此,纤维高效降解微生物的选育,对新型饲料资源开发和纤维饲料利用具有重要的意义。本文针对近年来国内外纤维高效降解微生物的筛选、改造和应用进行综述,旨在为我国优质微生物种质资源的挖掘和新型饲料资源的开发提供新思路。The shortage of high-quality feed resources is seriously restrictings the development of our country’s animal husbandry industry.Fiber is the most widely distributed and abundant renewable resource in nature,which is difficult to be utilized due to its complex structure and the lack of corresponding degradation enzymes in many animals.However,some microorganisms can degrade fiber into oligosaccharides or use it themselves to produce beneficial biomass by secreting the appropriate fiber-degrading enzyme system.Therefore,the selec-tion and breeding of high-efficiency fiber degrading microorganisms is of great significance for the development of new feed resources and the utilization of fiber feed.In this paper,the screening,modification and applica-tion of fiber degrading microorganisms at home and abroad in recent years were reviewed,aiming at providing new ideas for the mining of high-quality microbial germplasm resources and the development of new feed re-sources in China.
