Research Progress on Pretreatment of Crop Straw with White Rot Fungi
Crop straw is rich in resources,which is a low-cost and renewable roughage source for ruminants.However,the high content of lignocellulose in straw when feeding animals limits the function of rumen micro-organisms in ruminants,so it cannot be effectively used.Its nutritional value has not been developed due to a short of ideal treatment method in practice.White rot fungus pretreatment is considered to be one of the meth-ods that can effectively improve the nutritional value of crop straw.The fungi can grow on the lack of nutrition straw and decompose lignocellulose into small molecular compounds,such as saccharides,that can be digested by ruminants by secreting one or more lignin degrading enzymes and free radicals.In this paper,the application status and treatment methods of crop straw as feedstuff were discussed,and the mechanism and influencing fac-tors of white rot fungi in the treatment of lignocellulose,as well as their application in vivo and in vitro were re-viewed,which provided a theoretical reference for improving the nutritional value of crop straw.[Chinese Journal of Animal Nutrition,2024,36(8):4823-4834]
