摘要
酵母培养物(YC)是将酵母菌活化后,通过液体发酵接种于底物中,并经过高密度固态发酵制成的微生态制品。YC主要由酵母菌体、酵母细胞壁、酵母细胞内容物、发酵的代谢产物及变性培养基组成,其含有丰富的寡糖、小肽、氨基酸、酶类、维生素、核酸等物质。YC具有诱食、提高机体免疫力、吸附病原菌及毒素、维持肠道菌群平衡、促进生长等功效,是一种优质的功能性饲料原料。但由于菌种、底物及工艺等不同,不同来源酵母培养物营养功能与应用效果差异较大。文章综述了酵母培养物的营养特性、功能机理及其在动物生产中的应用研究进展,以期为酵母培养物产品的开发及其在动物养殖生产中的应用提供参考。
Yeast culture(YC)is a microbial product prepared by activating yeast strains,inoculating them into substrates via liquid fermentation,and processing through high-density solid-state fermentation.YC primarily consists of yeast cells,yeast cell walls,intracellular components,fermented metabolites,and modified culture medium.It is rich in oligosaccharides,small peptides,amino acids,enzymes,vitamins,nucleic acids,and other bioactive compounds.YC has the functions of improving palatability,enhancing immune function,adsorbing pathogenic bacteria and toxins,maintaining intestinal microbiota balance,and promoting growth,making it a high-quality functional feed ingredient.However,due to variations in microbial strains,substrates,and processing techniques,the nutritional efficacy and application outcomes of YC from different sources can vary significantly.This article reviews the nutritional properties,functional mechanisms,and recent advances in the application of YC in animal production systems,aiming to provide references for optimizing YC product development and its practical utilization in animal production.
