The invention discloses a fermentation medium for improving infiltration resistance and culture density of bifidobacterium adolescentis and application of the fermentation medium. The special fermentation medium for the bifidobacterium adolescentis contains isomaltooligosacharide and uracil. The fermentation culture medium is used for fermenting and culturing the bifidobacterium adolescentis, so that the bifidobacterium adolescentis with strong infiltration resistance can be obtained, and the fermentation culture medium can effectively promote the reproductive capacity of the bifidobacterium adolescentis, so that the bifidobacterium adolescentis can propagate a larger number of bacterial colonies in unit area/volume; the culture density of the bifidobacterium adolescentis is greatly improved, so that the industrial production value of the bifidobacterium adolescentis is improved.
