Human and animal gut is a nutrient rich environment, which is composed of a large number of complex microorganisms, including a large number of probiotics. Bifidobacteria, an important part of probiotics, is the dominant flora of human intestinal development in the early stage, and colonizes in the colon. Studies have shown that Bifidobacterium can promote intestinal proliferation, therefore, it is necessary to study the mechanism of proliferation promotion from the molecular level.
