Description

technical field

[0001] The invention relates to the technical field of microorganisms, in particular to a bifidobacterium and its active protein and its application. Further, the bifidobacteria can be prepared into selenium-enriched probiotics through selenium-enriched culture. Background technique

[0002] Probiotics are a class of microorganisms that can have beneficial effects on the host and are closely related to human health. Probiotics generally colonize the intestinal tract and reproductive system of the human body, and play an important role in maintaining the micro-ecological balance in the human body. Existing research results have shown that the stability of human microbiota is very important for maintaining human health. Aging, hypertension, diabetes and intestinal diseases are all related to human microbiota. The imbalance of microbiota in the human body will directly or indirectly lead to the occurrence of these diseases. Bifidobacterium is a common physiolo...
