Outline
Human-Residential Bifidobacteria are important beneficial bacteria in the intestinal tract. The dominant species change with age and can be classified into infant-type Bifidobacteria and Adult-type Bifidobacteria. Recent studies have shown that infant-type Bifidobacteria have unique intestinal adhesion and colonization capabilities, can specifically metabolize human milk oligosaccharides (HMOs) and synthesize bioactive substances such as short-chain fatty acids (SCFAs), tryptophan derivatives, and secondary bile acids. It demonstrates unique probiotic effects in regulating host metabolism and safety. However, current research mainly focus on the functional domain, while there are still many bottlenecks in industrial technology research,which seriously limit its application scope and efficacy. In the future, in addition to continuing to study the functions and mechanisms of infant-type Bifidobacteria, research on processing technology should also be actively developed to break through the technical bottlenecks of commercial application of infant-type Bifidobacteria, enabling it to exert a greater role in maintaining human health and preventing diseases.
