Bifidobacterium longum cbt bg7 strain for promotion of growth and nutraceutical composition for promotion of growth containing the same

Abstract

The present invention a Bifidobacterium longum CBT BG7 Bifidobacterium , which has an excellent growth promoting effect and was internationally deposited with the Korean Collection for Type Culture (KCTC) of the Korea Research Institute of Bioscience and Biotechnology under accession number KCTC 12200BP. The strain of the present invention has a beneficial effect of promoting growth by promoting the digestion of human milk oligosaccharides to enhance immunity together with physical strength.
