Bifidobacterium infantis

Bifidobacterium infantis, now classified as Bifidobacterium longum subsp. infantis, is a Gram-positive anaerobic bacterium of the genus Bifidobacterium that is naturally present in the intestinal microbiota of breastfed infants. The species is notable for its ability to metabolise human milk oligosaccharides. Nustras supplies Bifidobacterium infantis as a freeze-dried bacterial culture in powder form, used as a probiotic ingredient.

The culture is formulated into probiotic supplements in capsule, sachet, drop and tablet form, into multi-strain blends and premixes, into infant and follow-on nutrition products where permitted, and into functional foods and beverages.

The material is a freeze-dried culture on a food-grade carrier such as maltodextrin, supplied as a free-flowing off-white powder. Viable count is standardised to specification and determined by plate count under anaerobic conditions, with identity confirmed by microscopy and molecular identification; moisture and heavy-metal and microbial limits are supplied to specification and confirmed on each lot's certificate of analysis.

Nustras supplies Bifidobacterium infantis in bulk commercial quantities, in sealed moisture-barrier packaging within fibre drums or cartons, to manufacturers and formulators internationally, with a certificate of analysis, specification sheet and country-of-origin documentation on every lot. Bifidobacterium longum subsp. infantis is an accepted probiotic species in major markets; buyers confirm the strain, permitted use and labelling for their application.
