Bifidobacterium longum

Bifidobacterium longum is a Gram-positive, anaerobic bacterium of the genus Bifidobacterium and one of the species most commonly found in the human intestinal microbiota from infancy onward. Nustras supplies it as a freeze-dried probiotic culture powder, produced by controlled fermentation and blended with a food-grade carrier, for the supplement, food and feed industries.

It is formulated into probiotic capsules, sachets, tablets, chewables and powder blends, alone or in multi-strain combinations, and into fermented dairy products, infant and follow-on formulas, functional foods and beverages designed to carry live cultures.

The material is a cream to off-white free-flowing powder. Viable count is determined by plate count on selective media and standardised to specification, with species identity confirmed by ribosomal RNA sequencing or PCR. Moisture, heavy-metal and microbial limits, including absence of specified pathogens, are supplied to specification and confirmed on each lot’s certificate of analysis.

Nustras supplies Bifidobacterium longum in bulk commercial quantities, in sealed moisture-barrier bags inside fibre drums, shipped under temperature control, to manufacturers and formulators internationally, with a certificate of analysis, specification sheet and country-of-origin documentation on every lot. Bifidobacterium longum is an accepted probiotic species in major supplement and food markets; buyers confirm the strain, permitted level and claim for their application.
