Lactobacillus johnsonii

Lactobacillus johnsonii is a Gram-positive, rod-shaped lactic acid bacterium, formerly grouped within the Lactobacillus acidophilus complex, supplied by Nustras as a freeze-dried probiotic culture powder. The culture is grown by controlled fermentation, concentrated, freeze-dried with a protective carrier and milled to a free-flowing powder at the stated viable count.

It is formulated into capsules, tablets, sachets and chewables, multi-strain probiotic blends, fermented dairy products, infant nutrition where permitted, and animal-feed and pet supplements. Several viable-count grades are available.

The material is a cream to light-beige powder with a faint fermented odour. Viable count is standardised to specification, with an overage for loss during shelf life, and confirmed by plate count; strain identity is confirmed by DNA-based methods, and moisture and water activity are reported. Absence of specified pathogens, heavy-metal and microbial limits are supplied to specification and confirmed on each lot's certificate of analysis. Cold storage is recommended.

Nustras supplies Lactobacillus johnsonii in bulk commercial quantities, in sealed moisture-barrier packaging within fibre drums, to manufacturers and formulators internationally, with a certificate of analysis, specification sheet and country-of-origin documentation on every lot. Lactobacillus johnsonii is an accepted probiotic species in major supplement and food markets; buyers confirm the strain, viable count and claim for their application.
