Baccillus Subtilis “natto”

Bacillus subtilis "natto" (Bacillus subtilis var. natto) is a Gram-positive, spore-forming bacterium, the strain traditionally used to ferment soybeans into the Japanese food natto, supplied by Nustras as a dried spore powder for the probiotic and supplement sector. It produces the serine protease nattokinase during fermentation, and its endospores tolerate heat, drying and acid.

It is formulated into probiotic supplements in capsule, tablet, sachet and powder form, multi-strain probiotic blends, functional foods, beverages and fermented-food starter cultures, and animal-feed and pet-food products as a direct-fed microbial.

The material is a white to light yellow free-flowing powder on a food-grade carrier. Viable count (CFU per gram) is standardised to specification and determined by plate count; strain identity is confirmed by microbiological and molecular (16S rRNA) identification, and loss on drying, heavy-metal, contaminant-organism and microbial limits are supplied to specification and confirmed on each lot's certificate of analysis.

Nustras supplies Bacillus subtilis "natto" in bulk commercial quantities, in sealed packaging and fibre drums, to manufacturers and formulators internationally, with a certificate of analysis, specification sheet and country-of-origin documentation on every lot. Bacillus subtilis is an accepted probiotic and feed-microorganism ingredient in major markets, with permitted strains differing by jurisdiction; buyers confirm the permitted strain, level and claim for their application.
