STRAIN-IDENTIFIED CULTURE
Bacillus subtilis D165
Bacillus subtilis D165 is supplied as a strain-identified freeze-dried culture for B2B probiotic blends. The purchasing definition is the strain designation and the delivered potency rather than the species name alone.

Buyer Decision Guide
Probiotics are specified by strain, potency at delivery and enumeration method. Confirm the strain designation, the CFU basis (per gram or per dose) and the overage required to hold potency through your shelf life and packing format.
- Confirm the strain designation, not only the species
- Check the CFU basis and enumeration method
- Review water activity and viability data
- Confirm cold-chain and packing requirements
How This Grade Differs
D165 is a specific strain and is not interchangeable with other strains of the same species. Potency, water activity and enumeration results differ by strain and by production lot, so qualification must be strain-based.
Compare these related grades before approval:
For a substitution review, compare botanical identity, plant part, assay target, analytical method, physical form and the current offered-batch COA.

Frequently Asked Questions
How is lot traceability handled?

Is the declared percentage a specification limit or a measured result?
The specification figure is Not less than 1.0 x 10^11 CFU/g; the measured result for your lot is reported separately on its COA.
How long can we hold stock before use?
Two years when stored properly from the manufacture date when the pack stays sealed and dry.
Which particle size or presentation applies?
98% through 80 mesh
What happens to viability during transport?
The declared count is Not less than 1.0 x 10^11 CFU/g; shipping conditions and the receiving test are agreed so the count is verified on arrival.
Can you produce to our own specification or packing?
Alternative assay targets, particle size, packing and private-label requirements are reviewed case by case, subject to production feasibility and a revised written specification.
What packing options are available?
Standard packing is a sealed food-grade inner liner inside an export carton or fibre drum. Pack size, labelling and private-label artwork are agreed in the written specification.
Which documents come with the shipment?
Batch COA, specification sheet, agreed third-party testing where required, commercial invoice, packing list, certificate of origin and transport documents. The exact set is confirmed against the product and destination market.
