STRAIN-IDENTIFIED CULTURE RANGE
Probiotic Strains
This range covers freeze-dried, strain-identified probiotic cultures for B2B blends. Every product page states the species, the strain designation and the achievable potency, because strain identity and delivered CFU, not species name alone, define the purchasing specification.

|---|---|
| Material class | Freeze-dried probiotic cultures, lactobacilli, bifidobacteria, bacilli and yeasts |
| Identity basis | Species and strain designation, stated per product page |
| Potency | Up to 1.0 x 10^12 CFU/g depending on strain and lot |
| Format | Freeze-dried powder |
| Documentation | Batch COA with enumeration result, specification sheet, strain documentation |

How to choose within this range
| Your requirement | Specification to fix | Why |
|---|---|---|
| A specific health-positioning strain | Fix the strain designation | Different strains of the same species are not interchangeable |
| Shelf-life potency | Fix the CFU basis and required overage | Potency at delivery and at end of shelf life are different claims |
| Dry blending | Confirm water activity and particle size | These drive viability loss and dispersion |
| Comparing suppliers | Ask for enumeration method and lot data | Plate count, flow cytometry and qPCR report differently |
Purchasing and delivery
- Evaluation sample typically 10-20 g, subject to stock
- Regular MOQ typically 1 kg

Qualification and COA review
Every culture page cites a representative batch and the potency basis. Final acceptance requires the approved specification, the current lot COA with an enumeration result, and confirmation of strain identity documentation.

Frequently Asked Questions
Why is the strain designation important?
Because probiotic characteristics are strain-specific. Two strains of the same species can differ in behaviour, documentation and permitted claims.
How is potency expressed?
As CFU per gram or per dose. Confirm which basis your quotation uses, because the two are not interchangeable.
Which enumeration method is used?
The method is stated on the COA. Plate count, flow cytometry and molecular methods report on different bases and should not be compared directly.
What should be considered for packing and transport?
Water activity, oxygen and temperature exposure all affect viability. Confirm packing format and any cold-chain requirement before ordering.
Are you a manufacturer or a trading company?
We are Shaanxi Longsheng Biotechnology Co., Ltd., a direct manufacturer integrating R&D, production and export support. Factory review may be arranged by video or an on-site visit.
Can I request the current batch COA before ordering?
Yes. Request the applicable current or representative COA for each shortlisted grade and compare identity, method, limits and results.
What is the minimum order quantity?
The regular MOQ is typically 1 kg. Evaluation samples of 10-20 g may be arranged subject to stock.
Can specifications or packaging be customised?
Selected assay targets, particle size, carrier and packing may be reviewed case by case before quotation.
