Lactobacillus Delbrueckii Subsp Lactis Postbiotics
Lactobacillus Delbrueckii Subsp Lactis Postbiotics is an inactivated preparation of Lactobacillus delbrueckii subsp. lactis, processed under controlled industrial conditions to yield a defined postbiotic ingredient containing heat-killed bacterial cells, cell wall fragments, fermentation metabolites, and exopolysaccharides.
The species sits within the same taxonomic group as Lactobacillus delbrueckii subsp. bulgaricus, the classic yogurt-starter organism, and shares many of its metabolic and structural traits.
We source bulk Lactobacillus Delbrueckii Subsp Lactis Postbiotics from top China manufacturers for our partners. The manufacturer is in Jiangsu. A smaller requirement can ship in a combined container with other ingredients.
Please send the grade you need, the volume and your destination port, and we will come back with a solution and a price.

Common Markets Grades
The ingredient is produced primarily as a spray-dried powder with moisture below 6 percent and standardised total dead-cell count.
Cell-count specifications typically range from 100 billion to 1 trillion inactivated cells per gram, depending on customer specification.
The carrier matrix is most often maltodextrin or skim milk powder, with allergen status declared accordingly.
A concentrated liquid format is produced for liquid beverage applications, sold at 25 to 40 percent total solids and standardised to a defined lactic acid content.
Strain identity is documented at the subspecies level by 16S rRNA sequencing and species-specific PCR.
Each lot is qualified for moisture, total dead-cell count, residual viable count (below specification limit), Enterobacteriaceae, yeasts and moulds, and Salmonella.

How We Help Source Lactobacillus Delbrueckii Subsp Lactis Postbiotics
Direct Factory Sourcing
We run the whole process: selecting the manufacturer from the top Chinese food ingredient producers, negotiating the price, verifying quality, and coordinating the logistics. You deal with us instead of with several factories at once.
Original Packaging and Documents from the Manufacturer
The manufacturer sends your Lactobacillus Delbrueckii Subsp Lactis Postbiotics out of its own factory in the original packing, through to your destination port. The COA, COO, MSDS, TDS and any certifications reach you from the manufacturer as well.
Free Samples and Lead Time
We send 100 to 500 g free for your own laboratory to test and you cover only the courier, usually within 2 to 3 working days. ETD is usually within 7 to 15 days once the order is confirmed, and we check that date against the factory's own manufacturing schedule before we give it to you.
Combined Shipment
We can load Lactobacillus Delbrueckii Subsp Lactis Postbiotics together with other ingredients such as Postbiotics, Yeast β-Glucan and Selenium Enriched Yeast into one 20' FCL. If your quantity is small, we can also ship LCL.
Regulatory Status
Lactobacillus Delbrueckii Subsp Lactis Postbiotics is regulated as a postbiotic food ingredient rather than a live probiotic.
Because the bacterial cells are inactivated, the ingredient does not require the regulatory authorisations applicable to live probiotic strains.
In the U.S. it is typically used under self-affirmed GRAS or FDA GRAS notification depending on strain identity and use level.
In the EU it is treated as a food ingredient under the Novel Food framework if not previously consumed in significant amounts before 1997, or as a traditional food ingredient if a history of safe use can be documented.
The 2021 ISAPP consensus definition of postbiotics covers preparations of this type.
Cosmetic use is regulated under the EU Cosmetics Regulation and listed in the CosIng database when sold under a defined INCI name. Halal, Kosher, and non-GMO certifications are routinely available.
Manufacturing Process
Production begins with revival of a defined Lactobacillus delbrueckii subsp. lactis strain from a working cell bank.
The culture is propagated through staged seed fermenters into a production-scale stirred-tank fermenter, typically of 5,000 to 30,000 litre working volume.
The medium is based on lactose or glucose as the primary carbohydrate, with a dairy or plant-based nitrogen source and a defined mineral and vitamin package.
Fermentation runs at 40 to 45 degrees Celsius, the species' thermophilic optimum, under microaerophilic conditions for 14 to 24 hours, with pH controlled by automated alkali addition.
At the end of fermentation, the culture is heat-treated at 80 to 95 degrees Celsius to inactivate cells while preserving the bioactive cell wall structures.
The inactivated broth is concentrated by ultrafiltration or vacuum evaporation, then spray-dried with the chosen carrier. Each lot is verified by total dead-cell count, lactic acid assay, residual viable count, and microbial safety panel.
