Bacillus subtilis DSM 21097 – Factual information on the reference strain
Introduction
This page provides factual information about the microbial strain Bacillus subtilis DSM 21097. It is intended for individuals who deal with defined microbial strains professionally or out of personal interest and who value clear origin, unambiguous identification, and transparent production. The following content does not constitute health-related claims.
What is Bacillus subtilis?
Bacillus subtilis is a naturally occurring, rod-shaped microorganism belonging to the group of spore-forming Bacillus species. A characteristic feature of this group is the ability to form resistant spores. These spores are a natural survival form of the microorganism and provide high stability against environmental influences such as heat, dryness, and stomach acid.
Bacillus subtilis has been scientifically described for decades and is documented in international strain collections.
What does the designation DSM 21097 mean?
The abbreviation DSM refers to the German Collection of Microorganisms and Cell Cultures. There, uniquely identified strains from around the world are stored under a fixed number. The number 21097 refers precisely to this one, clearly defined strain of Bacillus subtilis.
Such a registration ensures that the same strain is always described, examined, and used worldwide. This allows for unambiguous identification regardless of the manufacturer.
What is meant by a spore shape?
Spores are a natural dormant form of certain microorganisms. In this form, the microorganism is particularly resistant to external influences. Under suitable conditions, the spores remain stable for long periods and can revert to their active form in the appropriate environment.
The spore shape is used in many technical applications because it facilitates transport, storage and standardized dosing.
What does the KFU (CFU) designation mean?
The abbreviation CFU stands for colony-forming units. It describes how many viable microorganisms are contained in a defined quantity. This value is given as a laboratory value and serves for quantitative classification.
A clear CFU (colony-forming unit) figure is a technical quality feature, as it provides transparency regarding the quantity of the strain used.
Manufacturing and quality control
Products containing Bacillus subtilis DSM 21097 are manufactured under controlled conditions. The strain's properties, spore shape, and dosage are tested batch-specifically. In addition, laboratory tests are performed to identify the strain and assess its microbiological quality.
Manufacturing in controlled production environments and regular laboratory testing ensure consistent technical quality.
Carrier substances and capsule shell
Suitable natural carriers are used to fill the capsules. Depending on the variant, plant powders or plant extracts are used. The capsule shells are made of HPMC and are vegan.
No technical additives such as release agents, colorants or preservatives are used.
Distinction from advertising presentations
Numerous overly simplified or promotional descriptions of microbial strains can be found in the trade. This page explicitly does not pursue a promotional approach, but serves solely to provide factual information about the reference strain mentioned here and its technical properties.
