Bifidobacterium animalis subsp. lactis
What Is Bifidobacterium animalis subsp. lactis Used for in MicroBiome-18?
Bifidobacterium animalis subsp. lactis is a widely used probiotic bacterium valued for its stability in commercial foods and supplements.
It is frequently abbreviated as B. animalis subsp. lactis or simply B. lactis on product labels. Numerous named strains exist, and their research findings should not be treated as interchangeable.
The History of Bifidobacterium animalis subsp. lactis
This organism was historically treated as a separate species called Bifidobacterium lactis. Genetic research later supported its classification as a subspecies of Bifidobacterium animalis.
The older abbreviated name remains common in the food and supplement industries, which can make ingredient lists appear to contain two separate organisms when the naming overlaps.
Where Does Bifidobacterium animalis subsp. lactis Come From?
Commercial strains are associated mainly with:
- Probiotic dairy foods
- Fermented milk cultures
- Dietary supplements
- Controlled microbial culture collections
It is cultivated commercially rather than harvested directly from an animal or food source for each batch.
How Is It Manufactured?
A selected strain is grown under low-oxygen fermentation conditions. It is then concentrated and commonly freeze-dried with protective materials.
Manufacturers test identity, strain purity, viable count, and stability. Selected strains are known for tolerating industrial processing relatively well compared with some other bifidobacteria.
What Does Bifidobacterium animalis subsp. lactis Do?
The organism ferments selected carbohydrates and produces organic acids that participate in the intestinal microbial environment. Certain named strains have been studied for digestive and immune-related outcomes, but those findings remain strain-specific.
Common Uses
- Probiotic yogurt and fermented milk
- Capsules and powders
- Functional foods
- Synbiotic products
- Research involving bowel and immune functions
Why Is It Included in Probiotic Supplements?
It is frequently selected because certain strains remain viable during food processing and storage. It also gives a formula representation from the Bifidobacterium group.
Why MicroBiome-18 Contains Bifidobacterium animalis subsp. lactis
MicroBiome-18 lists Bifidobacterium animalis subsp. lactis within its 17-organism probiotic complex.
The manufacturer does not identify a named strain or individual amount. Claims tied to strains such as BB-12® should therefore not be automatically applied to MicroBiome-18.
Interesting Facts
- It was historically called Bifidobacterium lactis.
- The abbreviated name B. lactis is still widely used.
- Different commercial strains can have different evidence.
- Selected strains are valued for manufacturing stability.
