Description
Bifidobacterium animalis is supplied at the species level when the customer requires the broader B. animalis taxonomic designation (covering both subsp. animalis and subsp. lactis). The species is hardy, oxygen-tolerant compared to other bifidobacteria, and well-suited to capsule and dairy applications.
Supplied as a freeze-dried powder with viability between 200 and 500 billion CFU per gram at release. Robust industrial behavior makes B. animalis a workhorse Bifidobacterium for multi-strain blends.
Off-white to pale beige free-flowing powder with a neutral odor. Particle size suitable for capsule, sachet, and dairy applications.
We supply food-grade Bifidobacterium animalis from manufacturers in China holding ISO 22000, FSSC 22000, Halal, Kosher, and other certifications relevant to probiotic strain production.
Common market grades include 200, 300, and 500 billion CFU per gram freeze-dried powders, microencapsulated grades, and direct-vat-set frozen concentrates. Both subsp. animalis and subsp. lactis derivations are available on request. Bulk and reduced-MOQ shipments with batch-level COA covering viable count, strain identity, moisture, heavy metals, and pathogen panel.
Introduction
Bifidobacterium animalis was originally isolated from animal feces and later subdivided into subsp. animalis (the type subspecies) and subsp. lactis. Reference strains include ATCC 25527 for subsp. animalis and DSM 10140 for subsp. lactis.
Industrial production follows the same general process as other Bifidobacterium species: anaerobic batch fermentation in semi-defined media, biomass recovery under nitrogen blanket, cryoprotectant blending, and lyophilization. The B. animalis lineage is the most robust of the commercial bifidobacteria, supporting reliable industrial production at scale.
Regulatory status includes GRAS notifications with FDA for multiple specific strains, Qualified Presumption of Safety listing in the European Union, and approval for use in infant formula in major regulatory regions.
Clinical evidence supporting subsp. lactis (the more clinically documented subspecies) covers bowel regularity, immune function, and as part of multi-strain blends for IBS symptom management.
The B. animalis species occupies a central position in industrial probiotic supply and is often specified at the species level in private-label and multi-strain blend formulations.
