Bifidobacterium

Bifidobacterium refers to a genus of Gram‑positive, anaerobic bacteria that naturally occur in the human and mammalian gastrointestinal tract. In food supplements it is typically present as live cultures identified at species level and often at strain level, shown on labels with a Latin name plus a strain code or number. Because many bifidobacteria are sensitive to oxygen and moisture, common presentations are capsules or powders using protective technologies (e.g., protective matrices or microencapsulation) and the amount is usually expressed as CFU. In cosmetics, the genus name is most often encountered through fermentation-derived materials, such as Bifida Ferment Lysate or related ferment filtrates, which are not necessarily live microorganisms. These fermented materials are used in water-based formulas such as serums and creams as soluble biotech ingredients. In practice, “Bifidobacterium” on an ingredient list may indicate either an oral probiotic culture or a topical ferment derivative, so the exact meaning depends on the form stated on the label.
