Bifidobacterium adolescentis is an obligately anaerobic, non-motile, non-spore-forming Gram-positive rod with a characteristic bifurcated morphology, classified in the family Bifidobacteriaceae within the phylum Actinomycetota. It is one of the dominant bifidobacterial species in the adult human gut, where it ferments dietary oligosaccharides and starch via the bifid shunt pathway, producing acetate and lactate that contribute to gut health. B. adolescentis has been shown to promote Th17 cell differentiation and immune homeostasis, and its genome encodes a large repertoire of glycoside hydrolases, reflecting its specialisation in complex carbohydrate utilisation.

How to read this: A value outside a failure limit fails QC. Within the failure limits, values beyond a warning limit are borderline and worth a manual look; values within the warning limits pass that criterion. A dash means that no bound is defined on that side.
