Probiotic bacteria: Selective enumeration and survival in dairy foods

Open access
Shah, N.P.·2000·Journal of Dairy Science

Abstract

A number of health benefits have been claimed for probiotic bacteria such as Lactobacillus acidophilus, Bifidobacterium spp., and Lactobacillus casei. Because of the potential health benefits, these organisms are increasingly incorporated into dairy foods. However, studies have shown low viability of probiotics in market preparations. In order to assess viability of probiotic bacteria, it is important to have a working method for selective enumeration of these probiotic bacteria. Viability of probiotic bacteria is important in order to provide health benefits. Viability of probiotic bacteria can be improved by appropriate selection of acid and bile resistant strains, use of oxygen impermeable containers, two-step fermentation, micro-encapsulation, stress adaptation, incorporation of micronutrients such as peptides and amino acids and by sonication of yogurt bacteria. This review will cover selective enumeration and survival of probiotic bacteria in dairy foods.

  • A probiotic must survive extremely low pH levels and the presence of bile salts and reach the gut in a viable physiological state to colonize and proliferate in this environment to confer beneficial effects on the host.

    “The probiotic must survive the extremely low pH levels and the presence of bile salts and reach the gut in a viable physiological state to colonize and proliferate in this environment to confer beneficial effects on the host [33,34].”

    From Probiotic and Antifungal Attributes of Lactic Acid Bacteria Isolates from Naturally Fermented Brazilian Table Olives (2022) · cites this paper as [33]

    The “Selection of Acid and Bile Resistant Strains” section says probiotics need to survive stomach acid and intestinal bile. The “Bifidobacterium SPP.” section links sufficient viable numbers with therapeutic effects. Neither passage establishes that probiotics must colonize and proliferate in the gut; page numbers are unavailable in our copy. (LLM, conf=0.85)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
