Dairy propionibacteria are gram positive, aerotolerant and mesophilic bacteria found in dairy products, and in diverse habitats such as soil, plants, and digestive tracts of ruminants. They are essential as ripening culture in the manufacture of emmental and other swiss type cheeses so they are consequently consumed in a high amounts by consumers. Dairy propionibacteria are also considered for their probiotic use. Indeed, they are species with low nutritional requirements, and with high resistance and tolerance capacities towards stresses, as acid and bile salts. Some strains (species) were shown to survive in human gut, where they may have health-promoting activities. In this review, we summarize the knowledge on the interactions between probiotic dairy bacteria and the intestinal epithelium. We focus on the metabolites that are likely to play a probiotic role in the colon, as well as the adhesion capacities to mucus and epithelial cells of the propionibacteria. Then among the probiotic potentialities, the immunomodulatory capacities of the dairy propionibacteria are detailed.
