Three strains with technological and probiotic properties (Lactococcus lactis INIA 650, Lacticaseibacillus paracasei INIA P272 and Bifidobacterium breve INIA P734) were used in different combinations as adjunct cultures for the manufacture of pasteurized ewe's milk. The three strains showed good viability during cheese manufacture and ripening. Moreover, they all were able to survive after the addition of the cheese samples to an in vitro colonic model. The nisin-producing strain L. lactis INIA 650 was able to produce the antimicrobial peptide nisin not only during cheese manufacture and ripening, but also in the colonic model. None of the strains combinations added to the cheese as adjunct cultures had a negative influence in their physicochemical or sensory characteristics when compared to control cheese. This work shows the suitability of cheese as vehicle for a multi-strain combination with potential dual effect in food and gut.
