After 3 h incubation in PBS at pH 2.5 the number of viable LAB decreased from 8.0 to 6.0
log CFU/g. This result indicated that the strain exhibited high level of survival in simulated gastric juice when delivered in Potato Cheese. This is in agreement with findings for other LAB strains like L. casei 373; L. rhamnosus GG 53103; Yomix 205 (a probiotic mix containing L. bulgaricus, L. acidophilus, Bifidobacterium spp. and Streptococcus thermophilus) (Abadía-García et al., 2013).
