All
tested strains exhibited survival during simulated gastric transit at pH 3 for 3 h. Lactobacillus

Streptococcus thermophilus 1342, Bifidobacterium lactis BB12 and S. thermophilus M5
were found intrinsically tolerant to gastric and small intestinal transit and most tolerant
strains among tested LAB (% survival ≥ 55).
