Table 1.

Microbial concentration of the digested samples (final counts) and the survival percentage of L. salivarius to each stage (oral, gastric, and intestinal) and the entire simulated digestion (total) as affected by the food matrix and the growing media. Mean value ± standard deviation of triplicates from two independent treatments.

abcde different superscripts in the same column indicate statistically significant differences (p-value < 0.05). XUFlb are the colony counts of undigested food (cfu/g dw); XOSlb are the colony counts at the end of the oral stage (cfu/g dw); XGSlb are the colony counts at the end of the gastric stage (cfu/g dw); and XISlb are the colony counts at the end of the intestinal stage (cfu/g dw).
