Resistance to bile salts and low pH (A) and adhesion to mucin (B) of the five most abundant lactobacilli genera. (A) Sensitivity to bile salts (3 g/L; striped boxes) and low pH (pH 3; dotted boxes) are expressed as the level of decrease in the viability of the tested strain in orders of magnitude relative to the viability of the same strain under control conditions (pH 7.4). (B) The level of adhesion to mucin is expressed in OD_583nm value - higher the OD signifies better adhesion capacity. Data is presented as a boxplot of obtained values (25th to 75th percentile with median line in the middle).
