The pH values and bile concentrations represent the means of three replicates. Student t-test was used for comparison of the mean survival at pH 2 and 3. Values with different superscript letters (a-o) in the same column and different superscripts with capital letter across the row are significantly different (p < 0.05). Multiple comparisons for bile tolerance were done using Tukey’s HSD
