Table 2 Specific bile salt hydrolase (BSH) activity of Lactobacillus strains toward six bile salts and a bile salt mixture. Values are means of triplicates repeats ± standard error of means. Means within a column with different lowercase letters are significantly different (P < 0.05). Means within a row with different uppercase letters are significantly different (P < 0.05). TC Sodium taurocholic, TCD sodium taurochenodeoxycholic, TCDC sodium taurodeoxycholic, GC Sodium glycocholic, GCD sodium glycodeoxycholic, GCDC sodium glycochenodeoxycholic
