All bile acids, depending upon their concentration can inhibit the growth of bacteria. However, probiotic bacteria vary considerably in their levels of bile tolerance (Gotcheva et al., 2002; Kruszewska et al., 2002). In our study, isolates could not tolerated presence of oxbile (0.3%) in the growth medium while few isolates showed modest growth in the same medium with another bile sodium taurocholate (0.3%). Addi- tionally, it is documented that bile resistance of some strains vary considerably among the LAB species and between strains themselves (Gu et al., 2008). Two isolates belonging to same
