Abstract excerpt

Three commercial phage-sensitive strains of Lactobacillus delbrueckii (strains Ab(1), YSD V and Ib(3)) and four spontaneous phage-resistant mutants (strains A(7), A(17), V(2) and I(39)) isolated from them, all with a probiotic potential previously demonstrated were studied for their tolerance of bile salts (ox gall). Minimal Inhibitory Concentrations (MICs) ranged from 0.30% to 0.35% (w/v) of ox gall. These...
