The effect of bile salts was tested on a collection of 38 strains of Lactobacillus isolated from a probiotic bacterial consortium Half of the strains were slightly affected by 0.3% bile salts showing a delay of growth below 1 h, to reach an absorbance of 0.3 at 600 nm in MRS broth, compared to a reference curve without bile salts. According to the heterogencity of sensitivity, the resistance to bile salts should be checked for the selection of probiotic strains of Lactobacillus.
