在从益生菌聚生体分离的38株乳杆菌属菌株的集合上测试胆汁盐的作用。与不含胆盐的参考曲线相比，一半菌株受到0-3%胆盐的轻微影响，显示生长延迟低于1小时，在MRS肉汤中在600 nm处达到0.3的吸光度。根据敏感性的异质性，在筛选乳酸杆菌益生菌株时应考察其对胆盐的抗性。
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 heterogeneity of sensitivity, the resistance to bile salts should be checked for the selection of probiotic strains of Lactobacillus.
