摘要：

The effect on growth of a conjugated bile salt (sodium taurocholate) at physiological concentration was determined using cultures of Lactobacillus strains of murine origin. The bile salt stimulated the growth of one strain, did not affect the growth of another, but inhibited the growth of strains that produced relatively large amounts of the enzyme bile salt hydrolase. Comparison of the growth of isogenic strains that differed in the ability to produce bile salt hydrolase demonstrated that inhibition of growth was due to the accumulation of cholic acid in the culture medium as a result of the enzyme activity.
