Abstract

To investigate bile salt hydrolase activities of the bacterial strains isolated from fermented milk products, 21 strains of Lactobacillus were tested for their abilities to produced cholic acid from taurocholic and glycocholic acids. The production of cholic acid was measured by HPLC analysis during the growth in broth media for 24hrs. All strains of Lactobacillus acidophilus and L. plantarum deconjugated both taurocholate and glycocholate, whereas none strains of L. delbrueckii subsp. bulgaricus, L. casei subsp. casei, L. casei subsp. rhamnosus, L, reuteri did. L. acidophilus stains isolated from yogurts had the higher decojugation activities on glycocholate than taurocholate, however, L. acidophilus 1009 isolated from the human intestine showed the similar deconjugation activities on both taurocholate and glycocholate.
