Abstract
This study was carried out to isolate and characterize the Lactobacillus plantarum with bile salt deconjugation activity that was isolated from Kimchi. Some isolates were selected and identified as L. plantarum by 16S rRNA gene sequence and sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) analysis of whole cell protein patterns. They were assayed to determine their capacities to express bile salt hydrolase (BSH) activity. Among the identified strains, L. plantarum CIB 001 showed the highest level of BSH activity. Then, resistance to gastric acidity and bile condition were analyzed for further characterization. This strain was able to maintain viability for 1h at pH 2.0 and to survive in a MRS (deMan, Rogosa, and Sharpe) broth with 1.0% of bile acids. L. plantarum CIB 001 would potentially be useful in the food industry as probiotics.
