Lactic acid bacteria (LAB) are food-grade and non-toxic probiotic organisms. Therefore, they are generally recongnized as safe (GRAS). Consumption of LAB and fermented dairy products can decrease serum cholesterol level. In this study, it was performed to screen and select indigenous LAB from Kimchi as potential probiotics. Analysis of 16S rRNA gene sequences of probiotic strain indicated that BCNU 9070 strain was a member of Pediococcus pentosaceussp. Pediococcus pentosaceus BCNU 9070 showed resistance to gastric juice and bile. In addition, BCNU 9070 strain expressed bile salt hydrolase activity, and had ability to assimilate cholesterol in vitro. BCNU 9070 strain also inhibited cell growth of five food-borne pathogens including Listeria monocytogenes and Shigella sonnei.. According to these results, Pediococcus pentosaceus BCNU 9070 is determined to be potential probiotic strain with functional abilities.
