The probiotic effects of lactic acid bacteria (LAB) depend on their tolerance to the human gastro-intestinal tract. The acid and bile salt tolerance of four exopolysaccharide-producing strains of Lactobacillus plantarum was examined by the measurement of optical density at 600 nm (OD600 nm) and the plate colony counting. The results showed that the strain F401④ had higher acid tolerance capacity, and F201⑥ had the highest bile salt tolerance capacity which showed more than 100% survival rate after culture for 4 h in the presence of 0.3 and 0.5 g/100 mL bile salt.
