Fig. 6.

(a) Relative cell viability of L. plantarum after exposure to simulated gastric juice at pH 2.0 and pepsin (0.3 %) for 4 h at 37 °C. Significant difference in the relative cell viability was obtained between wall systems (p < 0.05). (b) Relative cell viability of L. plantarum after exposure to simulated bile juice (2 %) for 4 h at 37 °C. Significant difference in the relative cell viability was not obtained between wall systems (p < 0.05). Error bars represent standard deviation of means (n = 3)
