Fig. 2 – Survival of probiotic strains (a) L. acidophilus
(CCFM6) and (b) L. plantarum (CCFM47) in simulated gastric
juice at pH 2.5 at 37 °C for 3 h in fermented skim milk
supplemented with or without 2% SBOs during storage at
4 °C for 21 days. * and † = survival of pure CCFM6 and
CCFM47 respectively under the same test conditions in
simulated gastric juice. Error bars represent the standard
error of the means, n = 3. SBOs, soybean oligosaccharides
