Assessment of the probiotic properties of E. lactis 10NA and E. lactis 50NA strains. A Acid survivability percent of the two strains in MRS media with pH adjusted at 3; the control was plain MRS media with pH 6.5. B Growth curves (log CFU/ml) of the two strains in MRS media with 0% (control), 0.3%, and 0.7% (w/v) bile salts concentrations. The values are presented as the means ± SD of three independent experiments. “*” indicates a significant difference where “*”P-value < 0.05 and “**”P-value < 0.01
