A Growth curves of S. pneumoniae D39 in low pH (4.5) in the presence of DMSO or indicated concentrations of stevioside. B Bacterial viability of S. pneumoniae D39 in 10 mM H2O2 in the presence of DMSO or indicated concentrations of stevioside. All data from three technical replicates (A) or biological replicates were presented as mean ± SD. Unpaired two-tailed Student’s t-test was performed to determine the statistical significance of two groups. *P < 0.05, **P < 0.01 compared with the DMSO control group.
