Fig. 6. Growth inhibition of nonencapsulated S. pneumoniae by SCFAs. S. pneumoniae (A) D39, (B) R36A, and (C) R6, were cultured in media with or without various doses of SCFAs. The OD600 value was measured at 0, 1, 3, 6, 9, 12, or 24 h. (D) At maximum growth time point of each NT, the susceptibility is calculated as OD600 value of 100 mM SCFAs treated group divided by maximal OD600 value of each NT. Data shown are representative of three different experiments and indicate the mean value ± standard deviation of triplicate samples. Statistical significance was analyzed with Student’s t-test compared to NT or encapsulated strain (*, P < 0.05). NaA, sodium acetate; NaP, sodium propionate; NaB, sodium butyrate; NT, nontreatment.
