Fig. 1. Growth inhibition of S. pneumoniae TIGR4 by SCFAs. S. pneumoniae TIGR4 (serotype 4) was cultured in media with or without various doses of (A) NaA, (B) NaP, and (C) NaB. The OD600 value was measured at 0, 1, 3, 6, 9, 12, or 24 h. (D) At the maximum growth time point of NT, the susceptibility is calculated as OD600 value of 100 mM SCFAs treated group divided by maximum OD600 value of NT. Data shown are representative of three independent experiments and indicate the mean value ± standard deviation of triplicate samples. Statistical significance was analyzed with Student’s t-test compared to NT or among SCFAs treated groups (*, P < 0.05). NaA, sodium acetate; NaP, sodium propionate; NaB, sodium butyrate; NT, non-treatment.
