D-Ala inhibit the growth of Proteobacteria bacteria. (A) The growth of microbiome in 1% D-aa containing medium. Each sample was collected at the indicated time points and the optical density was measured at 620 nm. ∗∗∗P < .001. P values were obtained via analysis of variance with Tukey’s post hoc test. Data are shown as standard error of the mean. (B) Correlation between D-aa and growth of microbiota in vitro. A color code of dark blue indicates a positive correlation coefficient close to +1, and a color code of dark red indicates a negative correlation coefficient close to −1.
