Proteus mirabilis strain HI4320 (WT) and isogenic mutants for dsdA, dsdC, or dsdX were cultured in LB broth overnight and diluted 1:100 into fresh LB (A), PMSM (B), PMSM containing 10 mM d-serine as the sole source of carbon (C), PMSM containing 10 mM d-serine as the sole source of nitrogen (D), PMSM containing 10 mM l-serine as the sole source of carbon (E), or PMSM containing 10 mM l-serine as the sole source of nitrogen (F), and growth was assessed as described in the legend for Fig. 1.

Error bars represent means ± standard deviations (SDs) from at least 6 replicates, and graphs are representative of 3 independent experiments. In PMSM with d-serine as the sole source of carbon or nitrogen, the WT exhibited significantly increased growth compared to that of the mutants by paired two-way ANOVA with Dunnett’s test for multiple comparisons (P < 0.001).
