Active cultures of strain 630Δerm (black), the clnR mutant (MC885, light purple), the clnAB mutant (MC935, light blue), clnR Tn::clnRAB (MC950, dark purple), and clnAB Tn::clnRAB (MC953, dark blue) were diluted to an OD600 in 0.01 in minimal media (MM) either without (A-G) or with (H-N) 0.5 μg/ml LL-37. Base minimal media (A, H) or MM supplemented with 30 mM glucose (B, I), 30 mM fructose (C, J), 30 mM mannose (D, K), 30 mM mannitol (E, L), 30 mM N-acetylglucoseamine (NAG) (F, M), or 30 mM ethanolamine (EA) (G, N). Graphs are plotted as the means +/- SEM from three independent replicates. Data were analyzed by two-way ANOVA with Dunnett’s multiple comparison test, comparing to 630Δerm at each time point. Adjusted p value < 0.05 indicated by the symbols in the legend.
