FIG 5.

Growth of P. aeruginosa PA14 strains on ethanol as a sole carbon source. (A) Growth in M63 liquid medium with ethanol as the sole carbon source in 0.2% oxygen. (B) P. aeruginosa strains grown in M63 liquid medium with ethanol as a sole carbon source in anoxia with 50 mM KNO₃. Data are representative of at least three independent experiments, each with three or more biological replicates. Statistics are based on one-way ANOVA and Tukey’s multiple-comparison test; **, P < 0.01; ****, P < 0.001; ns, not significant. Statistics presented indicate differences from the WT unless otherwise indicated.
