Anr regulation of adhA expression. P. aeruginosa strains grown in M63 liquid medium with ethanol as the sole carbon source in a 0.2% oxygen atmosphere. The strains included wild-type strain PA14 (WT) and ΔadhA, ΔadhA adhA, Δanr, and Δanr anr mutants as well as a Δanr mutant containing an empty vector (pEV) or a plasmid with adhA under the control of an arabinose-inducible promoter (padhA). Statistics based on one-way ANOVA and Tukey’s multiple-comparison test; unless otherwise indicated, statistical comparisons are to the WT culture. ****, P < 0.0001; **, P < 0.01.
