FIG 4.
Regulation of the A. baumannii ethanol-inducible adhP (A) and yahK (B) genes. A. baumannii ATCC 19606T carrying either pLPV1Z::PadhP or pLPV1Z::PyahK was cultured overnight in LB broth, diluted at an OD600 of 0.1 in LB broth, and challenged with different ethanol concentrations, as indicated. The luminescence emission was recorded at 15 min postinduction. Gray and black histograms indicate pLPV1Z::PadhP (A) or pLPV1Z::PyahK (B) fusions and the promoterless pLPV1Z vector, respectively. Data are the means ± standard deviations from three independent experiments.
