Colony-forming efficiency of E. coli JA300 mutants on LBGMg agar medium with or without an organic solvent. Colony-forming efficiency of acrR and/or marR mutants on the agar medium in the absence of an organic solvent (A) and in the presence of n-hexane (B), cyclohexane (C), or cyclohexane and p-xylene (6:4 vol/vol mixture) (D). Colony-forming efficiency of acrA disruptants of JA300 and JA300 acrRIS marR on LBGMg agar medium in the absence of an organic solvent (E) and in the presence of decane (F), nonane (G), or octane (H). Each strain was spotted at a tenfold dilution and incubated at 25°C for 48 h.
