Effects of the pO promoter sequence on the pBAD promoter activity. a–c Activity of selected mutants from − 10 (a), − 35 (b) and whole promoter (c) libraries in LB medium, in the absence (upper panels) or presence of 0.1% arabinose (lower panels). d–f GFP fluorescence of each construct in respect to the wild type pBAD promoter. Asterisks indicate significant differences (t test, p < 0.05)
