Colony-forming efficiency of BW25113-based recombinant E. coli strains. Each strain was grown on LBGMg agar medium containing ampicillin (50 μg/ml) and isopropyl-β-d-thiogalactopyranoside (IPTG; 0.5 mM) in the absence of an organic solvent (A) and in the presence of n-hexane (B). Each strain was spotted at a tenfold dilution and incubated at 25 °C for 48 h
