Growth of E. coli BW25113, BW25113∆katEkatG and BW25113∆sodAsodB in LBGMg liquid medium at 37 °C in the absence of an organic solvent (A) and in the presence of 10% (vol/vol) cyclooctane (B), 10% (vol/vol) n-hexane (C), or a 10% (vol/vol) n-hexane and cyclohexane mixture (9:1 vol/vol) (D). A 100-μl culture of an overnight-grown E. coli strain was inoculated into 10 ml of fresh LBGMg liquid medium containing an organic solvent. This two-phase culture was incubated at 37 °C. Growth was monitored by measuring turbidity (OD660). Symbols: filled circle, BW25113; open square, BW25113∆katEkatG; open triangle, BW25113∆sodAsodB. Values indicate the means and standard deviations of the results from three independent experiments
