Fig. 1From: Involvement of catalase and superoxide dismutase in hydrophobic organic solvent tolerance of Escherichia coliColony-forming efficiency of E. coli BW25113 and its mutants deficient in ROS-scavenging enzymes on LBGMg agar medium. Each strain was grown 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 hBack to article page
