Fig. 1From: The influence of oxygen and oxidative stress on de novo acquisition of antibiotic resistance in E. coli and Lactobacillus lactisAcquisition of resistance to amoxicillin (A, E, I), enrofloxacin (B, F, J), kanamycin (C, G, K), and tetracycline (D, H, L) of E. coli wild-type MG1655 (blue: anaerobic/black: aerobic) and the ΔoxyR knockout (green: anaerobic/red: aerobic) strains. The Y-axis indicates the antibiotic concentration at which the cells were able to grow. The top 4 panels (A-D) show wild-type MG1655, the second set of panels (E-H) show the ΔoxyR mutant, and the third set of panels (I-L) compares the resistance concentrations of each strain reached at day 20Back to article page
