Growth kinetics of recA, yeiH, asr, srlE, and manY deletion strains compared to wild-type parent E. coli BW25113. Growth kinetics of recA, yeiH, asr, srlE, and manY deletion strains compared to wild-type parent E. coli BW25113. Shown are the growth curves generated for strains BW25113, JW2669, JW2145, JW5826, JW5430, and JW1807 in LB (control); LB supplemented with 10 mM GSH (GSH); LB with 3 ng of ciprofloxacin/ml (Cip); and LB supplemented with 10 mM GSH and 50 ng of ciprofloxacin/ml (GSH+Cip).
