Effect of vitamin K analogs on the growth and survival of strain EDL933 in the presence of H2O2, ciprofloxacin, and MMC. (A) H2O2 (measured by the increase in the number of CFU/ml); (B) ciprofloxacin (measured by the increase in OD600); (C) MMC (measured by the increase in OD600). Phylloquinone and menaquinone were used at a concentration of 72 μM, menadione at a concentration of 7 μM, and MSB at a concentration of 36 μM. The results are given as means from three independent experiments, with bars showing ±SD.
