Effect of low pH on the sensitivity of S. Typhimurium to novobiocin. 106 mL-1 cells of S. Typhimurium 14028s strain in M9 medium pH 7 (grey bars) or pH 4.7 (black bars) were treated with 0.15 μM novobiocin or sterile bidistilled water as control. CFU mL-1 was determined after 0, 6 and 24 h of incubation at 37°C. Results are expressed as percentage of surviving bacteria to novobiocin relative to the control in the absence of the antibiotic. Error bars represent standard deviations from five different experiments.
