The S. aureus dacA mutant can grow in CDM but not in TSB medium. A, bacterial growth on agar plates. WT LAC* and the isogenic dacA mutant were streaked on TSA or CDM plates, and images of plates were taken after overnight incubation at 37 °C. B, plating efficiencies. Bacterial suspensions were prepared for the WT and dacA mutant strains, and appropriate dilutions were spread on TSA or CDM plates and CFUs per ml of culture per A₆₀₀ unit determined and plotted. The average values and standard deviations from four biological replicates were plotted.
