FIG. 1.
Growth kinetics of B. subtilis and S. aureus deletion mutants. (A) Growth curves are depicted for the B. subtilis tagA deletion strain (EB1494 [○]). Growth data for the wild-type (EB6 [▪]) and tagO deletion (EB1451 [•]) strains (9) are shown for comparison. (B) Growth curves are shown for the S. aureus wild-type (SA178RI [▪]), tarO null (EBII44 [•]), and tarA null (EBII58 [○]) strains. All cultures were inoculated to a starting optical density value at 600 nm (OD600) of 0.005, and absorbance measurements were taken every 1 to 2 h.
