SssF activity is detected in a S. aureus heterologous complementation approach. (A) Relative survival of S. aureus SH1000 wild-type, SH1000sasF isogenic mutant and sasF, sssF and vector only complemented strains on agar medium containing 1 mM linoleic acid. Heterologous complementation of the S. aureus SH1000 sasF mutant with the sssF gene from S. saprophyticus MS1146 restores survival in these conditions. Serial dilutions of overnight S. aureus cultures (2.5 μl) were spotted onto BHI agar, pH 6.0, containing 0 mM and 1 mM linoleic acid, 1% ethanol. The neat to 10-6 dilutions are as indicated. Shown are representative images from one of multiple experiments. (B) Graph showing the relative survival of S. aureus SH1000 and SH1000 derivates using data from Figure 5A. Colonies were counted after overnight incubation. Error bars represent ± SEM. Results from multiple experiments were analysed with Student's t test.
