Iron-detected chromatograms of FTSs. a Average of 8 FTSs (black) and simulations (red); b average of 4 FTSs harvested during mid-exponential growth; c average of 4 FTS from cells supplemented with 100 µM Fe(III) citrate and harvested during mid-exponential growth; d un-supplemented FTS replicate incubated with 500 µM BPY and simulations for remaining peaks from a in red. Offset in d is the same trace but × 3
