Effect of Fe on SCM1 specific growth rate (µ) in EDTA-buffered experiments wherein the available substrate is Fe´ (solid bars) and DFB buffered experiments wherein there is negligible Fe´ and all Fe is bound to DFB (FeDFB—open bars), and effect of Fe(II) specific chelator, ferrozine (FZ) on specific growth rates of SCM1 in these cultures (+FZ). n.g. indicates no SCM1 growth. Concentrations on x-axis indicate the available substrate (i.e. Fe´ or FeDFB). Error bars indicate standard deviation, n = 11
