57Fe Wall Loss Experiment data collected as part of a method development study investigating the precipitation and wall loss of labeled 57Fe when added to M9 Minimal Media

<p>This data was collected as part of a method development study investigating the precipitation and wall loss of labeled ⁵⁷Fe when added to M9 Minimal Media, which is used to grow the model bacterial species <em>Escherichia coli.</em> The bulk media was prepared with the same components and a portion was treated with Chelex-100 to remove metals, while the other portion remained un-chelexed. Half of each treatment was spiked with labeled ⁵⁷Fe and either 0.2 μm or 0.02 μm filtered for comparison of the dissolved and soluble fractions. The ⁵⁷Fe content was monitored over four time points for one week in a shaking incubator, under the same conditions used to culture <em>E. coli</em> for labeling experiments.</p>
