Discovery and Characterization of Iron Sulfide and Polyphosphate Bodies Coexisting in Archaeoglobus fulgidus Cells

Figure 5

Separate EDX analysis of two granules in a single intact A. fulgidus cell. (a) STEM image of the analyzed cell; the first area scanned by the probe is shown as an orange box. The two granules are labeled as G#1 and G#2. (b) The EDX area scans for each element found in the region specified in (a), which contains G#1. Each element is plotted in a different color. (c) The individual EDX point spectrum from the location specified in (a) and (b) by a cross with the number 1. (d) STEM image of the analyzed cell; the path of the probe for the second scan is shown as an orange line. (e) The EDX line spectra across the cell shown in (d), which contains G#2. Each element is plotted in a different color. (f) The individual EDX point spectrum from the location specified in (d) by a cross with the number 1 and in (e) by a vertical line.
