Figure 3
Microtomographic cross sections of E. coli pellets embedded in glass capillaries. Linear absorption coefficients are shown in gray scale from 0 cm−1 (black) to 30 cm−1 (white). Scale bar: 50 µm. (a) Ferritin-expressing recombinant with iron supplementation in LB medium. (b) Ferritin-expressing recombinant without the iron supplementation. (c) Mock recombinant with the iron supplementation. (d) Mock recombinant stained with phosphotungstic acid. (e) Histogram of absorption coefficients of the E. coli pellet shown in (a).
