TEM images of Iron Biomineralization Patterns in a Denitrifying As(III)-Oxidizing Bacterium

Relating to Figure 4 in paper<br><br>"Elucidating Heterogeneous Iron Biomineralization Patterns in a Denitrifying As(III)-Oxidizing Bacterium: Implications for Arsenic Immobilization" DOI 10.1039/d1en00905b<br><br>This is TEM data of Iron Biomineralization Patterns in a Denitrifying As(III)-Oxidizing Bacterium<br><br>Taken on Jeol F200 using Nanomegas system 200kV 100pA<br><br>TEM micrographs of planktonic ST3 samples at days 1 (A and B), 3 (C and D) and 7 (E and F). Mineralized cells can be observed from day 1, showing a thicker mineralization by day 3 and the appearance of a more crystalline structure by day 7. The red squares in (A)-(C) highlight the cell poles with heavier mineralization than the rest of the cell. (E) is a selected region with “flake-like” biominerals at higher magnification in (F). A, C &amp; E are indicating the nanoparticles aggregated as filaments associated with the cell surface.
