STXM image of an ensemble of cells of Magnetovibrio blakemorei strain MV-1 deposited on a formvar coated 3 mm transmission electron microscopy (TEM) Cu grid.

The image was recorded at 709.8 eV and converted to optical density (OD) using the intensity in areas without cells in this image. The arrows indicate cells with apparent gaps in their magnetosome chains. The question marks (red) indicate (multiple) cells that were discounted because of uncertainty as to the number of cells and/or magnetosome chains present.
