Strain EP7T takes up the FITC-labelled model polysaccharide dextran. Structured illumination microscopy of strain EP7T cells incubated with DAPI (DNA stain), FITC-labelled dextran, and Synaptored (membrane stain). Fluorescence signals of the FITC-labelled dextran (green) co-localize with the fluorescence signal of the membrane stain (red) indicating an uptake of the polysaccharide into the periplasmic space. The DNA appears as condensed foci and is located in the cytoplasm next to the cytoplasmic membrane and periplasmic invaginations. Scale bars represent 2 μm.
