 Visualization using Transmission electron microscopy (TEM) confirms star-like protrusions on the outer membrane (6-8 nm thick).The periplasmic space is exceptionally wide (34-41 nm thick), which provides space to accommodate electron-rich molecules.Electron-deprived structures are located in the cytosol and are believed to be glycogen storage vesicles; polyhydroxybutyrate and polyphosphate granules are also identified in the cytoplasm.
