Method Electron microscopy
Comments Based on researchers' measurements, the periplasm occupies approximately 16% of the total cell volume and the separation between the inner and outer membranes is (45±10) nm. Electron microscopy images of the bacterial flagellar motor show that the separation between the outer membrane spanning L-ring component of the motor and the inner membrane spanning MS-ring is approximately 40 nm, in agreement with researchers' measurements [primary source].
