Bacterial source tracking

Bacterial Source Tracking and Other Indicators of Fecal... 

When viewed in thin section under the electron microscope, the cytoplasmic membrane of bacterial cells has the same double-tracked profile as the unit membrane found in higher cells [10]. Sectioning reveals little detail of membrane structure apart from the thickness (70—80 A) which is similar to that of membranes from other sources. The major components of bacterial membranes are protein (50-70%) and phospholipid (20—30%), the proportions varying from organism to organism [11].
