WebpH of the periplasm and that are the subject of this study are indicated in Figure 1. Figure 1. Scheme of the cell compartments of the Gram negative bacterium At. The periplasm is a concentrated gel-like matrix in the space between the inner cytoplasmic membrane and the bacterial outer membrane called the periplasmic space in gram-negative bacteria. Using cryo-electron microscopy it has been found that a much smaller periplasmic space is also present in gram-positive bacteria.
