WebPeptidoglycan is a rigid envelope surrounding the cytoplasmic membrane of most bacterial species. It helps protect bacterial cells from environmental stress and helps preserve cell morphology throughout their life cycle. Peptidoglycan biosynthesis is also an important regulator of bacterial cell division. Since the discovery of penicillin, it ... WebApr 3, 2013 · For a detailed review of peptidoglycan structure and architecture, I refer readers to an excellent review by Vollmer et al. (2008). Bacterial cell division by binary fission requires the growth of the peptidoglycan cell wall as the bacterium elongates (Amir and Nelson, 2012). In rod-shaped bacteria, the cell wall grows at multiple locations ...
