external face of the peptidoglycan sacculus and forms a robust permeability barrier that …

Walls and membranes in bacteria

DA Reaveley, RE Burge - Advances in microbial physiology, 1972 - Elsevier
Publisher Summary Cohn suggested that the resistance of bacteria to attack by acids and
alkalies was because of the presence of a rigid structure surrounding the cell. The …

How bacterial cell division might cheat turgor pressure–a unified mechanism of septal division in Gram‐positive and Gram‐negative bacteria

HP Erickson - Bioessays, 2017 - Wiley Online Library
An important question for bacterial cell division is how the invaginating septum can
overcome the turgor force generated by the high osmolarity of the cytoplasm. I suggest that it …
