| Popis: | This study reports the extent and character of plasmolysis and other morphological changes as shown by electron microscopy in a strain of Klebsiella pneumoniae and with sucrose or polyethylene glycol 400 (PEG-400) as the plasmolysing agent at a water activity of 0.935. Both solutes produced severe plasmolysis in K. pneumoniae cells; PEG-400 also caused some cell wall collapse and fingerlike extrusions to emerge from the bacterial cell. |
