Specific solute effects on Staphylococcus aureus cells subjected to reduced water activity
The behaviour of Staphylococcus aureus cells subjected to lowered water activity (aw) by the addition of various solutes was examined by transmission electron microscopy. Solutes included sodium chloride, sucrose, propylene glycol, butylene glycol and various polyethylene glycols. Changes in other p...
