ABSTRACT
Staphylococcus aureus cells grown in a defined medium under conditions of high ionic stress (2.5 M NaCl) were significantly larger than cells grown under unstressed conditions, even though the cells grew much more slowly under stressed conditions. Analysis of the structure of peptidoglycan from stressed cells showed a shorter interpeptide bridge than in peptidoglycan from unstressed cells. Glycine betaine inclusion in the high-NaCl medium resulted in cells with sizes and interpeptide bridges similar to those of cells grown under unstressed conditions.
