金黄色葡萄球菌细胞生长在高离子应力（2.5 M NaCl）条件下的确定的培养基中显着大于细胞生长在非应力条件下，即使细胞生长更缓慢的应力条件下。对来自应激细胞的肽聚糖的结构的分析表明，与来自未应激细胞的肽聚糖相比，肽间桥更短。甘氨酸甜菜碱列入高NaCl培养基中导致细胞的大小和肽间桥类似于那些在非应激条件下生长的细胞。
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 can 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.
