Abstract
The peptidoglycan compositions of three isogenic morphological mutants of Escherichia coli were determined by high-pressure liquid chromatography analysis. The muropeptide compositions of the peptidoglycan of these mutants were the same, indicating that the shape of E. coli is not (solely) determined by the chemical composition of the peptidoglycan. Furthermore, it appeared that the muropeptide composition of the peptidoglycan was not affected by growth temperature.
摘要
通过高压液相色谱分析确定了大肠杆菌三个同基因形态突变体的肽聚糖组成。这些突变体肽聚糖的胞壁肽组成相同，这表明大肠杆菌的形状并非（仅仅）由肽聚糖的化学组成决定。此外，似乎肽聚糖的胞壁肽组成不受生长温度的影响。
