The size of Escherichia coli and Salmonella enteritidis PT4 cells was measured using both transmission electron micrographs and image analysis. Incubation in the presence of formic and propionic acids resulted in larger cells, possibly as a result of DNA inhibition, with no apparent damage to the cell membranes. Bacteria incubated with propionic acid were more resistant to shrinkage after fixation, possibly as a result of altered phospholipid and fatty acid composition.
利用透射电子显微镜照片和图像分析测量了大肠杆菌和肠炎沙门氏菌PT4细胞的大小。在甲酸和丙酸存在的情况下进行培养会导致细胞变大，这可能是DNA受到抑制的结果，而细胞膜没有明显损伤。用丙酸培养的细菌在固定后对收缩更具抗性，这可能是磷脂和脂肪酸组成发生改变的结果。
