Abstract
Radiation damage to K+ permeability of an unsaturated fatty acid auxotroph of E. coli grown with oleate or linolenate was investigated at different temperatures. A remarkable effect of radiation was observed at 0 degrees C with cells that had been grown with linolenate at 42 degrees C. This indicates that, besides protein, membrane lipids at least are involved in the radiation damage. The damage also seems to be affected by the fluidity of membrane lipids.
摘要
研究了在不同温度下，辐射对以油酸或亚麻酸生长的大肠杆菌不饱和脂肪酸营养缺陷型钾离子通透性的损伤。在0摄氏度时，观察到用亚麻酸在42摄氏度下培养的细胞受到辐射有显著影响。这表明，除蛋白质外，至少膜脂也参与了辐射损伤。损伤似乎也受膜脂流动性的影响。
