Abstract
Kinetics of thymineless death for Escherichia coli 15 TAU-bar from plating on solid medium were compared with those from direct observations of single cells under a microscope. The latter method did not involve any physical change of the medium. The kinetics obtained for the two methods were identical. This rules out the assumption that in E. coli 15 TAU-bar death from the thymine deprivation is directly associated with the plating procedure.
摘要
对大肠杆菌15 TAU-bar在固体培养基上进行平板接种后的无胸腺嘧啶死亡动力学，与在显微镜下对单个细胞进行直接观察所得到的动力学进行了比较。后一种方法不涉及培养基的任何物理变化。两种方法所获得的动力学是相同的。这排除了关于在大肠杆菌15 TAU-bar中，胸腺嘧啶剥夺导致的死亡与平板接种程序直接相关的假设。
