Abstract

The fractions of Escherichia coli female and male bacteria that are competent to form specific mating pairs at any time during normal exponential growth have been measured by a physical assay. The competencies of a Hayes- and a Cavali-type donor were 35 and 50%, respectively, in agreement with piliation assays reported by others. The competencies of two recipient strains, PA309 and P678, were found to be 33 and 29%, respectively.

摘要

通过物理测定法测量了在正常指数生长期间任何时刻能够形成特定交配配对的大肠杆菌雌性和雄性细菌的比例。海斯型和卡瓦利型供体的感受态分别为35%和50%,这与其他人报道的菌毛测定结果一致。发现两个受体菌株PA309和P678的感受态分别为33%和29%。
