Population dynamics of a Lac- strain of Escherichia coli during selection for lactose utilization.

Genetics - 1 Oct 1994

Foster P L

Abstract excerpt

During selection for lactose utilization, Lac+ revertants of FC40, a Lac- strain of Escherichia coli, appear at a high rate. Yet, no Lac+ revertants appear in the absence of lactose, or in its presence if the cells have another, unfulfilled requirement for growth. This study investigates more fully the population dynamics of FC40 when incubated in the absence of a carbon source or when undergoing selection for...
