Abstract excerpt
When Escherichia coli FC40 formed adaptive Lac+ revertants on a selective agar medium containing lactose as the carbon source, the colonies which accumulated over several days were of two readily distinguishable types. Colonies of both types appeared both early and late on the plates. Cells of co...
