In the Cairns-Foster adaptive mutation system, lac mutant cells are plated on lactose medium where 50 revertant colonies accumulate over 5 days above a non-growing lawn. A new model attributes this behavior to selective... The Escherichia coli system

The Escherichia coli system of Cairns and Foster employs a lac frameshift mutation that reverts rarely (10(−9)/cell/division) during unrestricted growth. However, when 10(8) cells are plated on lactose medium, the nongrowing lawn produces ∼50 Lac

To test whether growth limitation induces mutations, Cairns and Foster constructed an Escherichia coli strain whose mutant lac allele provides 1–2% of normal ability to use lactose. This strain cannot grow on lactose, but produces ∼50 Lac+ revert
