Evolutionary adaptation to freeze-thaw-growth cycles in Escherichia coli.

Physiological and biochemical zoology : PBZ - 1 Jan 2000

Sleight Sean C, Lenski Richard E

Abstract excerpt

Fifteen populations of Escherichia coli were propagated for 150 freeze-thaw-growth (FTG) cycles in order to study the phenotypic and genetic changes that evolve under these stressful conditions. Here we present the phenotypic differences between the evolved lines and their progenitors as measured by competition experiments and growth curves. Three FTG lines evolved from an ancestral strain that was previously...
