Experimental evolution of Escherichia coli on semi-dry silver, copper, stainless steel, and glass surfaces
M. Rosenberg, S. Park, S. Umerov, A. Ivask
This study shows Escherichia coli evolves increased tolerance to copper and silver surfaces without enhanced metal ion resistance or mutation accumulation, suggesting passive metal restriction mechanisms are favored over active efflux.
