Growth of E. coli Knabc. Growth in liquid Medium: A) Growth curves of E. coli strains KNabc pUC18 (open Symbols, control) and KNabc pUCHelNhaD (black Symbols, NhaD) at 0% ¹⁾ (circles) and 3% (500 mM, squares) salinity (w/v) in MM63 minimal medium. Additionally growth data for XL1 Blue (WT, triangles) are shown for 0%. ¹⁾ Due to impurities of media components are still traces of NaCl (< 0.01%, 2 mM) in the medium.
