From: Effect on β-galactosidase synthesis and burden on growth of osmotic stress in Escherichia coli
Effect of NaCl concentration on the growth of ∆lacI and ∆lacIlacZ E.coli at a fixed glycerol concentration of 1 g/L. a. Specific growth rate at various NaCl concentrations. Filled and Open Square, respectively, represents the growth rate for ∆lacIlacZ and ∆lacI at various salt concentrations. Solid and dashed line represents Hill equation fit for growth rate. b. Burden or ф at various salt concentrations. Filled and Open Square respectively, represents the ф for ∆lacIlacZ and ∆lacI. c. β-galactosidase synthesis and activity at various salt concentrations. Filled Square represents synthesis and activity while open square represents only activity.
