MIeJ Diauxie Revisited: The Case of Fructose

FIGURE 4: Growth and β-galactosidase activity of isogenic fruR and fruR crr strains

A: Fructose plus lactose
Figure 4-A
Strains (fruR) were grown in 1.5 mM fructose and 5 mM lactose minimal medium at 37 °C
Gray open square: growth curve, black open triangle: β-galactosidase

B: Fructose plus lactose plus cAMP
Figure 4-B
Strains (fruR crr) were grown in 1.5 mM fructose and 5 mM lactose minimal medium at 37 °C
Gray open square: growth curve, black open triangle: β-galactosidase
