Strain C7258ΔlacZ containing plasmid pHapRLac2 was grown overnight in LB at 37°C. On the next morning the culture was diluted in fresh LB (□) or LB containing 0.2% glucose (■) and samples taken at different times to determine the expression of β-galactosidase activity. Each point is the average of three independent experiments.
