A. Total protein accumulation per CDW (filled squares), protein accumulation per CDW in the medium (circles) and cell lysis (protein in the medium/total protein, open squares) as a function of time. B. β-lactamase accumulation per CDW (filled squares), β-lactamase accumulation in the medium per CDW (circles) and leakage from periplasm to medium (β-lactamase in medium/total β-lactamase, open squares). The specific growth rate is indicated in the figure by a dashed line.
