Figure 5From: Direct measurements of IPTG enable analysis of the induction behavior of E. coli in high cell density culturesComparison of the “pseudo-steady” states. A) Variation of the maximum specific RhuA activities (AU·g-1DCW) with the measured intracellular IPTG concentration (μM). B) Variation of the calculated intracellular inducer (μmol IPTG·g-1DCW) with the initial IPTG concentration (IPTG0, μM) added into the reactor. The analytical standard error for experimental IPTG measurements is 5 and 7% for medium and intracellular samples, respectively.Back to article page
