Glucose resensitization mechanism is independent of growth resumption. Stationary-phase cultures were washed with, resuspended in, and further incubated in saline for 1 h before addition of water (A), 10 mM glucose (B), 9.5 mM NH₄Cl (C), 1.32 mM K₂HPO₄ (D), or 0.286 mM MgSO₄ (E). Concentrations were based on those found in minimal M9 medium (53). Following treatments, cultures were incubated for 7 h and CFUs were determined at the indicated time points. *, P < 0.05 (t test), comparing glucose with glucose plus NIT. Data represent at least three biological replicates. Each data point was denoted as mean ± SE.
