In a strain deleted for the regulator NtrC growth rate declines gradually. E. coli Δ ntrC was grown in M9 minimal medium with the indicated concentrations of nitrogen (in the form of NH4Cl). OD (600 nm) was measured at a time resolutions of 3 min. Each point in the graph represents the average OD of 48 experimental replicates.
