Figure 3From: Metabolic regulation of Escherichia coli and its gdhA, glnL, gltB, D mutants under different carbon and nitrogen limitations in the continuous cultureComparison of the transcriptional mRNA levels of the wild type E.coli genes cultivated at 100% (C/N = 1.68), 40% (C/N = 4.21), 20% (C/N = 8.42) and 10% (C/N = 1.68) N- concentration: (a) global regulatory, (b) N- regulatory, (c) metabolic pathway, (d) respiratory chain.Back to article page
