Growth of ΔaauR, rpoN::Ω-Km, ΔaatJ and ΔaatQM mutants of P. aeruginosa PAO1 on L-glutamate (a), L-glutamine (b), L-aspartate (c) and L-asparagine (d) as nitrogen sources. Bacteria were grown at 37 °C in minimal media supplemented with 20 mM glucose and 10 mM of indicated amino acid as the sole nitrogen source. Data points represent mean values (n = 3) ± SD
