Growth curves of PA wild type (WT) (PAO1) in M9 minimal medium with different carbon sources. Conditions evaluated were M9 medium supplemented with (A) 0.2% N-acetyl glucosamine (GlcNAc), (B) 0.2% glucose, (C) 0.2% N-acetyl chitobiose (GlcNAc)2, (D) 0.2% N-acetyl galactosamine (GalNAc), (E) 0.2% galactosamine (GalN), and (F) water. The data are represented as the mean of four biological experiments, the black line, with the SD shown as the red area of the mean.
