Figure 5

Overlay of regions of a representative 1D 1H NMR spectrum from the uninoculated BSF control (green), suspended culture (blue), and lawn biofilm (red) samples. Spectrum (a) shows zoomed in regions for metabolites with unique peaks in the 1D spectrum. Fumarate, ethanolamine, and gamma-aminobutyric acid are uniquely present in P. aeruginosa suspended and lawn biofilm cultures and absent in the uninoculated control. Beta-alanine was uniquely present in the 1D in the suspended culture. The brackets in spectrum (b) indicate three spectral regions containing NMR signals unique to the P. aeruginosa suspended and lawn biofilm cultures and void of signals from the uninoculated BSF control.
