Ligand 1Gal and complexes were tested for their ability to inhibit growth of P. aeruginosa (PAO1) at various concentrations. In brief: PAO1 was seeded into wells at 10 6 CFU/mL. Serial dilutions of each of the compounds then added to the wells and a set of control wells with no compound was also set up. Plates were incubated for 24 h at 37°C before absorption readings at 590 nm were taken. The Minimum Inhibitory Concentration (MIC) is defined as the lowest concentration of an antimicrobial agent that inhibits visible invitro growth of microorganisms. Each experiment was performed in four replicates.
