Impact of glycine and glycine/ZnO nanocomposites on the growth of P. aeruginosa by measuring optical density (OD) at 600 nm. Bacterial growth curve was generated using various concentrations: (a) 50 µg/mL, (b) 100 µg/mL, (c) 300 µg/mL, and (d) 500 µg/mL. Bacteria were treated with a positive control of 100 µg/mL kanamycin and a negative control by incubating in (MHB). The OD measurements represent the mean values from three independent experiments, each performed in triplicate.
