Minimum bactericidal concentration (MBC) of the rGO-Cu-Ag composite. Growth of X. euvesicatoria treated with different rGO-Cu-Ag concentrations (shown above each plate) in comparison with the nontreated control (A). SEM images of X. euvesicatoria cells untreated (B) and treated with 50 µg mL−1 (C) and 500 µg∙mL−1 rGO-Cu-Ag (D). Samples of total DNA extracted from the X. euvesicatoria NCPPB 2968 samples after cultivation with different concentrations of the rGO-Cu-Ag nanocomposite. The positive control sample without nanocomposite treatment is represented by lane 1. Lanes 2 to 5 represent nanocomposite concentrations of 6.25, 12.5, 25.0 and 50.0 µg mL−1, respectively. Lane 6 represents 100 kb ladder (E)
