Antimicrobial activity of C7 (left panel) and C9 (right panel). (A)Visual growth of different bacterial and fungal strains. Bacteria were cultured in an LB medium and fungi were cultured in a PDA medium at 25 °C in a dark state. The medium was treated with C7 and C9 at concentrations of 0 ppm, 100 ppm, 500 ppm and 1000 ppm, respectively. Colonies were observed after 1 and 2 weeks of growth after inoculation. (B) Colony diameter according to the concentration of the compounds at 1 week and 2 weeks after inoculation. Means with the same letters are not significantly different by Duncan’s multiple range test at p < 0.05.
