Biofilm formation influenced by compounds 9, 10, 11, 12, and 14 in Aeromonas caviae Sch3 at 6 × 10⁸ colony forming units (CFU)/mL bacteria. The data are presented as percentages of the biofilm formation of the control, which received no inhibitor treatment and was set as 100%. The compounds were evaluated at 100, 10, and 1 µM concentrations. Dimethyl sulfoxide (DMSO) had no significant effect on biofilm formation; the control experiment data can be found in the Supplementary Materials. Significance was confirmed by the Student’s t-test with an accuracy of * p < 0.005 and ^# p < 0.05 at the marked bars. Experiments were performed with n = 6. Compound number (Cpd No.)
