Biofilm formation assay of wild-type (WT) and mutant (△abaI) strains. A and B Image of the biofilm of WT and △abaI strains stained using CV staining in a 96-well plate after 24-h incubation at 37℃ (original magnification × 40). C Absorbance of CV solution at 550 nm between WT and △abaI strains. Six individual biological replicates were performed in quadruplicates, and the data were represented as the means ± standard deviation of the results. ^*P < 0.05
