The role of YB on HIa expression of S. aureus strain pALC1740.GFP fluorescence intensity was used to indicate HIa expression in YB-treated pALC1740. (A) hla promoter activity was evaluated by GFP-mediated fluorescence in YB-treated pALC1740. (B) Overall fluorescence intensity in YB-treated pALC1740. (C) Fluorescence intensity of the largest biofilm in YB-treated pALC1740. (D) The area of the largest biofilm in YB-treated pALC1740. WL: White light.
