Acetate salt stimulates biofilm formation in S. aureus. (A) Formation of submerged, surface-attached biofilms by S. aureus HG003 in TSB supplemented with 1% glucose in the absence or presence of 0.2%, 0.5%, and 1% NaAc. A concentration of 1% is defined as 10 g of NaAc in 1 liter of medium. Biofilms attached to the bottom of the 24-well polyvinyl plate (VWR) were visualized by crystal violet staining. (B) Results of a semiquantitative measurement to compare the biomasses of the surface-attached biofilms described for panel A. AU, absorbance units.
