Figure 2

Effect of AKBA on the biofilm formation (A) and preformed biofilm (B) by S. aureus ATCC 29213 and S. epidermidis ATCC 12228. After incubation, the biofilms were stained with crystal violet and the optical density of stained adherent bacteria was determined with a multidetection microplate reader at a wavelength of 595 nm (OD595). The results are expressed as average optical density readings for crystal violet assays compared to growth control. The biofilm of S. aureus and S. epidermidis were significantly inhibited (A) and reduced (B) compared with those of bacteria without AKBA (P < 0.01). Values are mean (±SD) from four independent determinations. *, P < 0.01 (Student's t test).
