Figure 6. Norspermidine inhibits biofilm formation by S. aureus.

Figure 6

Panel A shows the effect of the numbered compounds displayed in Figure 5A on the formation of submerged biofilms by S. aureus strain SCO1. The compounds were tested at 500 µM. Biofilm formation was visualized by crystal violet staining of submerged biofilms. Panel B shows quantification of the effects of norspermidine, norspermine, spermine and spermidine as measured by crystal violet staining (see Experimental procedures). See also Figure S6.
