Inhibitory effect of B. subtilis natto supernatant on E. faecalis biofilm polysaccharide production. E. faecalis OG1RF was anaerobically cultured in M9B broth without or with B. subtilis natto supernatant (0, 10, and 50% v/v) for 24 or 48h. The polysaccharide contents obtained from E. faecalis biofilms were determined using the PSA method. The data are presented as the means±SDs (n=3). Values with asterisks (*) were significantly different compared with each negative control group according to Duncan’s multiple range tests (^*p<0.05).
