Bacillus subtilis natto supernatant inhibits E. faecalis autoaggregation. (A) Macroscopic analysis of untreated (control) and B. subtilis natto supernatant-treated (10 and 50% v/v) E. faecalis cultures after 24h of cultivation. (B) Percentage autoaggregation exhibited by untreated (control) and B. subtilis natto supernatant-treated (10 and 50% v/v) E. faecalis. The data are presented as the means±SDs (n=3). Values with asterisks (*) were significantly different compared with the negative control (untreated) group according to Duncan’s multiple range tests (*p<0.05; **p<0.01). (C) SEM images of E. faecalis aggregates.
