The quantity of biomass at each stage of biofilm formation of the S. epidermidis. The tested strains were incubated for 6, 24 and 48 h to form adhesion, aggregation and maturity stage of biofilms respectively, and treated with BB and mupirocin, followed by the biofilms being stained with crystal violet, and quantified. (A) SE04 treated for 6 h; (B) SE04 treated for 24 h; (C) SE04 treated for 48 h; (D) SE08 treated for 6 h; (E) SE08 treated for 24 h; (F) SE08 treated for 48 h. Compared with the control group, ** means P < 0.01, **** means P < 0.0001; Compared with the BB group, # means P < 0.05, ## means P < 0.01, ### means P < 0.001; Compared with the mupirocin group, + means P < 0.05, +  + means P < 0.01, +  +  + means P < 0.001, +  +  +  + means P < 0.0001
