The metabolic activity of the bacteria at each stage of the formation of S. epidermidis biofilm. 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 treated with XTT solution, 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 < 0.05, ** means P < 0.01, *** means P < 0.001, **** means P < 0.0001; Compared with the BB group, # means P < 0.05, #### means P < 0.0001; Compared with the mupirocin group, + means P < 0.05, +  +  +  + means P < 0.0001
