Fig. 2From: Serratiopeptidase: a well-known metalloprotease with a new non-proteolytic activity against S. aureus biofilmBiofilm formation of S. aureus 6538P in the presence of supernatant deriving from E. coli BL21DE3 harboring pET28b-Spep and pET28b-Spep-EmutA, respectively. Biofilm was reported as absorbance at 590 nm after crystal violet coloration. Results are representative of four independent experimentsBack to article page
