Change of optical density of Cutibacterium acnes KCTC 3314 culture by concentrated supernatants of cell lysates of recombinant Escherichia coli BL21(DE3) strains. (A) Optical densities during incubation time; (B) Transparency of cell culture in wells. Control, lysis buffer; pET-15b, E. coli BL21(DE3) (pET-15b); pET-15b_CAP10-3 end, E. coli BL21(DE3) (pET-15b_CAP10-3 end). The experiment was repeated 3 times and expressed as mean ± standard deviation.
