Fig. 1From: The MarR family regulator OsbR controls oxidative stress response, anaerobic nitrate respiration, and biofilm formation in Chromobacterium violaceumConstruction and analyses of C. violaceum strains with deletion (∆osbR) or overexpression (WT(osbR)) of osbR. a The levels of OsbR in the indicated strains were analyzed by western blot using a polyclonal anti-OsbR antiserum. Equal protein loading was confirmed by Ponceau staining. Full-length blot and Ponceau-stained membrane are presented in Additional file 3, Fig. S3. b Growth curves of the indicated strains in LB medium. All strains showed a similar growth profileBack to article page
