Fig. 8From: The MarR family regulator OsbR controls oxidative stress response, anaerobic nitrate respiration, and biofilm formation in Chromobacterium violaceumOsbR represses biofilm formation in C. violaceum. Strains were diluted to OD600 = 0.01 in LB medium, and the biofilm formation was measured after growth in static condition for 24 h. Upper: Representative test tubes for each strain after biofilm staining with violet crystal. Bottom: Quantification of biofilm formation by measurement of OD600. Statistical analysis was performed with One-way ANOVA with P value < 0.05 being considered significant. ****, P value < 0.0001Back to article page
