Fig. 7From: The MarR family regulator OsbR controls oxidative stress response, anaerobic nitrate respiration, and biofilm formation in Chromobacterium violaceumOsbR affects C. violaceum growth under anaerobic conditions. The indicated strains of C. violaceum were diluted to OD600 = 0.1 in LB medium or LB plus 0.5% NaNO3. The cultures were grown without agitation in an anaerobic jar and the OD600 was measured after 48 h. Statistical analysis was performed by Two-way ANOVA and P value < 0.05 was considered significant. P value < 0.05 = *; P value < 0.01 = **; P value < 0.001 = ***; P value < 0.0001 = ****Back to article page
