Effects of Dps on biofilm formation. Wild-type strain NCTC11168 (solid bars), the NCTC11168 Δdps mutant (bars with vertical lines), and complemented NCTC11168 Δdps(pJRT101) (bars with horizontal lines) were assayed for ability to form biofilms, as described in Materials and Methods. Each sample was run in triplicate. Error bars indicate 1 standard deviation. A one-way ANOVA was done using OpenEpi software (version 2.3.1) to determine differences in biofilm formation. A significant difference in biofilm formation between the wild-type NCTC11168 strain and dps mutants was observed at all time points (P < 0.0001).
