Effect of <i>fur</i> mutation on biofilm formation in <i>Pcb</i>1692.

<p>A. Qualitative biofilm formation showing biofilms in conical flasks after crystal violet staining. Flask A, B, and C represents <i>Pcb</i>1692 wild-type, <i>Pcb1692</i>Δ<i>fur</i> mutant strain, and <i>Pcb1692</i>Δ<i>fur</i>-p<i>fur</i> strain respectively. B. Quantitative biofilm formation by <i>Pcb</i>1692 wild-type, <i>Pcb1692</i>Δ<i>fur</i> mutant and <i>Pcb1692</i>Δ<i>fur</i>-p<i>fur</i> complement strain<b>.</b> Standard deviation and averaged mean values represent optical densities (OD₅₇₀) from three independent experiments. Statistically significant difference were determined by the one way ANOVA and <i>p</i>-values less than 0.05 (<i>p</i><0.05) were considered to be statistically significant.
