Quantitative biofilm formation by A. baumannii ATCC 17978, Δata, and Δata-c on polystyrene surfaces. A. baumannii 17978 and Δata were grown in LB and ATCC 17978 Δata-c in LB plus 2% arabinose or 0.2% glucose under static conditions for 24 h at 37°C. Total biofilm formation (OD₅₉₅) was normalized by bacterial growth (OD₆₅₀). The bars indicate the means of 15 tubes from five independent experiments ± SEM. P values were determined by one-way ANOVA with Tukey's post hoc analysis. ns, not significant.
