Characterization of eDNA from the Clinical Strain Acinetobacter baumannii AIIMS 7 and Its Role in Biofilm Formation

Figure 6

Quantitative biofilm assays for A. baumannii AIIMS 7. Representative graphs showing biofilm augmentation after external supplementation with (a): purified eDNA (178.83% augmentation); (b): purified genomic DNA (170.79% augmentation); (c): purified membrane vesicle suspension (170.11% augmentation); (e): whole cell lysate (167.89% augmentation); (d): biofilm augmentation seen after replacing Luria broth with cell-free supernatant (CFS; 211.19% augmentation) and supplementation with 15× CFS (224.64% augmentation) (f): Effect of DNase I treatment on preformed biofilms. (59.41% reduction).
