Summary Vibrio cholerae form biofilm, which is essential for their survival under harsh environmental conditions. The eDNA produced during biofilm formation and interaction with other components like vibrio polysaccharide is less studied in Vibrio cholerae despite its importance in biofilm structure and stability. In this study, we selected two strains of V . cholerae , which produced sufficient extracellular DNA in the biofilm, for characterization and studied its interaction with vibrio polysaccharide. Our data demonstrate that eDNA is present in the biofilm and interacts with VPS in V . cholerae . Our findings suggest that eDNA contributes to biofilm integrity by interacting with VPS and provides strength to the biofilm. Moreover, it might interact with other components of biofilm, which need further study.
