Figure 5. Pyocyanin binding with DNA responsible for thick slimy EPS formation.

Figure 5

Photographic image showing formation of bacterial pellet and thick slimy eDNA constituted EPS (only on wildtype strain) formation after harvesting and centrifugation of 3 day old planktonic culture of P. aeruginosa PA14 strains (above panel). The slimy eDNA constituted EPS degraded completely after DNase I treatment in wildtype strain where as the pyocyanin deficient mutant ΔphzA-G does not show any effect on DNase I treatment (below panel).
