Figure 1. Pyocyanin production in P. aeruginosa PA14 strains and effect of DNase I treatment in PA14 aggregation.

Figure 1

(A) Shows production of pyocyanin in planktonic culture of PA14 DKN370 and wildtype (indicated by green colour) and lack of pyocyanin production in ΔphzA-G strain even over 3 days growth period. (B) Represents an example of raw data showing decrease in absorbance at 600 nm OD due to aggregation of PA14 DKN370, wildtype and ΔphzA-G over 60 minutes. DKN370: before DNase I treatment (closed square), after DNase I treatment (open square), wildtype: before DNase I treatment (closed circle), after DNase I treatment (open circle), ΔphzA-G: before DNase I treatment (closed triangle), after DNase I treatment (open triangle).
