FIG 5.
Extracellular virulence factor production by P. aeruginosa from 12-, 18-, 24-, and 30-h cell-free culture supernatants treated with OligoG CF-5/20 (0.2, 2, or 10%). Panels: A, pyocyanin; B, rhamnolipids; C, total protease; D, elastase. The average from four replicates ± the standard deviation is shown. *, P < 0.05. Differences in culture biomass (at ≥2% OligoG CF-5/20) were corrected according to dry weight.
