Over-expression of RpoD suppresses mucoidy in laboratory and clinical strains of P. aeruginosa.

NM and M represent non-mucoidy and mucoidy, respectively, after incubation on PIA plates supplemented with 300 µg/ml of carbenicillin and 0.1% L-Ara at 37°C for 24 hrs.aa concentration of 0.5% L-Ara was needed to completely suppress mucoidy. The values for alginate production represent an average of three independent experiments with standard error.
