From: Carbon starvation of Pseudomonas aeruginosa biofilms selects for dispersal insensitive mutants
Complementation of non-dispersal phenotype of RSCV1 mutant under starvation conditions. Batch biofilms of WT, RSCV1, RSCV1/pBBR and RSCV1/pBBRwspF were cultivated for 6 h and starved. Biofilm biomass was quantified by crystal violet staining at different time points. Percentage biofilm changes were plotted against time and the rate of change of biofilm reduction was obtained through linear regression. Data shown are average values ± SD from 3 independent experiments. M9G-M9 medium containing glucose; M9S-M9 salts without carbon source. Asterisks indicate that the values are significantly different between strains (One-way ANOVA followed by Tukey’s post-test; * < P 0.05)
