From: Alginate oligosaccharides enhance diffusion and activity of colistin in a mucin-rich environment
Analysis of planktonic (supernatant) and biofilm growing cells of 24 h P. aeruginosa NH57388A, following 24 h treatment with colistin ± 1% OligoG added onto the artificial sputum medium surface (± SD; n = 5). (a) Planktonic bacteria from the biofilm supernatant. (b) Planktonic bacteria after biofilm washing. (c) Total planktonic bacteria (a + b). (d) Attached biofilm bacterial population. Significant difference is indicated by *, where *p < 0.05 compared to untreated control and #p < 0.05 between two groups as indicated by horizontal bar.
