title: Pseudomonas aeruginosa Psl is a galactose- and mannose-rich exopolysaccharide.
abstract: The Pseudomonas aeruginosa polysaccharide synthesis locus (psl) is predicted to encode an exopolysaccharide which is critical for biofilm formation. Here we used chemical composition analyses and mannose- or galactose-specific lectin staining, followed by confocal laser scanning microscopy and electron microscopy, to show that Psl is a galactose-rich and mannose-rich exopolysaccharide.
