The Pseudomonas aeruginosa lectin LecB binds to the exopolysaccharide Psl and stabilizes the biofilm matrix

Abstract

Pseudomonas aeruginosa biofilms are composed of exopolysaccharides, exogenous DNA, and proteins. Here, da Silva et al show that protein LecB binds to matrix exopolysaccharide Psl, thus contributing to increased retention of bacterial cells and exopolysaccharide in growing biofilms.
