Role of polysaccharides in Pseudomonas aeruginosa biofilm development

Abstract

During the past decade, there has been a renewed interest in using Pseudomonas aeruginosa as a model system for biofilm development and pathogenesis. Since the biofilm matrix represents a crucial interface between the bacterium and the host or its environment, considerable effort has been expended to acquire a more complete understanding of the matrix composition. Here, we focus on recent developments regarding the roles of alginate, Psl, and Pel polysaccharides in the biofilm matrix. © 2007 Elsevier Ltd. All rights reserved.
