The Influence of Lipopolysaccharide O-Antigen Chain Length on Biofilm Formation Capacity and Outer Membrane Proteome Shape of Salmonella Enteritidis.

ABSTRACT: Biofilm formation is a phenomenon of great medical importance, also affecting food production. In the present work, we investigated the effect of the O-antigen length of lipopolysaccharide (LPS) of Salmonella Enteritidis on biofilm production and the physicochemical properties of Salmonella cells, using bacterial deletion mutants. We also analysed the influence of LPS O-antigen shortening on the composition of the outer membrane (OM) proteome of S. Enteritidis. We have shown that the shortening of the LPS O-antigen part is associated with decreased biofilm biomass formation in some mutants and that it also depends on the composition of the culture medium. Physicochemical properties of bacterial cells changed with the shortening of the O-antigen, promoting bacterial aggregation and influenc
