The structure of Aerobacter aerogenes capsular polysaccharide.

The biosynthesis of capsular polysaccharide in Aerobacter aerogenes.

The Distribution of Polysaccharide Production in Aerobacter and Escherichia Strains and its relation to Antigenic Character

Strains of Aerobacter aerogenes, A. cloacae and Escherichia coli, including mucoid capsulate, mucoid non-capsulate, smooth and rough variant forms, were grown on defined agar media. The polysaccharide content of the cultures was estimated by the anthrone method and related to the amount of growth as measured by the non-dialysable nitrogen content. Polysaccharide production, as measured by the p...

Isolation and characterization of a bacteriophage polysaccharide.

A high molecular weight heteropolysaccharide, composed of glucose, glucuronic acid, N-acetylglucosamine, and mannose in an approximate molar ratio of 1:2:2:5, respectively, was isolated from phage K-2 and from the soluble fraction of phage-infected Aerobacter aerogenes lysates. Treatment of pure phage with 8 M urea at 4 degrees quantitatively solubilizes the bound polysaccharide and capsular po...

Expression of E.coli capsular polysaccharide requires the KfiB protein:A Structural based analysis

Abstract Background and objectives: important virulence factor for many invasive bacterial pathogens of humans. Escherichia coli offer a model system to study the mechanisms by which capsular polysaccharides are synthesized and exported onto the cell surface of bacteria. Biosynthesis of the E consists of the repeat structure -4) GlcA- (1, 4)-GlcNAc- (1-, requires the KfiA,...

The depolymerization of bacterial polysaccharides by hyalyronidase preparations.

It has been demonstrated that some strains of Aerobacter aerogenes and Achromobacter fischeri synthesized relatively large amounts of a mucopolysaccharide which was depolymerized by hyaluronidase (Warren, 1950, 1951). This synthesis is of special interest because the bacterial mucopolysaccharide (hyaluronic acid) depolymerized by hyaluronidase has been generally assumed to be limited to the cap...
