Conformational investigation on the bacterial polysaccharide xanthan
Carbohydrate Research, 1979The conformation of xanthan has been investigated as a function of temperature, ionic strength, and polymer concentration. A reversible transition induced by temperature is demonstrated; the melting temperature (TM) is directly correlated to the total ionic-strength and is independent of the polymer concentration.

Capillary Electrophoresis of Bacterial (Lipo)Polysaccharides [PDF]
, 2010 Lipopolysaccharides (LPSs) are major components of the outer membrane of gram-negative bacteria, and, along with some acidic polysaccharides, are important macromolecules belonging to bacteria. The recent emergence of modern analytical tools for their study has produced a virtual explosion in the field of glycomics.

Involvement of Bacterial Polysaccharides in Plant Pathogens
Annual Review of Phytopathology, 1995Virulence of phytopathogenic bacteria is often correlated with their ability to produce extraceUular polysaccharides (EPSs). The composition and amount of lipopolysaccharide O-antigens and low molecular weight, cell-associated 13linked glucans may also affect virulence of Gram-negative pathogens. For a few species of Agrobacterium. Clavibacter, Erwinia.

Bacterial Polysaccharide Vaccines
2011Capsulated bacteria, Gram-positive or Gram-negative, cause a variety of infections in man. Prominent among them are streptococci of Lancefield’s groups A, B, and C, staphylococci, meningococci, Haemophilus influenzae type b, klebsiellas, Escherichia coli, and Salmonella typhi, to name but some.

Visualization of the Bacterial Polysaccharide Capsule
1990The highly hydrated capsule of E. coli strains is composed of a large number of polysaccharide fibers of which the thinnest measure about 2 nm in width. The fibers may span the entire distance from the outer membrane to the outer rim of the capsule and show a propensity to associate with each other to form thicker filaments. Presence of thick filaments

Bacterial capsular polysaccharides and exopolysaccharides
2010Bacteria often produce an external layer of polysaccharides, characterized by a definite primary structure, which in turn is responsible for sometimes remarkable physicochemical properties. Although the number of monosaccharides which constitute the polymers is rather low, the great number of different polysaccharides defined up to now shows the ...

Degradation of polysaccharides by intestinal bacterial enzymes
The American Journal of Clinical Nutrition, 1978Polysaccharides with structures resembling components of dietary fiber were fermented by a number of species of anaerobic bacteria from the human colon. Some strains also fermented glycoprotein mucins. The strains that fermented the widest range of polysaccharide substrates were in the two genera Bacteroides and Bifidobacterium.

Bacterial Capsular Polysaccharide and Sugar Transferases
2004Capsular polysaccharides (CPs) of several pathogenic bacteria are thought to be good materials for the development of new therapeutic reagents. These polysaccharides can be used as vaccines against infection of pathogenic bacteria and are also useful as inhibitors for disease caused by aberrant and abnormal cell-cell interaction, such as cancer ...

Bacterial polysaccharide synthesis and gene nomenclature
Trends in Microbiology, 1996Gene nomenclature for bacterial surface polysaccharides is complicated by the large number of structures and genes. We propose a scheme applicable to all species that distinguishes different classes of genes, provides a single name for all genes of a given function and greatly facilitates comparative studies.
