Conformational investigation on the bacterial polysaccharide xanthan

Carbohydrate Research, 1979
The 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.

Immunology of bacterial polysaccharide antigens

Carbohydrate Research, 2003
Carbohydrates in the form of capsular polysaccharides and/or lipopolysaccharides are the major components on the surface of bacteria. These molecules are important virulence factors in many bacteria isolated from infected persons. Immunity against these components confers protection against the disease.

Uptake of metals by bacterial polysaccharides

Journal of Applied Bacteriology, 1993
J.L. GEDDIE AND I.W. SUTHERLAND. 1993. The binding of cations by a range of bacterial polysaccharides was examined. Comparison of native and deacetylated polymers indicated the influence of polysaccharide acetylation on ion uptake and selectivity. The effects of temperature and pH on ion uptake were also examined.

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, 1995
Virulence 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.

Visualization of the Bacterial Polysaccharide Capsule

1990
The 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

2010
Bacteria 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, 1978
Polysaccharides 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 Polysaccharide Vaccines

2011
Capsulated 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.
