Imaging bacterial polysaccharides by AFM [PDF]
Polymer Bulletin, 1995 Atomic force microscopy has been used to image the bacterial polysaccharides xanthan, acetan and gellan. Images were obtained under constant force conditions in a liquid cell. Drops of dilute solutions of the polysaccharides were deposited onto freshly cleaved surfaces of mica and allowed to dry in air.

Bacterial Polysaccharide Capsules
2010A common feature of many bacteria is the expression of a layer of extracellular polysaccharide usually organised into a discrete structure termed the capsule. The expression of a capsule results in the coating of the bacterium in a hydrated shell of high molecular weight polysaccharide molecules that mediate interactions between the bacterial cell and ...

1983
Publisher Summary This chapter discusses bacterial polysaccharides. The bacterial polysaccharides make up a group of polymers in which the structural variation is almost unlimited, and unusual sugars are often the components of these polymers. Some bacterial polysaccharides are commercially important and produced industrially.

Pharmacology of pyrogenic bacterial polysaccharides
Bulletin of Experimental Biology and Medicine, 1957Certain aspects of the pharmacodynamics of bacterial pyrogenic polysaccharides were studied in this work. It was established that there is an increase of the body temperature in animals, which lasts for 6–7 hours, following parenteral administration of this preparation in the dose from 1γ per kilogram and over.

Bacterial Polysaccharides, Endotoxins, and Immunomodulation
1992These studies show that at least some--though certainly not all--of the adjuvant effects of LPS and its derivatives can be attributed to its ability to eliminate the inhibitory effects of Ts which are activated during the course of a normal immune response.

Biopolymers, 1978
AbstractThe optical activity of the Klebsiella capsular polysaccharides of serotypes K1, K5, K6, K8, K11, K56, and K57 has been studied in aqueous solution. Measurements of ORD in the range 185–450 nm reveal anomalous ORD with Cotton effects near λ0 = 195nm. The results are evaluated quantitatively according to hte Moffitt‐Yang and the Drude equations.

Immunology of bacterial polysaccharide antigens
Carbohydrate Research, 2003Carbohydrates 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, 1993J.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.
