Bacterial Extracellular Polysaccharides

2011
Extracellular polysaccharides are as structurally and functionally diverse as the bacteria that synthesise them. They can be present in many forms, including cell-bound capsular polysaccharides, unbound "slime", and as O-antigen component of lipopolysaccharide, with an equally wide range of biological functions. These include resistance to desiccation,

Bacterial Polysaccharide Capsules

2010
A 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 ...

Bacterial extracellular polysaccharides

Canadian Journal of Microbiology, 1988
The synthesis of extracellular polysaccharides has been recognized in certain bacterial cultures since the 1880s. It is now apparent that a wide range of bacteria produce these polymers and an equally wide range of chemical structures are possible.

Conformational studies of bacterial polysaccharides. II. Optical activity of some bacterial capsular polysaccharides

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.
