of D-glucuronic acid and differently sulfated residues of N-acetyl-D-galactosamine linked by β(1 >3) bonds (Volpi 2006a; Sugahara et al. 2003). Depending on the disaccha-ride nature, CS with different carbohydrate backbones are known. Chondroitin-4-sulfate, CSA, is constituted by 4-sulfated disaccharides ((1 >4] O (D-glucopyranosyluronic

The dermatan sulfate was present as the 4-sulfated isomer. Labeled proteoglycans were isolated from the growth media by centrifugation in either associative or disso-

Emulsifying behavior of an exopolysaccharide produced by

mers (e.g. polysaccharide protein surfactants), which are more effective at stabilizing oil-in-water emulsions (Rosenberg and Ron, 1999). A number of bioemulsifiers contain a polysaccharide moiety attached to lipid and/or protein. Emulsan is the only commercialized bacterial emulsifier obtained from

Enhanced Suppression of Tumor Growth by Combination of

polysulfonated trypan red derivative (14), a sulfated polysaccharide peptidoglycan complex extracted from an Arthrobacter species (15), and others (16†18)have been reported to inhibit angiogenesis and/or tumor growth. The development of solid tumors, however, is demarcated to 2 stages: the (a) prevascular and (b) vascular phases (1â

Pseudoalteromonas sp., Psychrobacter sp. and Arthrobacter sp. are the species that showed higher antibacterial activity. No antiviral activity was observed by polysaccharide extracts. The lack of knowledge and the preliminary results have led us to expand the research to other bacteria.

Dermatan sulfate is the predominant antithrombotic

The different species were highly purified and their anticoagulant and antithrombotic activities tested by in vitro and in vivo assays. We observed that dermatan sulfate is the major anticoagulant and antithrombotic among the vessel wall glycosaminoglycans while the bulk of heparan sulfate is a poorly sulfated

Heparan sulfate from PXE-affected indi-viduals and healthy carriers produced significantly less N-sulfated disaccharide and more disaccharide sulfated at the C-6 position with no significant abnormality of

diatom is composed of carboxylated or sulfated acidic polysaccharides. Diatom would secret mucilage strand at their central pore to tightly bind on the substrate (Cao et al., 2011). Diatom attachment would be prevent because when they are abundant, it can promote bio-corrosion of the surface (Silva-Aciares and Riquelme 2008).
