    Abstract: There is disclosed a method for the manufacture of a crosslinked superabsorbent polymer material. There is further disclosed a crosslinked superabsorbent polymer material manufactured with the method. Using the new polymer material the previously used undesired chemistry based on polymerization of acrylamide is avoided and the less desired chemistry based on polymerization of on acrylic acid is significantly reduced. In addition the present polymer material is renewable. In contrast to the state of the art lignin does not have to be removed from the hydrolysate, so that energy, time and cost are saved and inexpensive raw materials and inexpensive process streams can be used. Lignin in the polymer material gives stronger bindings resulting in improved mechanical properties of the material. The presence of lignin further makes it possible to modify the hydrophilicity of the crosslinked polymer material. The raw materials are typically not valuable foodstuffs.

  • Patent number: 8609835
    Abstract: The present invention relates to purification and use of a novel emulsion stabilizing polysaccharide. In particular, a polyelectrolyte exopolysaccharide with high molecular weight comprising a high molecular weight polymer with a tri-saccharide repeating unit is disclosed. In one aspect of the invention, methods are directed to isolating and purifying a high molecular weight exopolysaccharide (EPS) from a cell supernatant. In another aspect, methods are disclosed for isolating a lipopolysaccharide (LPS) and a high molecular weight Acinetobacter polyelectrolyte exopolysaccharide (APE) from Acinetobacter bacteria. Compositions are also directed to lipid nanoparticles comprising a therapeutic agent encapsulated by a high molecular weight polysaccharide and nanoparticles comprising a therapeutic agent bound to a cationic polysaccharide cross-linked with a polyanion.

  • Patent number: 8604002
    Abstract: The invention provides an antifreeze glycolipid compounds and composition comprising a polysaccharide moiety of Formula I: wherein D-Manp represents a D-mannopyranose moiety, D-Xylp represents a D-xylopyranose moiety, and n is about 5 to about 70; and one or more lipid moieties covalently linked to the polysaccharide moiety of Formula I or electrostatically associated with the polysaccharide moiety of Formula I. The antifreeze glycolipid compounds and compositions can be used for a variety of industrial, agricultural, medical, and cosmetic applications where recrystallization-inhibition, cyroprotection, or cryopreservation is desired. The antifreeze glycolipid compounds or compositions can be used as, for example, as cryoprotectants for tissue preservation and transplantation, improving the texture of processed frozen food and frozen meats, frostbite protection, crop protection, and green alternatives for land vehicle antifreeze and aircraft de-icing.

  • Patent number: 8598337
    Abstract: This invention relates to improved methods for purifying polysaccharides from cellular components, such as a cell wall. The method relates to hydrolyzing and separating the polysaccharides, thereby resulting in purified polysaccharides useful for producing antigens, antibodies, and vaccines comprising the polysaccharides alone or conjugated to carrier molecules. This method is simple, rapid, efficient, scalable, and reproducible.
