  • Patent number: 6881838
    Abstract: Processes are disclosed for the purification and recovery of polysaccharide gums from an aqueous solution, particularly xanthan gum from a fermentation broth. An aqueous solution of at least one polysaccharide gum is mixed with a non-solvent stream comprising water and a subprecipitant level of a non-solvent of the polysaccharide gum. The mixture is concentrated to increase the polysaccharide gum concentration, and optionally undergoes a heat treatment. Additional non-solvent is added to the concentrated mixture to precipitate the polysaccharide gum. The precipitated gum is dried after being separated from the liquid component of the mixture. The removed liquid component can be recycled to the earlier step in the process in which the polysaccharide gum solution is mixed with the non-solvent stream.

  • Patent number: 6846917
    Abstract: Described is a modular, general synthetic strategy for the preparation in solution and on a solid support of heparin, heparin-like glycosaminoglycans, glycosaminoglycans and non-natural analogs of each of them. Additionally, the modular strategy provides the basis for the preparation of combinatorial libraries and parallel libraries of defined glycosaminoglycan oligosaccharides. The defined glycosaminoglycan structures may be used in high-throughput screening experiments to identify carbohydrate sequences that regulate a host of recognition and signal-transduction processes. The determination of specific sequences involved in receptor binding holds great promise for the development of molecular tools which will allow modulation of processes underlying viral entry, angiogenesis, kidney diseases and diseases of the central nervous system. Notably, the present invention enables the automated synthesis of glycosaminoglycans in much the same fashion that peptides and oligonucleotides are currently assembled.

  • Patent number: 6573375
    Abstract: Compositions comprising alkoxylated lipophilic polyol compounds, e.g., ethoxylated, esterified methyl glucosides, are disclosed wherein at least 5% of the polyol derivatives have about three moles of the lipophilic substituent per mole of polyol. Quite advantageously, the disclosed polyol derivatives can be dissolved into aqueous solutions to provide liquid thickeners suitable for thickening surfactant-containing compositions, e.g., shampoos, at cold processing temperatures.

  • Patent number: 6566516
    Abstract: A high purity polysaccharide containing hydrophobic group is produced by a process involving a first process step of producing an isocyanate group-containing hydrophobic compound, wherein one mole of a hydroxyl group-containing hydrocarbon having 12-50 carbon atoms or of a sterol is reacted with a diisocyanate represented by OCN—R1—NCO in which R1 is a hydrocarbyl of 1-50 carbon atoms, a second process step of producing the polysaccharide containing hydrophobic group composed of the hydrocarbon group of 12-50 carbon atoms or of the steryl group, wherein the isocyanate group-containing hydrophobic compound obtained in the first process step is reacted with one or more polysaccharides, and a purification step in which the reaction product in the second process step is purified using a solvent based on a ketone.

  • Patent number: 6562459
    Abstract: The invention relates to a method for the production of spherical microparticles consisting totally or partly of at least one water-insoluble polysaccharide, wherein the at least one water-insoluble polysaccharide is dissolved in a solvent or solvent mixture, the solution thus formed is introduced into a precipitating agent or precipitating agent mixture, the mixture obtained is optionally cooled and the formed microparticles are separated. The invention is characterized in that the water-insoluble polysaccharide is selected from a polyglucan containing branches with a degree of branching higher than zero and no higher than 8% and a mixture of a polyglucan containing branches and a linear polysaccharide, wherein the proportion of polyglucan containing branches in the mixture is at the most 30% by weight in relation to the overall weight of the polysaccharide and the polyglucan.

  • Patent number: 6562600
    Abstract: The cyclic tetrasaccharide, cyclo{-6)-&agr;-D-Glcp-(1,3)-&agr;-D-Glcp-(1,6)-&agr;-D-Glcp-(1,3)-&agr;-D-Glcp-(1-}, may be produced by alternanase hydrolysis of complex carbohydrates other than alternan. Panose, pullulan, &agr;-D-Glcp-(1,6)-&agr;-D-Glcp-(1,3)-D-Glc, and D-glucans having alternating &agr;-(1,6) and &agr;-(1,4) linkages, are all hydrolyzed by alternanase to produce this cyclic tetrasaccharide. In this process, the cyclic tetrasaccharide is produced by contacting a solution of one or more of the above-mentioned complex carbohydrates with an amount of alternanase under conditions effective for activity of the enzyme. The substrate panose used in the reaction may be produced from a variety of polysaccharides or oligosaccharides, including starch, maltose, maltodextrins, pullulan, and mixtures thereof.
