Patent number: 6691783Abstract: A novel microorganism producing a nontoxic, non-antigenic exopolysaccharide is taught. The exopolysaccharide has neutral sugars migrating at the same rate as mannose, fucose, fructose and galactose, acidic sugars migrating at the same rate as fucose and amine sugars migrating at the same rate as glucose and fucose, and wherein the ratio of galactose:fucose:glucose:mannose is about 1:2:3:6. The microbe and the exopolysaccharide have uses as a biofilm in geologic applications and have several consumer uses as food and drug polymers and use as a plasma extender.Type: GrantFiled: October 25, 2000Date of Patent: February 17, 2004Assignee: The Board of Regents, The University of Texas SystemInventors: Lee A. Bulla, Jr., John P. Turner

Publication number: 20030225263Abstract: 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.Type: ApplicationFiled: May 21, 2002Publication date: December 4, 2003Inventors: James M. Gaddy, Penelope A. Patton

Patent number: 6602996Abstract: The invention relates to a modified gellan gum in which the total acyl content as well as the ratio of acyl substituent groups to glycerate substituent groups per linear saccharide repeat unit is altered to be higher than 1. The invention further relates to a process for the modification of a gellan gum to alter its acyl content in which the gum is treated with a weak base such as sodium or potassium carbonate or a suitable phosphate. The process enables “tailor made” gums having appropriate setting temperatures and theological properties to be made. Novel compositions containing them are also claimed.Type: GrantFiled: December 8, 2000Date of Patent: August 5, 2003Assignee: CP Kelco U.S., Inc.Inventors: Graham Sworn, You-Lung Chen, Neil A. Morrison, Todd Talashek, Ross Clark

Patent number: 6590096Abstract: The present invention relates to a method for producing porous polysaccharide beads, comprising: (a) mixing a water-based solution of a polysaccharide under stirring with an essentially water-immiscible first organic phase to form an emulsion which separates into two continuous phases; (b) adding a second organic phase comprising an emulsifier and an organic solvent to form a three-phase system; (c) allowing the three-phase system to emulsify; and (d) decreasing the temperature below the gelling point of the polysaccharide, thereby obtaining beads having two sets of pores, said method being characterised in that the emulsifier is a water-insoluble polymer capable of stabilizing said three-phase system.Type: GrantFiled: May 18, 2001Date of Patent: July 8, 2003Assignee: Amersham Biosciences ABInventors: Hans Berg, Mats Carlsson
