Patent number: 8053216Abstract: A new method to produce formulations of bacterial cellulose that exhibit improved viscosity-modifying properties particularly with low energy applied to effectuate viscosity changes therewith is provided. Such a method includes the novel co-precipitation with a water soluble co-agent that permits precipitation in the presence of excess alcohol to form an insoluble fiber that can than be utilized as a thickener or suspension aid without the need to introduce high energy mixing. Such bacterial cellulose properties have been available in the past but only through highly labor and energy intensive processes. Such an inventive method as now proposed thus provides a bacterial cellulose-containing formulation that exhibits not only properties that are as effective as those for previous bacterial celluloses, but, in some ways, improvements to such previous types. Certain end-use compositions and applications including these novel bacterial cellulose-containing formulations are also encompassed within this invention.Type: GrantFiled: May 23, 2005Date of Patent: November 8, 2011Assignee: CP Kelco U.S., Inc.Inventors: Zhi-Fa Yang, Neil A. Morrison, Todd A. Talashek, David F. Brinkmann, Don DiMasi, You Lung Chen

Patent number: 7868167Abstract: The production of a diutan polysaccharide exhibiting increased viscosity properties as compared with previously produced polysaccharide of the same type of repeating units. Such an improved diutan polysaccharide is produced through the generation of a derivative of Sphingomonas sp. ATCC 53159 that harbors a multicopy broad-host-range plasmid into which genes for biosynthesis of diutan polysaccharide have been cloned. The plasmid provides the capability within the host Sphingomonas strain to produce multiple copies of genes for such polysaccharide synthesis. In such a manner, a method of not just increased production of the target diutan polysaccharide, but also production of a diutan polysaccharide of improved physical properties (of the aforementioned higher viscosity) thereof is provided. Such a diutan polysaccharide has proven particularly useful as a possible viscosifier in oilfield applications and within cement materials.Type: GrantFiled: November 1, 2005Date of Patent: January 11, 2011Assignee: CP Kelco U.S., Inc.Inventors: Nancy E.

Publication number: 20090306254Abstract: Paint formulations that exhibit improved performance characteristics due to the presence of a combination of a cellulose ether (carboxymethylcellulose and/or hydroxyethylcellulose) and a network building polymer (gellan gum, carrageenan, etc., as examples) as a thickening system therein are provided. Such a combination permits long-term shelf stability of the paint formulation while simultaneously according effective flow, leveling, and other important properties to the final paint formulation. The combination of the cellulose ether and a network building polymer allows for a lower viscosity cellulosic compound to impart the desired rheological behavior therein while also permitting the other desirable characteristics noted above. Such paint compositions also exhibit improved atomization for spray applications with such a thickening system.Type: ApplicationFiled: August 17, 2009Publication date: December 10, 2009Applicant: CP KELCO U.S., INC.Inventors: Maarten van der Wielen, Phil Winston, John Swazey, Ross Clark, Maarit Lahtinen

Publication number: 20090136644Abstract: A multi-layer self-separating gel is described. A food composition comprising a first layer and a second layer comprises water, low acyl gellan gum, and an emulsifier. The composition can further comprise a third layer. A process of preparing a multi-layered food composition can comprise the steps of dry blending the low acyl gellan gum and the emulsifier to form a dry blend; adding the dry blend to water to form a mixture; agitating the mixture; heating the mixture to a temperature above about 54° C.; subjecting the mixture to high shear mixing at a temperature above about 54° C.; cooling the mixture to about 54° C. while continuing to mix said mixture; and ceasing the mixing of the mixture. Lack of protein in the gel minimizes its allergenicity; the gel is vegetarian; and the gel's physical properties allow for the potential of creating a shelf stable product.Type: ApplicationFiled: November 28, 2007Publication date: May 28, 2009Applicant: CP KELCO U.S., INC.Inventors: Ted Anthony Russin, Raymond Charles Valli
