Patent number: 9926527Abstract: 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 inventive methods of production of such an improved diutan polysaccharide, as well as the novel cloned genes required to produce the improved diutan within such a method, are also encompassed within this invention. Additionally, the novel engineered Sphingomonas strain including the needed DNA sequence is encompassed within this invention.Type: GrantFiled: December 29, 2014Date of Patent: March 27, 2018Assignee: CP Kelco U.S., Inc.Inventors: Nancy E. Harding, Yamini N. Patel, Russell Coleman, Steven Matzke

Patent number: 8278438Abstract: 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: September 28, 2010Date of Patent: October 2, 2012Assignee: CP Kelco U.S., Inc.Inventors: Nancy E.
