  • Production and composition of fructose syrup
    Patent number: 11447805
    Abstract: Disclosed herein are aqueous compositions comprising fructose and methods of production thereof. A method for producing an aqueous composition comprising fructose can comprise, for example, conducting an enzymatic reaction by contacting water, sucrose, and a glucosyltransferase enzyme that synthesizes poly alpha-1,3-glucan having at least 30% alpha-1,3-linkages. A soluble fraction produced by such a reaction comprises at least about 55% fructose on a dry weight basis, and can be separated from insoluble poly alpha-1,3-glucan product(s), thereby providing an aqueous composition comprising fructose.
    Type: Grant
    Filed: February 22, 2019
    Date of Patent: September 20, 2022

  • Oil release with N-lauroyl amino acid-based compounds
    Patent number: 8697614
    Abstract: Chemical compounds that are N-lauroyl amino acids or derivatives thereof were found to have oil-releasing activity. Solutions containing these compounds may be introduced into oil reservoirs or onto oil-contaminated surface sites to release oil from oil-coated surfaces. The released oil may be recovered for further processing or waste disposal.
