  • Publication number: 20190256877
    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.

  • Publication number: 20190048376
    Abstract: A method is disclosed for hydrolyzing an alpha-1,3 or alpha-1,6 glucosyl-glucose linkage in a saccharide (disaccharide or oligosaccharide). This method comprises contacting the saccharide with an alpha-glucosidase enzyme such as transglucosidase under suitable conditions, during which contacting step the enzyme hydrolyzes at least one alpha-1,3 or alpha-1,6 glucosyl-glucose linkage of the saccharide. This method is useful for reducing the amount of oligosaccharides in a filtrate isolated from a glucan synthesis reaction, for example.

  • Publication number: 20180066214
    Abstract: Compositions comprising cellulase and at least one poly alpha-1,3-glucan ether compound having a degree of substitution with an organic group of about 0.05-3.0 are disclosed. Such compositions can be dry or aqueous, the latter of which can have a viscosity of at least about 10 cPs. The disclosed composition can be in the form of a personal care product, household product, or industrial product, for example. Also disclosed are a method for preparing an aqueous composition comprising cellulase and a poly alpha-1,3-glucan ether compound, and a method of treating a material such as fabric by contacting it with this aqueous composition.

  • Publication number: 20150064748
    Abstract: A process for producing poly alpha-1,3-glucan with reduced molecular weight is disclosed. The process comprises contacting water, sucrose, a polar organic solvent, and a glucosyltransferase enzyme in a solution to produce poly alpha-1,3-glucan. This contacting step results in the production of poly alpha-1,3-glucan having a reduced molecular weight compared to the molecular weight of a poly alpha-1,3-glucan made in the absence of the polar organic solvent.
