  • Publication number: 20150344923
    Abstract: The present compositions and methods relate to a beta-mannanase from Thermobifida fusca, polynucleotides encoding the beta-mannanase, and methods of make and/or use thereof. Formulations containing the beta-mannanase are suitable for use in hydrolyzing lignocellulosic biomass substrates, especially those comprising a measurable level of galactoglucomannan (GGM) and/or glucomannan (GM).

  • Publication number: 20150240278
    Abstract: A method is disclosed for hydrolyzing an alpha-1,5 glucosyl-fructose linkage in a saccharide (disaccharide or oligosaccharide) such as leucrose. This method comprises contacting the saccharide with an alpha-glucosidase enzyme such as transglucosidase or glucoamylase under suitable conditions, during which contacting step the enzyme hydrolyzes at least one alpha-1,5 glucosyl-fructose linkage of the saccharide. This method is useful for reducing the amount of leucrose in a filtrate isolated from a glucan synthesis reaction, for example.
