  • Patent number: 9301540
    Abstract: A prebiotic composition comprising soluble extractable material from a lignocellulosic source. A method of producing a composition, comprising providing a lignocellulosic source; extracting soluble materials from the lignocellulosic source to produce soluble extractable material; and processing the soluble extractable material to yield a prebiotic composition, wherein the prebiotic composition comprises hemicellulose and exhibits prebiotic activity.
    Type: Grant

  • Publication number: 20140378412
    Abstract: A method comprising administering an oligosaccharide composition to an organism having a gastrointestinal system to affect the production of GHG produced by the organism allowing for a reduction of the GHG produced by the organism while optimizing the health, feed intake, and protein synthesis of the organism so that management of the organism may realize the synergistic effects of maximizing both typical organism commodity-type concerns (e.g., size and production metrics) and atypical organism commodity-type concerns (e.g., carbon credit trading/monetization). A gas-reducing composition comprising soluble extractable material from a lignocellulosic source.

  • Patent number: 6030562
    Abstract: A method of forming a consolidated wood product is disclosed wherein zinc borate and resin are mixed with cellulosic material to form treated cellulosic material, followed by applying heat and pressure to form a consolidated cellulosic product. A consolidated product comprises zinc borate, resin, and cellulosic material, wherein the zinc borate is distributed throughout the lignocellulosic material. A steam injection process is also disclosed.

  • Patent number: 5432247
    Abstract: A fusible phenolic resin and a dialkyl-N,N-bis(hydroxyalkyl)aminoalkyl phosphonate are condensed to form a water-insoluble resin having fire retardant properties. Fire resistant materials are made by causing the condensation to occur in situ when a normally flammable material and the reactants are mixed and the mixture is heated at 250.degree. F. to 480.degree. F. Wooden articles such as molded hardboard roofing shingles of this invention do not lose their fire resistance after being soaked with rain repeatedly.
