  • ENZYMATIC TREATMENT OF LIGNOCELLULOSIC MATERIALS
    Publication number: 20090098616
    Abstract: A method for treating plant materials to release fermentable sugars is disclosed. More specifically, a two-stage enzymatic hydrolysis process for treating lignocellulosic materials and producing a sugar rich process stream that may subsequently be subjected to fermentation to produce biofuels and chemicals is disclosed.
    Type: Application
    Filed: October 8, 2008
    Publication date: April 16, 2009
    Inventors: Murray Burke, Bradley Saville, Claudia Ishizawa
  • TREATMENT OF LIGNOCELLULOSIC MATERIALS UTILIZING DISC REFINING AND ENZYMATIC HYDROLYSIS
    Publication number: 20090098618
    Abstract: A method for treating plant materials to release fermentable sugars is disclosed. More specifically, lignocellulosic materials are subjected to disc refining together with enzymatic hydrolysis to produce a sugar rich process stream that may subsequently be subjected to fermentation to produce biofuels and chemicals is disclosed.
