  • Levulinic acid from fungal biomass
    Patent number: 8962883
    Abstract: Systems and methods for producing levulinic acid from fungal biomass are disclosed. In one implementation, a method for distilling levulinic acid from a glucosamine-containing feedstock is disclosed that yields a relatively pure (e.g., 90% or greater) levulinic acid product from an otherwise problematic waste stream.
    Type: Grant
    Filed: May 29, 2010
    Date of Patent: February 24, 2015
    Assignee: Cargill, Incorporated
    Inventors: Larry Todd Banner, John Andrew Bohlmann, Brian J. Brazeau, Tzyy-Jan Han, Paul Loucks, Shannon Nicole Shriver, Shuang Zhou
  • Glucosamine and N-acetylglucosamine compositions and methods of making the same fungal biomass
    Patent number: 8222232
    Abstract: Glucosamine, N-acetylglucosamine and ?-glucan compositions suitable for human or animal consumption or use are disclosed. The glucosamine, N-acetylglucosamine and ?-glucan compositions are derived from fungal biomass containing chitin. Various methods of producing glucosamine, N-acetylglucosamine and ?-glucan compositions are also disclosed.
    Type: Grant
