  • Biodegradable polymeric nanocomposite compositions particularly for packaging
    Publication number: 20100076099
    Abstract: Specific polymer blends of polylactic acid (PLA) and polyhydroxybutyrate (PHB) and poly-(butylenes adipate-co-terephthalate (PBAT) as a fatty acid quaternary ammonium modified clay. The blends are particularly useful for barrier packaging.
    Type: Application

  • Device for detecting oxygen with oxidase
    Patent number: 5804401
    Abstract: A method and device (10) for removing oxygen using a reduced oxidase enzyme and for providing a calorimetrically detectable signal of the presence of the oxygen. A reduced laccase or ascorbate oxidase is preferably provided with a substrate which reduces the oxidase. Color is generated which can be detected visually or by other means such as a spectrophotometer. The method and device are particularly useful in the food, pharmaceutical and biological industries.
    Type: Grant
    Filed: January 15, 1997
    Date of Patent: September 8, 1998
    Assignee: Board of Trustees operating Michigan State University
    Inventors: Alicia E. Gardiol, Ruben J. Hernandez, Bruce R. Harte
  • Method and device for reducing oxygen with a reduced oxidase with color formation
    Patent number: 5654164
