  • Production of glucuronic acid using myo-inositol oxygenase from cryptococcus neoformans
    Patent number: 7923231
    Abstract: A method is disclosed for increasing the specific activity of myo-inositol oxygenase. The method includes incubating a mixture including myo-inositol oxygenase and a non-sulfur containing reductant under conditions effective to increase the specific activity of the myo-inositol oxygenase. Also disclosed are methods for producing D-glucuronic acid and glucurono-?-lactone comprising incubating a mixture including myo-inositol, myo-inositol oxygenase, and oxygen under conditions effective to form 5 grams D-glucuronic acid per liter of the mixture to 400 grams D-glucuronic acid per liter of the mixture. Glucurono-?-lactone can be produced from the D-glucuronic acid product. Also disclosed are organisms and nucleic acids suitable for use in such methods.
