PROCEDURE TO PRODUCE HYDROGEN PEROXIDE AND 2-KETO-D-GLUCONIC ACID. IT INCLUDES THE FOLLOWING OPERATIONS: FIRST, D-GLUCOSE IN AQUEOUS SOLUTION IS REACTED WITH OXYGEN AND A FIRST ENZYME SELECTED BETWEEN PYRANOSE-2-OXIDASE AND GLUCOSE-2-OXIDASE IN ORDER TO CATALYZE THE DUCOUND CARDONATION OF THE SECOND -GLUCOSONE; SECOND, THE D-GLUCOSONE IN AQUEOUS SOLUTION IS REACTED WITH OXYGEN AND GLUCOSE-1-OXIDASE TO CATALYZE THE OXIDATION OF THE FIRST CARBON OF THE D-GLUCOSONE AND PRODUCE HYDROGEN PEROXIDE AND D-2-GLYCONIC ACID; AND LASTLY, THE 2-KETO-D-GLUCONIC ACID IS RECOVERED. |
