PROCESS FOR ENZYMATIC PRODUCTION OF OXIDATION AND REDUCTION PRODUCTS OF MIXED SUGARS

The present invention provides a process for obtaining n+a oxidation and reduction products from a mixture of n sugars selected from the group consisting of C5 and C6 sugars， wherein n is at least 2 and a is at least 1， wherein at least two of the sugars in the mixture are present at a non-equimolar ratio to each other， wherein， in a first stage， at least one of the sugars which are present at a non-equimolar ratio to each other is oxidized enzymatically and， at the same time， at least one of the other sugars present at a non-equimolar ratio to each other is reduced enzymatically， and wherein， in the first stage， a portion of at least one of the sugars present at a non-equimolar ratio to each other is not converted， and which is characterized in that， in at least a second stage， at least a portion of the sugar not converted in the first stage is oxidized enzymatically by half and， respectively， is reduced enzymatically by the remaining half.
