Abstract
A method for the enzymatic production of D-fructose from D-glucose in a one-pot synthesis, wherein D-glucose is oxidized enzymatically to D-glucosone and D-glucosone is reduced enzymatically to D-fructose and the use of the D-fructose produced in this way for the production of furan derivatives.
Claims14
A method for producing D-fructose from D-glucose, comprising:
- a) enzymatically oxidizing D-glucose to D-glucosone in a reaction vessel, and
- b) enzymatically reducing the D-glucosone to D-fructose in reaction vessel,
- wherein a redox cofactor is used in step b) and the redox cofactor is recycled by a cofactor regeneration system comprising a redox enzyme
- wherein both enzymatic reaction of steps a) and b) are carried out in the reaction vessel and without the D-glucosone being isolated.
1 more element
A method for producing D-fructose from D-glucose, comprising:
- a) enzymatically oxidizing D-glucose to D-glucosone in a single reaction vessel, and
- b) without removing or isolating any materials involved in step a) from the single reaction vessel, enzymatically reducing the D-glucosone to D-fructose in the single reaction vessel.
