Abstract

The invention is in the field of enzymology. More in particular, it provides a method for the isomerization of glucose into fructose wherein the glucose is derived from lignocellulosic material. More in particular, it provides a method for converting glucose into fructose comprising the steps of: providing a composition comprising water, glucose and lignin, enzymatically converting the glucose to fructose in the presence of a glucose isomerase, and optionally purifying the fructose from the solution, wherein the glucose isomerase comprises an amino acid sequence that is at least 90% identical with the sequence according to SEQ ID NO: 1 or SEQ ID NO: 2.
