Abstract

The invention is in the field of enzymology. More in particular, it provides a method for the isomerization of xylose into xylulose wherein the xylose is derived from lignocellulosic material. More in particular, it provides a method for converting xylose into xylulose comprising the steps of: providing a composition comprising water, xylose and lignin, enzymatically converting the xylose to xylulose in the presence of a xylose isomerase, and optionally purifying the xylulose from the solution, wherein the xylose 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
