Abstract : The mechanism of oxidation and reduction of D-xylose by cell-free extract of Hansenula polymorpha was studied in medium contain xylose as carbon source. Xylose dehydrogenase which NADP was detected dependent in the cell free extract. Both the oxidation and reduction were coupled in this enzyme and proved by HPLC as xylose; xylitol and xylonic acid. Xylose reductase, NADPH dependent in cell free extract that reduce xylose to xylitol. Both D-xylose and L-arabinose can be used as substrate Xylitol dehydrogenase was also found in the cell free extract which is NAD dependent and xylulose produced in the reaction was identified and it was found to oxidize a variety of polyol sugars.
