Reaction Steps
Production of D-lyxose, which is a rare sugar, from D-glucose was carried out. By using yeast Candida famata R28, D-arabitol was produced from D-glucose with a yield of 50%. This reaction was carried out by a fermentation method. The produced D-arabitol was converted into D-xylulose by an acetic acid bacterium Acetobacter aceti IFO 3281 with a yield of almost 100%. This could be isomerized to D-lyxose by using L-ribose isomerase. The product was purified and crystallized by ion exchange chromatography and the like, and it was confirmed to be D-lyxose by an instrumental analysis.
