Reaction Steps
Based on this idea, as shown in Example 6, glucose and ethanol were added and allowed to react in a conversion reaction of D-arabitol using Gluconobacter oxydans ATCC621 and the effect of their addition was examined. As a result, a considerable effect of addition was recognized as shown in Example 6. That is, when no carbon source was added, a portion of D-xylulose remained unreacted, giving a low yield of xylitol whereas with the addition of a carbon source, reduction of D-xylulose to xylitol proceeded advantageously and the yield of xylitol (based on the yield of D-arabitol) reached at most 98%.
