Procedure
As illustrated in FIG. 2, addition of glucose and ethanol resulted in the production of an significantly increased amount of xylitol, so that a considerable effect of their addition was observed. In the case where no carbon source was added, D-arabitol was oxidized substantially completely to D-xylulose. Even in the reaction without addition of any carbon source, prevention of pH at the time of reaction from decreasing by addition of calcium carbonate resulted in a slight increase in the yield of xylitol, more particularly 1.23% (w/v) xylitol was produced in 24 hours' reaction. However, a portion of D-xylulose remained unreacted, no further increase in yield did occur. In contrast, with addition of a carbon source, D-xylulose was reduced to xylitol substantially completely, and at the point in time of 24 hours, xylitol was produced and accumulated in a yield as high as 5.24% (w/v) (98% based on D-arabitol).
