Versuchsvorschrift

The above experiment was repeated, except that the xylose isomerase was bound on an alumina carrier. The same dextrose feed liquor, pre-adjusted to a pH of 8.3 - 8.4 with 4 N NaOH, was pumped through the column, which was maintained at a temperature of 58°C, at a rate to provide 45% by weight levulose, dry basis, in the effluent. The residence time was less than one hour. The following is an analysis of the pH of the feed syrup and effluent syrup after a prolonged continuous conversion campaign:
