Abstract
The compositions contain intracellular glucose-isomerase which is enclosed in platelet or filamentary structures based on cellulose ester. In addition to the cellulose ester and micro-organism cells, e.g. Streptomyces phaeochromogenes, these compositions contain a sparingly water-soluble magnesium compound and optionally a sparingly water- soluble cobalt compound. These compositions make it possible to isomerise glucose into levulose in a continuous process, with the addition of either no, or a small amount of magnesium ions to the glucose syrup to be isomerised and without the addition of cobalt ions.
