    摘要: The invention relates to enzymatic compositions containing intra-cellular glucose-isomerase which is enclosed in structures based on cellulose ester, their preparation and their use for isomerizing glucose into levulose.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 isomerize 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 isomerized and without the addition of cobalt ions.

    摘要: Polysaccharides produced by fermentation are obtained in a non-fibrous form by washing the product produced by precipitation from the fermentation medium with an aqueous organic liquid in which the proportion of organic liquid is high enough to give a washed product which is not soft, difficult to dry and with a tendency to agglomerate, but not so high that the washed product, after drying and grinding, has a fibrous structure, and then drying and grinding the washed polysaccharide.

    摘要: A process for the enzymatic isomerization of glucose to fructose where the glucose isomerase is combined with magnesium or magnesium and cobalt ions which have been fixed to a cation exchange resin. The glucose isomerase remains combined with the metal ions during the isomerization. The use of the instant complex prolongs the working life of the enzyme and minimizes the need for conventional pH control.
