METHOD FOR PURIFYING SUGAR PHOSPHATE

Japanese Patent JP2005041784

A

To provide a method by which application to liquids after completing reactions of both an enzymic method and a fermentation method can be made and a sugar phosphate such as G-1-P (glucose-1-phosphate) or its salt can be purified at a low cost.

The method for purifying the sugar phosphate or its salt comprises subjecting a mixed aqueous solution containing the sugar phosphate or its salt and sugars to electrodialysis using a monovalent ion-nonselective anion exchange membrane and thereby removing the sugars. Furthermore, the method for purifying the sugar phosphate or its salt comprises subjecting the mixed aqueous solution containing the sugar phosphate or its salt, sugars and phosphoric acid or its salt to the electrodialysis using the monovalent ion-nonselective anion exchange membrane and electrodialysis using a monovalent ion-selective anion exchange membrane and thereby removing the sugars and phosphoric acid or its salt.
