Abstract:
A process for producing a saccharide composition containing a glucosyl-transferred saccharide, which comprisescontacting .beta.-D-glucose-1-phosphoric acid and/or its salt and other saccharide with a kojibiose phosphorylase obtainable from Thermoanearbium brockii which catalyzes the phosphorolysis of kojibiose in the presence of inorganic phosphoric acid and/or its salt to form D-glucose and .beta.-D-glucose-1-phosphoric acid and/or its salt, andremoving impurities other than the glucosyl-transferred saccharides produced during said enzymatic reaction and/or remaining in said reaction mixture by column chromatography or by fermentation using yeast.
