Abstract
A method for producing a cellooligosaccharide that enables the formation of a cellooligosaccharide having a high degree of polymerization to be suppressed in enzymatic synthesis of a cellooligosaccharide, the method comprising reacting α-glucose-1-phosphate and at least one primer selected from the group consisting of glucose, cellobiose, and alkylated glucose with cellodextrin phosphorylase in a mixed solvent containing water and a water-soluble organic solvent.
Claims6
A method for producing a cellooligosaccharide, comprising:
- reacting α-glucose-1-phosphate and at least one primer selected from the group consisting of glucose and alkylated glucose with cellodextrin phosphorylase in a mixed solvent containing water and a water-soluble organic solvent, so as to obtain a cellooligosaccharide having the following structure:
- wherein n is a degree of polymerization and an integer of 5 to 11, and R represents a hydrogen or an alkyl group having 1 to 12 carbon atoms, and
- an average degree of polymerization is 6.0 to 9.0, and
- wherein the amount of the water-soluble organic solvent is 5 to 30 volume % based on the mixed solvent taken as 100 volume %.
