Abstract
A method by which a cellooligosaccharide can be produced inexpensively at high percentage yield is provided. In the method for producing a cellooligosaccharide according to an embodiment, at least one primer selected from the group consisting of glucose, cellobiose, and derivatives in which anomeric positions of glucose and cellobiose are modified and sucrose are subjected to, in the presence of phosphoric acid, actions of sucrose phosphorylase and cellodextrin phosphorylase. In this case, in the reaction system, the concentration of phosphoric acid is set to 3 mol/m3 or more and 120 mol/m3 or less.
Claims6
A method for producing a cellooligosaccharide, the method comprising a reaction step of subjecting (i) at least one primer selected from the group consisting of glucose and cellobiose and (ii) sucrose, in the presence of phosphoric acid, to actions of sucrose phosphorylase from Leuconostoc mesenteroides and cellodextrin phosphorylase from Clostridium thermocellum, wherein, in a reaction system, a concentration of phosphoric acid including an amount of a-glucose-1-phosphate contained as an intermediate product is 3 mol/m3 or more and 120 mol/m3 or less.
