  • Production method and preparation method of glucans
    Patent number: 7229801
    Abstract: A first method for producing glucan comprises the step of allowing a reaction solution containing sucrose, a primer, inorganic phosphate or glucose-1-phosphate, sucrose phosphorylase, and glucan phosphorylase to react to produce glucans. The maximum value of the sucrose-phosphate ratio of the reaction solution from the start of the reaction to the end of the reaction is no more than about 17. A second method for producing glucan comprises the step of allowing a reaction solution containing sucrose, a primer, inorganic phosphate or glucose-1-phosphate, sucrose phosphorylase, and glucan phosphorylase to react to produce glucans. The reaction is conducted at a temperature of about 40 C to about 70 C.

  • Method of converting beta-1,4-glucan to alpha-glucan
    Publication number: 20070092949
    Abstract: A method for production of an ?-glucan from a ?-1,4-glucan is provided, comprising: reacting a solution containing ?-1,4-glucan, a primer, a source of phosphoric acid, ?-1,4-glucan phosphorylase, and ?-1,4-glucan phosphorylase to produce an ?-glucan. In this method, said ?-1,4-glucan may be cellobiose, and said ?-1,4-glucan phosphorylase may be cellobiose phosphorylase.
