摘要:
The present invention provides a biodegradable article formed from enzyme-synthesized amylose using phosphorylase, wherein the enzyme-synthesized amylose is composed of glucose monomers exclusively bonded by α-1,4-glucosidic likage and has a weight average molecular weight of not less than 100 kDa, preferable not less than 600 kDa. The enzyme-synthesized amylose employed in the present invention has a molecular weight distribution (Mw/Mn) of not more than 1.25 and can be chemically modified if desired.The biodegradable article of the present invention can be produced by (a) the enzyme-synthesized amylose and/or its modified one, or a combination of the amylose (a) and another polymer material (b).
摘要:
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.
摘要:
A method for activating a denatured protein, includes the steps of: adding a detergent to the denatured protein to allow a protein-detergent complex to be formed; and adding high-molecular weight amylose to the protein-detergent complex so that the high-molecular weight amylose removes the detergent.

摘要:
A method for producing an amylose-containing rayon fiber, comprising the steps of: mixing an aqueous alkaline solution of amylose with viscose to obtain a mixed liquid, spinning the mixed liquid to obtain an amylose-containing rayon fiber, and bringing the amylose-containing rayon fiber into contact with iodine or polyiodide ions, thereby allowing an amylose in the amylose-containing rayon fiber to make a clathrate including the iodine or polyiodide ions, wherein the amylose is an enzymatically synthesized amylose having a weight average molecular weight of 3×104 or more and 2×105 or less. A method for collecting iodine from brackish water with high efficiency utilizing the amylase-containing rayon fibers.
