One purpose of the present invention is to provide a high molecular weight glucan having both properties low digestion rate and high digestibility. A high molecular weight glucan that has property digested slowly and contains almost no indigestible ingredients is produced by enzymatic reactions of (1) a specific concentration of branching enzyme and (2) 4-&#x3b1;-glucanotransferase and/or an exo-type amylase to a branched glucan used as a substrate.

High molecular weight glucan having low digestion rate

One object of the present invention is to provide a method of improving the affinity of a solvent for the surface of a hardly soluble or insoluble substances. Further object of the invention is providing a molded article comprising a hardly soluble or insoluble substances using the solution of a hardly soluble or insoluble substances. A method for improving affinity of a substance surface for a solvent, comprising: bringing the substance surface into contact with water-soluble xylan and the solvent, wherein the substance is hardly soluble or insoluble in the solvent in the absence of the water-soluble xylan. A solution comprising an added water-soluble xylan, a substance, and a solvent, wherein the substance is hardly soluble or insoluble in the solvent in the absence of the water-soluble xylan. A molded article comprising the added water-soluble xylan and the hardly soluble substance.

Affinity of hardly soluble or insoluble substance solvent by water-soluble xylan

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&#xd7;10or more and 2&#xd7;10or less. A method for collecting iodine from brackish water with high efficiency utilizing the amylase-containing rayon fibers.

Objective is to provide an aqueous composition for conductive coating which enables to form a conductive coating. In more specific embodiment, an object of the present invention is to provide an aqueous composition for conductive coating which enables to form a conductive and transparent coating, while being excellent in environmental safety and dispersion stability. An aqueous composition for conductive coating, comprising a water-soluble xylan, a resin and a carbon nanotube in an aqueous medium. The carbon nanotube may be a multilayer carbon nanotube or a single-layer carbon nanotube.

Aqueous composition for conductive coating

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 &#x3b1;-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).

Biodegradable articles obtained from enzymatically synthesized amylose

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.

Production method and preparation method of glucans

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.

Method for activating denatured protein
