A sialogogue characterized by comprising polyglutamic acid or its salt. This sialogogue is blended into an oral composition and a food product. This sialogogue is capable of rendering the oral mucosa pleasant even in the case of severe xerostomia.

Sialogogue, oral composition and food product containing the same

An object of the present invention is to provide a &#x3b2;-fructofuranosidase variant whose reaction specificity is improved to be suitable for the production of fructooligosaccharides. According to the present invention, there is provided a &#x3b2;-fructofuranosidase variant consisting of a mutated amino acid sequence of SEQ ID NO: 2 or a mutated homologue thereof, which has mutations at specific amino acid residues.

&#x3b2;-fructofuranosidase variants

A novel endoglucanase derived from, a polynucleotide encoding the endoglucanase, and a cellulase preparation containing the endoglucanase are disclosed. The endoglucanase or cellulase preparation is available for a washing use or fabric processing, such as a color clarification of a cellulose-containing fabric, a reduction of fuzz, an improvement of the touch feel and appearance of the fabric, providing a localized color change to the fabric, or a reduction of stiffness.

Endoglucanase STCE and cellulase preparation containing the same

This invention relates to a protein that is a-derived endoglucanase lacking the cellulose-binding domain and exhibits endoglucanase activity, and a method for using the same. This invention can enhance effects of an endoglucanase enzyme on fabric treatment such as reduction of fuzzing, improvement in feel and appearance, color clarification, partial color change, and softening of cellulose-containing fabrics and on performance improvement in the deinking of waste paper and drainage of paper pulp.

[object Object]

A deinking method using a cellulase which enables the load upon the environment to be reduced; and an evaluation method whereby a cellulase effective in deinking and the effective addition level of the cellulase can be appropriately determined. By proposing pulp-swelling activity (PSA) that elevates the water-retention value of pulp after pulp is reacted with cellulase, it becomes possible to select an enzyme that is effective in cellulase-deinking treatment without lowering the paper strength and to determine the effective enzyme dosage. Namely, a method of deinking waste paper is provided wherein the selection of an effective cellulase and the optimization of the enzyme dosage with the use of PSA as an indication make it possible to minimize the cellulase addition level and lessen the amount of the deinking agent.

Method of deinking waste paper using cellulase without lowering paper strength and method of evaluating the same

A cellulase preparation comprising an endoglucanase derived from Zygomycetes, a cellulose-binding-domain-deleted endoglucanase, or a modified or homologous protein thereof, together with a reducing agent is disclosed. Further, a method of treating cellulose-containing fabric, comprising the step of treating the fabric with the cellulase preparation to improve a property of the fabric, a method of deinking waste paper, comprising the step of treating the waste paper with the cellulase preparation. together with a deinking agent, and a method of improving freeness of paper pulp, comprising the step of treating the paper pulp with the cellulase preparation, are disclosed.

Cellulase preparations containing reducing agent and method of processing fiber

The invention relates to a novel peroxidase enzyme with high dye degradation activity, the genetic information thereof and a method for degrading and decolorizing dye by using the same. The invention enables the degradation and decolorizing of a wide range of dye types in an efficient manner with no occurrence of any problem, such as secondary pollution due to the generation of hazardous byproducts or the discharge of the greenhouse effect gas due to high-level energy consumption. In accordance with the invention, further, the enzyme can be supplied at a large quantity, on the basis of the genetic information, so the enzyme can be applied to the treatment of wastewater containing dyes and the like, in the fields of staining industry and the like.
