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 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

There is provided an endoglucanase enzyme, which is useful for reducing fuzz of regenerated cellulose-containing fabrics, improving the touch and appearance, color clarification, localized variation in color, reducing stiffness and using it as components of a detergent, as well as deinking waste paper and improving freeness of paper pulp. A cDNA coding for the endoglucanase enzyme NCE5 was cloned and its DNA sequence and amino acid sequence derived from it were determined.

The present invention relates to a cellulase preparation comprising nonionic surfactants together with endoglucanases derived from Zygomycetes; a detergent composition comprising the above cellulase preparation with detergent components; a method of treating fabric which comprises treating cellulose-containing fabric with the above cellulase preparation so as to improve the properties of the fabric; a method of deinking waster paper which comprises a step of treating waste paper with the above cellulase preparation together with a deinking agent; and a method of improving the freeness of paper pulp which comprises a step of treating paper pulp with the above cellulase preparation.

Cellulase preparation containing nonionic surfactant and method of treating fiber

It is an object of the present invention to provide enzymes that have high endoglucanase activity and yet exhibit high activity even under alkaline conditions, and genes encoding the same. The enzyme according to the invention has the following properties: a) exhibiting endoglucanase activity; and b) capable of completely removing fuzz from regenerated cellulose fabrics at a concentration of 1 mg of the protein/L or below. The enzyme of the invention having endoglucanase activity is a protein comprising the amino acid sequence as shown in SEQ ID NO: 1, 3, 5, 7, 9 or 11; a modified protein thereof exhibiting endoglucanase activity; or a homologue of the protein or the modified protein.

Endoglucanases and cellulase preparations containing the same

An expressing system which enables a large amount of production of a protein in Humicola, in particular, and particularly host-vector systems and a process for producing a protein using the systems, wherein an expression vector comprising the regulator sequences, i.e., the promoter, the signal sequence, and the terminator, of the cellulase NCE1 gene or NCE2 gene derived from is constructed and used. The expression vector enables highly efficient production of cellulase NCE4, for example, in at a rate as high as about 4.5 g or more per one liter of culture.
