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]

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

A novel &bgr;-fructofuranosidase gene and a &bgr;-fructofuranosidase encoded by the gene, a process for isolating a &bgr;-fructofuranosidase gene using the novel &bgr;-fructofuranosidase gene, and a novel &bgr;-fructofuranosidase obtained by this isolation process are disclosed. A novel mold fungus having no &bgr;-fructofuranosidase activity suitable for the production of &bgr;-fructofuranosidase, and a system for producing a recombinant &bgr;-fructofuranosidase using the novel mold fungus as a host is disclosed. Further, a &bgr;-fructofuranosidase variant which selectively and efficiently produces a specific fructooligosaccharide such as 1-kestose from sucrose is disclosed.
