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.

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.

A fructose transferring enzyme is immobilized by adsorption on a granular carrier having a primary to quaternary amine. The carrier is preferably an epoxy polymer, a vinyl polymer or a chitosan derivative having a primary, secondary or tertiary amine. Immobilization can be performed without or with a crosslinking agent. The immobilized enzyme is used for producing fructooligosaccharides by passing a sucrose solution through a column containing the immobilized enzyme.
