This invention provides a novel carrier for enzyme immobilization and an immobilized enzyme. The carrier for enzyme immobilization according to an embodiment comprises a porous material and cellulose that has an amino group-containing substituent at an anomeric position and is immobilized on the porous material. The immobilized enzyme contains the carrier for enzyme immobilization and an enzyme immobilization on the cellulose. The carrier for enzyme immobilization is obtained by adding an acid to an aqueous solution in which cellulose having an amino group-containing substituent at an anomeric position is dissolved in an aqueous alkaline solution to deposit the cellulose in the presence of a porous material. The immobilized enzyme is obtained by immobilizing an enzyme on the cellulose.

Nonionic, water-soluble cellulose ethers are disclosed with hydroxyalkyl groups and ω-alkynyl groups, each joined to the cellulose via an ether bond, the degree of molar substitution MS(alkyne) being in the range from 0.001 to 0.30. The cellulose ethers may further contain azido groups, preferably 3-azido-2-hydroxypropyl groups, likewise joined to the cellulose by an ether bond, the MS(AHP) being in the range from 0.001 to 0.3. To obtain an adhesive, cellulose ether is mixed with water or. if the cellulose ether contains no alkyne groups, is mixed additionally with a non-ionic cellulose ether containing ω-alkyne groups and hydroxyalkyl groups, each bonded to the cellulose by ether bonds. The mixture is applied to at least one of the surfaces to be bonded and then is contacted with a copper(I) catalyst or a ruthenium catalyst. The adhesive is especially suitable for bonding wood, paper, cardboard or other cellulosic material.
