A process for the enhancement of the acitivity of an enzyme, especially in a detergent composition, comprises the addition thereto, as mediator for such enhancement, a compound of the formula: [A].(X)x.(Y)y.(Z)z wherein: A is an (hetero)aromatic radical; X is -N=S or -N=O; Y is -SH or -OH; Z is a water-solubilising group; x is 1 or 2; y is 1, 2 or 3; z is 0, 1, 2, 3 or 4; or a tautomer, or transition metal complex, thereof. The enhanced active enzyme may be used: (i) in the degradative bleaching of pulp for paper production; (ii) in the degradative bleaching of stains on textiles during washing: (iii) in the modification, breakdown or bleaching of lignin, especially during the production of paper pulp; (iv) in the degradation of organic material (especially dyestuffs) in waste water; (v) in the degradative bleaching of migrating dyes in a washing process, so that the transfer of such dyes is inhibited. The enzyme is preferably an oxidoreductase, especially an oxidase, peroxidase (particularly lignin peroxidase or manganese peroxidase) or laccase. |
