| Outline of Final Research Achievements |
The decomposition and decoloration of hetero bifunctional reactive dyes with an oxidoreductase, laccase were studied. The improvement of wet rubbing fastness of wool fabrics dyed with the reactive dyes and optimum conditions to prevent migration of the dyes in the aqueous washing were also investigated. As a result, the blue dye was found to be decolored rapidly under the conditions at pH 4.5 and 45℃. In addition, the staining on the standard adjacent fabrics in the practical washing was inhibited by using laccase/mediator/nonionic detergent.
The substrate specificity of the laccase for the blue dye was very large and the dye was effectively decolored with the enzyme. Thus it is expected that the enzyme used in this experiment can be applied to the wool dyeing and practical washing.
