Abstract Reactive Black 5 industrial dyeing effluent was decolourized by free and immobilized laccase. The stability of the enzyme (194 h free and 79 h immobilized) depended on the dyeing liquor composition and the chemical structure of the dye. In the decolourization experiments with immobilized laccase, two phenomenons were observed--decolourization due to adsorption on the support (79\%) and dye degradation due to the enzyme action (4\%). Dyeing in the enzymatically recycled effluent provided consistency of the colour with both bright and dark dyes.
