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.
活性黑5工业印染废水通过游离漆酶和固定化漆酶进行脱色处理。酶的稳定性（游离酶为194小时，固定化酶为79小时）取决于染液成分和染料的化学结构。在固定化漆酶的脱色实验中，观察到两种现象——因吸附在载体上而导致的脱色（79%）和因酶作用而导致的染料降解（4%）。用酶循环利用后的废水进行染色，无论对于亮色染料还是暗色染料，都能使颜色保持一致。
