A laccase-mediator system (LMS) for biobleaching was applied to a bleached chemical pulp dyed with stilbene dye Direct Yellow 11. Of mediators tested, 2,2'-azinobis(3-ethylbenzthiazoline-6-sulfonate) (ABTS) was found to be more effective than either violuric acid (VA) or N-hydroxybenzotriazole (HBT), which had been shown to be superior to ABTS when bleaching virgin chemical pulp. The laccase-ABTS system removed more than 60% of the color.
一种用于生物漂白的漆酶-介体系统（LMS）被应用于用二苯乙烯染料直接黄11染色的漂白化学浆。在所测试的介体中，发现2,2'-偶氮双（3-乙基苯并噻唑啉-6-磺酸盐）（ABTS）比紫尿酸（VA）或N-羟基苯并三唑（HBT）更有效，而在漂白原生化学浆时，VA和HBT已被证明优于ABTS。漆酶-ABTS系统去除了超过60%的颜色。
