A set of 50 randomly chosen fungal strains belonging to different basidiomycete species was tested for H2O2 and ligninolytic enzyme production and for decolorization of synthetic dyes Orange G and Remazol Brilliant Blue R. The decolorization capacity of individual strains was influenced by the level of H2O2 and laccase activity. The strains producing H2O2 at a concentration of 1.0-1.5 microM exhibited the most efficient decolorization; higher or lower H2O2 concentration reduced this ability. None of the strains without a detectable laccase activity was able to decolorize the tested dyes.
对一组随机挑选的50种属于不同担子菌物种的真菌菌株进行了测试，检测其过氧化氢和木质素分解酶的产生情况以及对合成染料橙黄G和活性艳蓝R的脱色能力。单个菌株的脱色能力受过氧化氢水平和漆酶活性的影响。产生浓度为1.0 - 1.5微摩尔的过氧化氢的菌株表现出最有效的脱色效果；过氧化氢浓度过高或过低都会降低这种能力。没有可检测到漆酶活性的菌株均无法使测试染料脱色。
