AIMS
Four selected fungi were screened for their ability to decolourize a textile effluent and commercial reactive dyes in a solid medium.
METHODS AND RESULTS
Ligninolytic enzymes activities (lignin peroxidase, manganese peroxidase and laccase) and siderophores presence were monitored in decolourized plates.
RESULTS
The results showed low lignin peroxidase activity and no manganese peroxidase activity was detected for all fungi. Laccase activity was observed in Reactive Blue 19 decolourized plates by Trametes versicolor and Trametes villosa. Siderophores presence was observed in Trametes versicolor, Phanerochaete chrysosporium and Lentinus edodes decolourized plates.
CONCLUSION
Lentinus edodes displayed the greatest decolourization ability both in terms of extent and rapidity of decolourization.
SIGNIFICANCE AND IMPACT OF THE STUDY
The transformation observed for dyes open the possibility to study siderophores to treat dyes and textile effluents.
目的
筛选四种选定的真菌，以评估它们在固体培养基中对纺织废水和商业活性染料进行脱色的能力。
方法与结果
在脱色平板中监测木质素分解酶活性（木质素过氧化物酶、锰过氧化物酶和漆酶）以及铁载体的存在情况。
结果
结果表明，所有真菌的木质素过氧化物酶活性较低，且未检测到锰过氧化物酶活性。在云芝和毛云芝对活性蓝19脱色的平板中观察到漆酶活性。在云芝、黄孢原毛平革菌和香菇脱色的平板中观察到铁载体的存在。
结论
就脱色程度和速度而言，香菇表现出最强的脱色能力。
研究的意义和影响
观察到的染料转化为研究利用铁载体处理染料和纺织废水开辟了可能性。
