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.
Conclusions: 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.
