Decolorization of Synthetic Dyes by Ligninolytic Enzymes from Trametes hirsuta D7

Decolorization and detoxification of textile dyes with a laccase from Trametes hirsuta.

Trametes hirsuta and a purified laccase from this organism were able to degrade triarylmethane, indigoid, azo, and anthraquinonic dyes. Initial decolorization velocities depended on the substituents on the phenolic rings of the dyes. Immobilization of the T. hirsuta laccase on alumina enhanced the thermal stabilities of the enzyme and its tolerance against some enzyme inhibitors, such as halide...

Trametes hirsuta Dyes with a Laccase from Decolorization and Detoxification of Textile

Decolorization of dyes from textile wastewater by Trametes versicolor.

The white rot fungus Trametes versicolor was applied to the decolourisation of three synthetic textile dyes in the presence and absence of glucose. Different initial dye concentrations were tested and approximately 97% decolourisation was achieved. It was found that fungal metabolism induced by the glucose as well as the pH play an important role in the decolourisation process. This treatment w...

Potential of Trametes Hirsuta to Produce Ligninolytic Enzymes during Degradation of Agricultural Residues

Trametes hirsuta is an efficient lignin-degrading species due to its ability to produce laccase and Mn-dependent peroxidase. Agricultural residues represent prospective substrates for the bioconversion into fungal biomass and lignocellulolytic enzymes, but also they could be potential environmental pollutants. Evaluation of the potential of T. hirsuta to produce ligninolytic enzymes during soli...
