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

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...

Purification and characterization of laccase from Marasmius species BBKAV79 and effective decolorization of selected textile dyes

A novel laccase-producing white-rot fungus, Marasmius sp. BBKAV79 (Genbank Accession Number-KP455496, KP455497), was isolated and subjected to purification, characterization and dye decolorization study. The purified enzyme was obtained with a specific activity of 0.226 U mg-1 protein and a final yield of 13.5 %. The enzyme was found to be a monomeric protein with a molecular mass of ~75 kDa as...
