Degradation of azo dyes by Trametes villosa laccase over long periods of oxidative conditions

Article Abstract:

Trametes villosa laccase is used for direct azo dye degradation, and the reaction products that accumulated after 72 h of incubation is analyzed. Liquid chromatography-mass spectrometry (LC-MS) analysis reveal the formation of phenolic compounds during the dye oxidation process as well as large amount of polymerized products that retain azo group integrity.

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

Article Abstract:

Immobilizing the enzyme laccase from Trametes hirsuta stabilizes it and makes is more resistant to enzyme inhibitors. Immobilized laccase detoxified anthraquinonic dyes by up to 80%. This enzyme system could be used to decolorize and detoxify effluents from textile mills and other industries that generate phenolic compounds.

A new alkali-thermostable azoreductase from Bacillus sp. strain SF

Article Abstract:

Stringent environmental regulations have necessitated the treatment and reuse of dyeing effluents. Several microorganisms have the potential for azo-dye degradation but very few strains can withstand the conditions of dyeing effluents in terms of temperature and pH.
