Decolorization of rhodamine B and congo red by partial purified laccase from Lentinus polychrous Lév
This study reports decolorization of Rhodamine B and Congo red by a partially purified laccase from Lentinus polychrous Lév. in the presence or absence of 2,2-azinobis (3-ethylbenzothiazoline-6sulfonate) diammonium salt (ABTS) as a redox mediator. The decolorization study showed that about 90% of Rhodamine B could be decolorized within 52 h, whereas Congo red could be decolorized more than 75% ...
متن کاملDecolorization of Solophenyl Red 3BL Polyazo Dye by Laccase-Mediator System: Optimization through Response Surface Methodology
The decolorization of direct Solophenyl red 3BL (SR), a polyazo dye extensively used in textile industry was studied. The Fomes fomentarius laccase alone did not decolorize SR. The natural redox mediator, acetosyringone (AS), was necessary for decolorization to occur. Box-Behnken design was used to evaluate the effects of three parameters, namely, enzyme concentration (0.5-2.5 U mL(-1)), redox ...
متن کاملSimple fabrication of polymer-based Trametes versicolor laccase for decolorization of malachite green.
A highly efficient and stable biocatalyst (denoted D201_Lac) was fabricated by encapsulating Trametes versicolor laccase within a macroporous and strongly basic exchange resin D201 through a simple adsorption process. Transmission electron micrographs and Fourier transform infrared spectra of the resultant D201_Lac proved that nanosized laccase clusters were embedded into the inner nano-pores/c...
متن کاملRole of Laccase and Low Molecular Weight Metabolites from Trametes versicolor in Dye Decolorization
The studies regarding decolorization of dyes by laccase may not only inform about the possible application of this enzyme for environmental purposes, but also may provide important information about its reaction mechanism and the influence of several factors that could be involved. In this paper, decolorization of crystal violet and phenol red was carried out with different fractions of extrace...
متن کاملDye Decolorization using Fungal Laccase
The increasing use of synthetic dyes is alarming and their discharge as textile waste may cause substantial ecological damage. Biological decolorization of dye using microorganisms is an environmentally friendly and costcompetitive alternative to chemical methods. This study involves the application of laccase obtained from Pleurotus ostreatus, a common fungus, in decolorization and degradation...
