Synthetic dye decolorization by three sources of fungal laccase
Decolorization of six synthetic dyes using three sources of fungal laccase with the origin of Aspergillus oryzae, Trametes versicolor, and Paraconiothyrium variabile was investigated. Among them, the enzyme from P. variabile was the most efficient which decolorized bromophenol blue (100%), commassie brilliant blue (91%), panseu-S (56%), Rimazol brilliant blue R (RBBR; 47%), Congo red (18.5%), a...
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...
متن کاملFactorial design for optimization of laccase production from Pleurotus ostreatus IMI 395545 and laccase mediated synthetic dye decolorization
In the present study, Plackett–Burman design (PBD) followed by response surface methodology (RSM) was used to optimize the culture medium composition for laccase production from Pleurotus ostreatus IMI 395545. Influence of carbon, nitrogen (sources) and inducer were evaluated by Plackett–Burman design. The factors that induce positive effect on enzyme production were further optimized using cen...
متن کاملImmobilized laccase mediated dye decolorization and transformation pathway of azo dye acid red 27
BACKGROUND Laccases have good potential as bioremediating agents and can be used continuously in the immobilized form like many other enzymes. METHODS In the present study, laccase from Cyathus bulleri was immobilized by entrapment in Poly Vinyl Alcohol (PVA) beads cross-linked with either nitrate or boric acid. Immobilized laccase was used for dye decolorization in both batch and continuous ...
متن کاملUse of sugarcane molasses by Pycnoporus sanguineus for the production of laccase for dye decolorization.
Pycnoporus sanguineus is a white-rot basidiomycete that produces laccase as the only oxidoreductase; enzyme synthesis depends on cultivation variables, and fungal species and strain. Laccases have wide substrate specificity, oxidize a broad range of compounds, and show potential for use in dye decolorization. We evaluated laccase production in a recently isolated strain of P. sanguineus cultiva...
