Dye 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 کاملIn situ laccase-assisted overdyeing of denim using flavonoids.
A laccase-mediated system for denim overdyeing using phenolic compounds was developed. Laccase from ascomycete Myceliophthora thermophila was able to oxidize phenolic compounds such as catechol and catechin and mediate their attachment to denim surfaces. Laccase-generated polymers gave rise to new coloration states from dark brown to green-yellow and replaced dyes in the overdyeing process. Pro...
متن کاملSynthetic 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 کاملDecolorization of industrial synthetic dyes using engineered Pseudomonas putida cells with surface-immobilized bacterial laccase
BACKGROUND Microbial laccases are highly useful in textile effluent dye biodegradation. However, the bioavailability of cellularly expressed or purified laccases in continuous operations is usually limited by mass transfer impediment or enzyme regeneration difficulty. Therefore, this study develops a regenerable bacterial surface-displaying system for industrial synthetic dye decolorization, an...
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...
