Decolorization of two synthetic dyes using the purified laccase of Paraconiothyrium variabile immobilized on porous silica beads
BACKGROUND Decolorization of hazardous synthetic dyes using laccases in both free and immobilized form has gained attention during the last decades. The present study was designed to prepare immobilized laccase (purified from Paraconiothyrium variabile) on porous silica beads followed by evaluation of both free and immobilized laccases for decolorization of two synthetic dyes of Acid Blue 25 an...
متن کاملImmobilization of Laccase in Alginate-Gelatin Mixed Gel and Decolorization of Synthetic Dyes
Alginate-gelatin mixed gel was applied to immobilized laccase for decolorization of some synthetic dyes including crystal violet. The immobilization procedure was accomplished by adding alginate to a gelatin solution containing the enzyme and the subsequent dropwise addition of the mixture into a stirred CaCl(2) solution. The obtained data showed that both immobilized and free enzymes acted opt...
متن کاملDecolorization of reactive dyes by laccase immobilized in alginate/gelatin blent with PEG.
To achieve effective decolorization of reactive dyes, laccase immobilization was investigated. Laccase 0.2% (m/V) (Denilite IIS) was trapped in beads of alginate/gelatin blent with polyethylene glycol (PEG), and then the supporters were activated by cross-linking with glutaraldehyde. The results of repeated batch decolorization showed that gelatin and appropriate concentration of glutaraldehyde...
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 کاملCharacterization and Decolorization of Dye and Textile Effluent by Laccase from Pleurotus Florida- a White-rot Fungi
The textile industries by for the most passionate user of synthetic dyes are in need of ecoefficient solutions for its coloured effluents. The decolorization and detoxification potential of white rot fungi can be harnessed. Laccase has been utilized in biological treatment of effluents containing chemical dyes. The present study is planned to study the screening and chrecterization of laccase f...
