Abstract Laccase, a blue multicopper oxidase, has recently received considerable attention because of its usefulness in oxidizing phenolic and non‐phenolic compounds, as well suitability for organic synthesis, environmental pollutant treatment, other biotechnological applications. This review covers recent studies on the structural properties, occurrence, reaction mechnisms, redox mediators laccases their application synthesis procedures, such dimerization, polymerization, oxidation,...
Alginate-gelatin mixed gel was applied to immobilized laccase for decolorization of some synthetic dyes including crystal violet. The immobilization procedure accomplished by adding alginate a gelatin solution containing the enzyme and subsequent dropwise addition mixture into stirred CaCl 2 solution. obtained data showed that both free enzymes acted optimally at 50°C removal violet, but entrapped higher thermal stability compared enzyme. represented optimum pH 8. Reusability also studied...
Enzymatic elimination of synthetic dyes, one the most environmentally hazardous chemicals, has gained a great interest during two last decades. The present study was performed to evaluate decolorization and detoxification potential purified laccase Paraconiothyrium variabile in both non-assisted hydroxybenzotriazole-aided form against six azo dyes.The obtained results showed that Acid Orange 67, Disperse Yellow 79, Basic 28, Red 18, Direct 107, Black 166 were decolorized up 65.3, 53.3, 46.7,...
Abstract The design of reusable high‐performance heterogeneous catalysts via the immobilization chemical and biochemical species on magnetic nanoparticles increases efficiency catalytic systems by facilitating easy, fast, clean separation processes. Laccase 4‐amino‐2,2,6,6‐tetramethylpiperidine‐1‐oxyl were separately immobilized amine functionalized iron (II, III) oxide with covalent bonding using glutaraldehyde as a coupling reagent. prepared catalyst was used to synthesize 12 benzoxazole...
Green cascade approaches, which utilize sustainable and recyclable heterogeneous biocatalysts, can be used in the catalysis of multicomponent organic reactions to synthesize biologically important substances. Three magnetic nanoparticles, iron (II, III) oxide, cobalt ferrite, nickel were prepared by co‐precipitation functionalized with fibrous silica (KCC‐1), characterized scanning electron microscopy (SEM), X‐ray diffraction (XRD), vibrating sample magnetometry (VSM). Laccase immobilized on...
In recent years, enzymatic-assisted removal of hazardous dyes has been considered as an alternative and eco-friendly method compared to those physicochemical techniques. The present study was designed in order obtain the optimal condition for laccase-mediated (purified from ascomycete Paraconiothyrium variabile) decolorization Acid Blue 92; a monoazo dye, using response surface methodology (RSM). So, D-optimal design with three variables, including pH, enzyme activity, dye concentration,...
Abstract Co‐immobilization of bio‐ and chemocatalysts produces sustainable, recyclable hybrid systems that open new horizons for green cascade approaches in organic synthesis. Here, the co‐immobilization laccase 2,2,6,6‐tetramethylpiperidin‐1‐oxyl (TEMPO) mesoporous silica was used one‐pot aqueous synthesis 30 coumarin‐3‐carboxylate derivatives under mild conditions through condensation situ oxidized 2‐hydroxybenzyl alcohols malonate derivatives. A maximum yield obtained after incubating at...
A heterogeneous biocatalyst composed of laccase immobilized on Fe3O4 magnetic nanoparticles was prepared via a click chemistry reaction for dimerization phenylacetylene. The physical and chemical characteristics the catalyst were investigated. Yield efficiency immobilization 68.7% 76.4%, respectively. apparent Km value 1.5-fold greater than free enzyme, calculated Vmax 65 mM min‒1 43 min‒1, While enzyme completely lost its activity, more 60% initial activity conserved after 30 days....
Various proteins and enzymes produced during algal photosynthesis can be used in economic development environment management, such as wastewater treatment, production of fine chemicals, biodiesel production. This mini-review presents various isolated from algae suggests that algae, given their unique properties, could explored for large-scale future biocatalyst factories.HighlightsVarious are photosynthesis.Algae use phosphoglycolate phosphatase glycolate oxidase metabolizing enzymes.Algae...
