Non-isothermal bioremediation of waters polluted by phenol and some of its derivatives by laccase covalently immobilized on polypropylene membranes

Biodegradation of Phenol and Phenolic Derivatives by a Mixture of Immobilized Cells ofAspergillus AwamoriandTrichosporon Cutaneum

“…it should be noted that the substituted phenolic derivatives with chlorine atoms in ortho-position are more susceptible to oxidation and those at para-and meta-position have low reactivity (17). other authors report that some microorganisms prefer to biodegrade chlorine derivatives in meta-position to the derivatives in para-and ortho-position (14,16).…”

Decolorization of Synthetic Dyes by Crude Laccase from Lentinus Polychrous Lev.

“…Laccase is a multi copper oxidase and be capable of catalyzing the oxidation of a wide range of phenolic compounds and aromatic amines through the reduction of molecular di-oxygen to water [5]. Due to their ability to oxidize broad substrates, laccases have been extensively applied in several fields, such as decolorization of dyes, degradation of xenobiotics, pulp and paper industry, denim bleaching, food industry and organic synthesis.…”

Immobilization of β-galactosidase on modified polypropilene membranes

“…Ethylenediamine and GA were used as a spacer and bifunctional agent respectively. Laccase from Trametes versicolor [16] was covalently immobilized on chemically modified PP membrane and used for remove of phenol derivatives.…”
