Immobilization of laccase on a novel ZnO/SiO₂nano-composited support for dye decolorization

Synergistic Degradation of Dye Wastewaters Using Binary or Ternary Oxide Systems with Immobilized Laccase

“…This is governed by the presence of SiO 2 in a three-component material. The addition of silica increases the efficiency of the immobilization of laccase on the carrier, which leads to an increase in the efficiency of the removal of Alizarin Red S dye [39]. These results are in agreement with a study by Li et al, who immobilized laccase onto ZnO/SiO 2 material and degraded Remazol Brilliant Blue B and Acid Blue 25 from an aqueous solution at a concentration 0.1 mol/L.…”

Applications and immobilization strategies of the copper-centred laccase enzyme; a review

“…With the stringent regulations and restrictions established for effluent discharge into the ecosystem, a number of studies have focused on microorganisms, which are able to decolourise and biodegrade these dyes [ 239 , 240 , 241 , 242 ]. Enzymatic treatment of dye effluents has gained attention because of the mild reaction conditions involved without generating any secondary pollution like toxic sludge [ 243 , 244 ].…”

“…Composites consisting of two or more nanomaterials have also been studied for laccase immobilization. For example, Poly (hydroxyethyl methacrylate-N-methacryloly-(l)-histidinemethylester)-copper (II) [PHEMAH-Cu 2+ ] nanospheres [ 398 ], TiO 2 -Montmorillonite (MT) complexes [ 385 ], Fe 3 O 4 /SiO 2 nanoparticles [ 230 , 231 ], Polyacrylonitrile-biochar composite nanofibrous membrane [ 180 ], SWNT/nanocrystalline carbon quantum dots [ 336 ], CS/PVA composite nanofibrous membranes [ 191 ], ZnO/SiO 2 nano-composited [ 243 ], Zinc tetraaminophthalocyanine-Fe 3 O 4 nanoparticle composite [ 394 ], and copper tetra-aminophthalocyanine (CuTAPc)-Fe 3 O 4 [ 296 , 392 , 603 ].…”

Immobilization of Rhus vernicifera laccase on sepiolite; effect of chitosan and copper modification on laccase adsorption and activity

“…Most laccase-complexes have an isoelectric point of pH ~ 4 (Baldrian, 2006;Viswanath 157 et al, 2014), and indeed, some studies specify a negative surface charge (Li et al, 2015).…”
