“…It has been shown that direct addition of those enzymes to P&P mill effluent can facilitate the degradation of lignin species (Hakulinen 1988;Wagner and Nicell 2001;Fernandez-Fernandez et al 2013;Hossain and Ismail 2015;Kurnik et al 2015). Ko and Fan (2010) showed the feasibility of a two-step process in which laccase enzyme was used to polymerize ligninbased compounds and then the mixture was separated using membranes with a range of different pores sizes.…”

“…One possible motivation for isolation and use of pure enzymes might be related to the possibility of immobilization (Duran and Esposito 2000). As noted by Fernandez-Fernandez et al (2013), immobilization of enzymes can improve their storage stability and prolong their effectiveness during wastewater treatment. On the other hand, it is also possible to immobilize the fungal organisms on a suitable support and generate the needed enzymes in-situ (Marwaha et al 1998;Taseli and Gökçay 1999;Wesenberg et al 2003;Wu et al 2005;Malaviya and Rathore 2007).…”

The pulp and paper (P&P) industry worldwide has achieved substantial progress in treating both process water and wastewater, thus limiting the discharge of pollutants to receiving waters. This review covers a variety of wastewater treatment methods, which provide P&P companies with costeffective ways to limit the release of biological or chemical oxygen demand, toxicity, solids, color, and other indicators of pollutant load. Conventional wastewater treatment systems, often comprising primary clarification followed by activated sludge processes, have been widely implemented in the P&P industry. Higher levels of pollutant removal can be achieved by supplementary treatments, which can include anaerobic biological stages, advanced oxidation processes, bioreactors, and membrane filtration technologies. Improvements in the performance of wastewater treatment operations often can be achieved by effective measurement technologies and by strategic addition of agents including coagulants, flocculants, filter aids, and optimized fungal or bacterial cultures. In addition, P&P mills can implement upstream process changes, including dissolved-air-flotation (DAF) systems, filtration save-alls, and kidney-like operations to purify process waters, thus reducing the load of pollutants and the volume of effluent being discharged to end-of-pipe wastewater treatment plants.

On the positive side, the industry is based on the usage of renewable, photosynthetic resources. On the other hand, the industry discharges huge quantities of aqueous effluents. Large volumes (up to 70 m 3 ) of wastewater ...

“…Various methods concerning laccase immobilization have been reported, including entrapment, encapsulation, adsorption, covalent binding, as well as self-immobilization [9]. Among all these methods, adsorption is relatively simple and less expensive, so it may have a higher commercial potential than the other methodologies.…”

Abstract:In this work, amidoxime polyacrylonitrile (AOPAN) nanofibrous membrane was prepared by a reaction between PAN nanofibers and hydroxylamine hydrochloride. The AOPAN nanofibrous membranes were used for four metal ions (Fe ) and also the four mixed metal ions were further used for laccase (Lac) immobilization. Compared with free laccase, the immobilized laccase showed better resistance to pH and temperature changes as well as improved storage stability. Among the four individual metal ion chelated membranes, the stability of the immobilized enzymes generally followed the order as Fe-AOPAN-Lac > Cu-AOPAN-Lac > Ni-AOPAN-Lac > Cd-AOPAN-Lac. In addition, the immobilized enzyme on the carrier of AOPAN chelated with four mixed metal ions showed the best properties.

“…6 Owing to their improved stability and storage ability, the immobilization of enzymes offers several advanced applications such as the system of enzyme is easier to operate, the enzyme can be reused, and the cost of the process reduced. 7 The reusability and the cost of immobilized enzymes constitute a great advantage over free enzymes. 8 In an immobilization study, the most crucial point is to immobilize a bioactive reagent onto a support bearing a functional group on the surface.…”

Poly(MA-alt-MVE)-g -PLA/ODA-MMT nanocomposite was prepared by self-catalytic interlamellar graft copolymerization of L-lactic acid (LA) onto poly(maleic anhydride-alt-methyl vinyl ether) copolymer in the presence of octadecyl amine-montmorillonite (ODA-MMT) organoclay. FTIR, 1 H ( 13 C) NMR, XRD, and SEM-TEM were utilized for characterizing the resultant nanocomposite. Laccase from Trametes versicolor was immobilized onto the prepared nanocomposite by adsorption or covalent coupling. Decolorization of Reactive Red 3 from aqueous solution by laccase immobilized on the nanocomposite was studied in different conditions (pH, temperature, dye concentration, and reaction time) to investigate the decolorization activity with repeated use and storage. The results indicated that more than 77% of the activity of laccase immobilized systems was retained at the end of 10 cycles. The final decolorization capacity of the immobilized laccase was significantly higher (65%) than that of free laccase (33%) in the chosen optimized conditions (pH 5, 20 • C, 0.05 mg/mL laccase concentration, and 90 min).
