“…Immobilized biocatalyst preserved >90% of its original BPA removal efficiency after four degradation cycles (Hou et al, 2014). Mokhtar et al (2019) designed polymer brushes functionalized novel hollow fiber membrane to host laccase for biodegradation of BPA. The radiation-induced graft polymerization was used to synthesize polymer brushes of glycidyl methacrylate using aminoethanol as the functional group to unfold polymer brushes for efficient multilayer laccase immobilization (Fig.…”

“…The radiation-induced graft polymerization was used to synthesize polymer brushes of glycidyl methacrylate using aminoethanol as the functional group to unfold polymer brushes for efficient multilayer laccase immobilization (Fig. 8) (Mokhtar et al, 2019). The as-prepared system substantially improved the stability of the immobilized laccase than free enzyme in methanol-containing solutions by means of aminoethanol hydroxyl groups.…”

“…It can be supposed that xenobiotics degradation mediated by laccase may be improved by the addition of small molecular redox mediators. For example, BPA oxidation by laccase in the presence of redox mediators, such as acetosyringone, 1-hydroxybenzotriazole (HBT), 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) and 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), has been described previously [ 35 , 36 , 37 , 38 ]. However, this significantly increases operation costs and can generate secondary contaminants.…”

Bisphenol (BPA) is a key ingredient in the production of epoxy resins and some types of plastics, which can be released into the environment and alter the endocrine systems of wildlife and humans. In this study, the ability of the fungus M. roridumIM 6482 to BPA elimination was investigated. LC-MS/MS analysis showed almost complete removal of BPA from the growth medium within 72 h of culturing. Products of BPA biotransformation were identified, and their estrogenic activity was found to be lower than that of the parent compound. Extracellular laccase activity was identified as the main mechanism of BPA elimination. It was observed that BPA induced oxidative stress in fungal cells manifested as the enhancement in ROS production, membranes permeability and lipids peroxidation. These oxidative stress markers were reduced after BPA biodegradation (72 h of culturing). Intracellular proteome analyses performed using 2-D electrophoresis and MALDI-TOF/TOF technique allowed identifying 69 proteins in a sample obtained from the BPA containing culture. There were mainly structural and regulator proteins but also oxidoreductive and antioxidative agents, such as superoxide dismutase and catalase. The obtained results broaden the knowledge on BPA elimination by microscopic fungi and may contribute to the development of BPA biodegradation methods.

“…In addition, laccases can catalyze the one-electron oxidation of various organic and inorganic substrates, including phenols, ketones, phosphates, ascorbates, amines, and lignin. Free laccases extracted from nature have the disadvantages of poor stability, a short lifespan, being difficult to recycle, and high cost, meaning it is generally difficult for them to tolerate harsh industrial processing conditions [ 8 , 9 , 10 ]. Researchers have mainly modified enzymes through protein engineering, non-covalent modification, chemical modification, and immobilization [ 11 , 12 , 13 ].…”

Mesoporous Polymeric Ionic Liquid via Confined Polymerization for Laccase Immobilization towards Efficient Degradation of Phenolic Pollutants

et al. 2023

Laccase immobilization is a promising method that can be used for the recyclable treatment of refractory phenolic pollutants (e.g., chlorophenols) under mild conditions, but the method is still hindered by the trade-off limits of supports in terms of their high specific surface area and rich functional groups. Herein, confined polymerization was applied to create abundant amino-functionalized polymeric ionic liquids (PILs) featuring a highly specific surface area and mesoporous structure for chemically immobilizing laccase. Benefiting from this strategy, the specific surface area of the as-synthesized PILs was significantly increased by 60-fold, from 5 to 302 m2/g. Further, a maximum activity recovery of 82% towards laccase was recorded. The tolerance and circulation of the immobilized laccase under harsh operating conditions were significantly improved, and the immobilized laccase retained more than 84% of its initial activity after 15 days. After 10 cycles, the immobilized laccase was still able to maintain 80% of its activity. Compared with the free laccase, the immobilized laccase exhibited enhanced stability in the biodegradation of 2,4-dichlorophenol (2,4-DCP), recording around 80% (seven cycles) efficiency. It is proposed that the synergistic effect between PILs and laccase plays an important role in the enhancement of stability and activity in phenolic pollutant degradation. This work provides a strategy for the development of synthetic methods for PILs and the improvement of immobilized laccase stability.
