“…In this approach, large molecules could be degraded into smaller ones using different microorganisms such as bacteria, fungi, and algae (Unuofin et al, 2019). Among microorganisms that potentially can be implemented in biological treatment, fungal systems have been mostly studied due to their significant ability to degrade ECs (Viancelli et al, 2020). Another advantage of fungal treatment is the flexibility in carbon or energy sources due to the fact that EC removal is essentially the result of the secondary metabolic action of fungi (Harms et al, 2011;Touahar et al, 2014).…”

Τhe ligninolytic enzyme laccase has proved its potential for environmental applications. However, there is no documented industrial application of free laccase due to low stability, poor reusability, and high costs. Immobilization has been considered as a powerful technique to enhance laccase’s industrial potential. In this technology, appropriate support selection for laccase immobilization is a crucial step since the support could broadly affect the properties of the resulting catalyst system. Through the last decades, a large variety of inorganic, organic, and composite materials have been used in laccase immobilization. Among them, carbon-based materials have been explored as a support candidate for immobilization, due to their properties such as high porosity, high surface area, the existence of functional groups, and their highly aromatic structure. Carbon-based materials have also been used in culture media as supports, sources of nutrients, and inducers, for laccase production. This study aims to review the recent trends in laccase production, immobilization techniques, and essential support properties for enzyme immobilization. More specifically, this review analyzes and presents the significant benefits of carbon-based materials for their key role in laccase production and immobilization.

“…In the wastewater treatment sector, the oxidoreductase enzymes laccase (Lac) and peroxidase (POD), mainly obtained from fungi, have been explored for emerging pollutants degradation (Morsi et al, 2020;Viancelli et al, 2020), presenting competitive advantages as performance in mild environmental conditions, low aggressiveness to the environment, and high speci city (Abedi et al, 2011). However, it is essential to emphasize that there are some challenges considering enzymatic application in contaminants removal, mainly concerning the need to keep the reactions stable and favorable to obtain the maximum catalytic performance.…”

The occurrence of micropollutants in aqueous matrices has become a global concern and a challenge for wastewater treatment plants. Monitoring their toxicity has shown that these compounds, even at low concentrations, pose risks to human and environmental health. Therefore, our study aimed to prospect immobilization strategies for non-commercial oxidoreductase enzymes and insert them in the context of pollutant remediation. The enzymatic extract was obtained by submerged fermentation of the fungus Trichoderma koningiopsis in an alternative substrate, consisting of fresh microalgal biomass from the phycoremediation process. The immobilization efficiency of peroxidase (POD) was evaluated by monitoring the residual activity (RA) and the discoloration potential (DP) of a synthetic dye solution. Concomitantly, the catalytic properties of free POD were explored, and the most promising storage strategy to maintain the enzymatic activity was studied. Guaiacol peroxidase from T. koningiopsis expressed specific activity of up to 7801.1 U mg− 1 in the free form, showing stability when subjected to up 80°C in a pH range between 4.0–8.0. Furthermore, the bioproduct immobilized on magnetic nanoparticles expressed up to 688% RA and 100% DP. An increase in the RA of the enzyme, both in free and immobilized form, was also observe after storage for up to 8 months. The synthesized magnetic nanozymes showed good reusability, maintaining 13546.4 U mg− 1 after ten cycles and removing 93% of color in a second batch. Toxicological evaluation with Allium cepa indicated that the enzymatic process of color removal with immobilized POD, despite maintaining unwanted cytotoxic effects, was essential to eliminate genotoxic effects. In this sense, the immobilization processes of T. koningiopsis peroxidase presented in our work are promising for the enzyme market and for the wastewater treatment sector.
