Abstract
Herein, a highly efficient and recyclable biocatalyst was developed using stabilized enzyme aggregates on amino-functionalized magnetic biochar for removing persistent organic pollutants from water. The biochar derived from biomass featured abundant hydroxyl functional groups, after functionalization with amino functional groups and magnetic nanoparticles, it was employed for laccase immobilization via enzyme electrostatic adsorption, precipitation and cross-linking in a favorable orientation. This immobilized enzyme aggregates exhibited enhanced pH tolerance, thermal and storage stability than free enzyme. Complete removal of 20 mg/L bisphenol A was achieved within 60 min via C-C bond cleavage and hydroxylation. Notably, the removal efficiency remained at approximately 90 % even after six cycles. Furthermore, this biocatalyst was also successfully applied to efficiently remove other various persistent organic pollutants and demonstrated applicability in real environmental water samples. This study highlights the substantial potential of enzyme-based biocatalysts, presenting a sustainable and efficient approach for water purification and biomass resource recovery.

Abstract
OBJECTIVE Lignocellulosic biomass contains both nitrogen and carbon resources, make it ideal substrate for microbial development and the production of enzymes. METHODS The current research emphasizes producing and optimizing the laccase enzyme from lignocellulosic wastes utilizing Aspergillus oryzae under solid-state fermentation. The optimal laccase production conditions have been identified, and the obtained enzyme was assessed for cytotoxicity, therapeutic benefits on breast tumors (MDA-MB-231), and 4-chlorophenol (4-CP) degradation. Initially, RSM (Response Surface Method) was used to enhance physio-chemical factors as moisture, temperature, pH, carbon and nitrogen sources, and copper sulfate (CuSO4) levels. Aspergillus oryzae showed the highest laccase production (430.73 U/mL) using corn straw with 1.0 % xylose and yeast extract, 0.5 mM CuSO4, 80 % moisture content, temperature 30 °C, and pH 7.0. Furthermore, the isolated enzyme laccase has been shown to have a strong killing activity against tumor cells (MDA-MB-231). RESULTS Laccase showed an IC50 value of 16.17 % when treated with the cells of MDA-MB-231 at 100 μM/mL. The enzyme caused apoptosis in cancer cells also greatly increased DNA damage in tumor cell types. In addition, the laccase enzyme successfully decomposed 4-CP by 68.56 % within 72 h. CONCLUSION The current research shows that using corn straw with SSF provides both waste treatment and production of enzymes in an environmentally benign and economically viable manner. Laccase has the potential for use in innovative enzymatic treatment and bioremediation applications.

Abstract
Biodegradable and sustainable materials utilized for laccase immobilization have garnered substantial scholarly interest owing to their capacity to enhance enzyme stability and reusability, which are paramount for effective bioremediation methodologies. Laccase, a versatile oxidase, possesses the ability to degrade a broad spectrum of environmental contaminants, thus rendering it an invaluable asset in bioremediation endeavours. The immobilization of laccase onto biodegradable substrates not only augments its operational stability but also resonates with sustainable environmental strategies. This article systematically investigates recent advancements in sustainable and eco-conscious methodologies aimed at immobilizing laccase. By integrating biodegradable and non-toxic components, we elucidated how these materials not only proficiently enhanced the operational stability of laccases, but also improved their biodegradation effectiveness. A comprehensive analysis revealed that these sustainable materials facilitate immobilized laccase-mediated efficient removal of hazardous chemicals. Furthermore, we highlight the challenges that persist despite the encouraging characteristics of sustainable and eco-friendly approaches to laccase immobilization and pollutant elimination, and engage in discourse regarding potential pathways for their broader application and scalable solutions. This review highlights the significance of incorporating green technologies into environmental remediation efforts, thereby fostering the development of more effective and ecologically sound solutions for sustainable laccase immobilization to mitigate environmental contaminants efficiently.

Abstract
Facing the combined pollution of antibiotics and heavy metals caused by livestock excrement and industrial effluents, how to use microbial technology to remove these pollutants simultaneously is an important research topic in environmental remediation. In addition, quick separation of the bacteria-water after remediation is also an urgent problem. In this study, we gradually developed a dual-bacteria microbial treatment technology capable of removing Pb(Ⅱ), Cd(Ⅱ) and common antibiotics, as well as self-settling after treatment. The key technology in this study mainly includes modifying the bacterial membrane proteins using Pb-binding protein PbrR, Cd-binding protein CadR and bacterial laccase CotA via surface-display technology to maximize the removal of Pb(Ⅱ), Cd(Ⅱ) and antibiotics, separately. Besides, the introduction of nanobody-antigen adhesion facilitated the self-settling in dual-bacterial system. Then, we studied its effectiveness in removing single pollutants, analyzed the influence of different heavy metal ions, and conducted detailed studies on the kinetics. Further characterization of heavy metal biosorption behavior was conducted using SEM, SEM-EDS, FTIR, and XPS techniques. Via protein fusion and dual vector expression, we constructed a dual-bacteria treatment system that could achieve rapid, selective removal of combined pollutants at a wide pH range temperature range, ultimately precipitating at bottom. Finally, molecular dynamics simulation was employed to elucidate the molecular mechanism underlying the selective biosorption by metal-binding proteins. The findings in this study hold significant implications for achieving selective pollutant removal using engineering bacteria in complex water environments.

JOURNAL OF HAZARDOUS MATERIALS 2025; 485:136803. [PMID: 39672062 DOI: 10.1016/j.jhazmat.2024.136803] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/02/2024] [Revised: 12/03/2024] [Accepted: 12/04/2024] [Indexed: 12/15/2024]
Abstract
The outflow of pharmaceutically active chemicals (PhACs) exerts a negative impact on biological systems even at extremely low concentrations. For instance, enormous threats to human and aquatic species have resulted from the widespread use of antibiotics in ecosystems, which stimulate the emergence and formation of antibiotic-resistant bacterial species and associated genes. Additionally, it is challenging to eliminate these PhACs by employing conventional physicochemical water treatment techniques. Enzymatic approaches, including laccase, have been identified as a promising alternative to eliminate a broad array of PhACs from water matrices. However, their application in environmental bioremediation is hindered by several factors, including the enzyme's stability and its location in the aqueous environment. Such obstacles may be surmounted by employing laccase immobilization, which enables enhanced stability (including inactivation caused by the substrate), and thus improved catalysis. This review emphasizes the potential hazards of PhACs to aquatic organisms within the detection concentration range of ngL-1 to µgL-1, as well as the deployment of laccase-based multifunctional biocatalytic systems for the environmentally friendly mitigation of anticancer drugs, analgesics/NSAIDs, antibiotics, antiepileptic agents, and beta blockers as micropollutants. This approach could reduce the underlying toxicological consequences. In addition, current developments, potential applications, and viewpoints have focused on computer-assisted investigations of laccase-PhACs binding at enzyme cavities and degradability prediction.

Abstract
The environmental persistence of pharmaceuticals represents a significant threat to aquatic ecosystems and human health, while limitations in conventional wastewater treatment methods underscore the urgent need for innovative and eco-friendly degradation strategies. Photobiocatalytic approaches provide a promising solution for the effective degradation of pharmaceutical contaminants by harnessing the synergistic effects of both photocatalysts and biocatalysts. In this study, we developed a photobiocatalytic composite by co-immobilizing laccase enzyme and zinc oxide nanoparticles on bacterial cellulose synthesized from orange peel waste. The optimal conditions for achieving maximum yield and efficiency of immobilization were investigated and the successful preparation of the composite was confirmed using infrared spectroscopy, X-ray diffraction, and scanning electron microscopy. The immobilized laccase showed Km and Vmax values of 0.68 ± 0.23 mM and 5.4 ± 0.86 μmol/min/L, respectively. The prepared composite was efficiently applied for degradation of favipiravir under optimum conditions including pH, temperature, and incubation time values of 4.0, 50 °C, and 90 min, respectively. The presence of ZnO nanoparticles in the structure of the photobiocatalyst significantly decreased the time of removal in comparison with both free and immobilized laccases. Although 80 ± 5.5 % of the enzyme activity was kept after 10 runs, the prepared photobiocatalyst retained 50 ± 4.6 % of its initial activity after 10 independent cycles. The study showed that the synergistic effects of laccase and ZnO nanoparticles possess the potentials to enhance degradation efficiency through combined light-driven and enzymatic approaches.

Abstract
Bioremediation of trichloroethylene (TCE) contaminated groundwater has recently attracted considerable attention. In this study, laccase was immobilized on amino modified magnetic pine biochar (MBC-NH2) by adsorption-crosslinking-covalent binding method, and its application in the degradation of TCE was evaluated. MBC-NH2 was obtained from pine sawdust by calcination, magnetic modification and amino modification. MBC-NH2 had high specific surface area (71.3 m2/g), rich surface functional groups and good magnetism. Under the conditions of 25 °C, pH = 4, glutaraldehyde (GA) concentration of 7 %, crosslinking time of 1 h, laccase concentration of 0.75 mg/mL, and immobilization time of 7 h, the loading capacity of laccase on MBC-NH2 carrier was as high as 782 mg/g. Compared with free laccase, immobilized laccase showed higher pH stability and thermal stability, and its activity remained 48.5 % after being reused for 10 times, and 80.8 % after being stored at 4 °C for 30 days. The immobilized laccase exhibited a good degradation effect on TCE. At 25 °C, pH = 4, immobilized laccase concentration of 0.35 g/L, and initial TCE concentration of 10 mg/L, the degradation efficiency of TCE by immobilized laccase was as high as 92.1 % within 48 h. In addition, the degradation products of TCE were analyzed, and the results showed that immobilized laccase could degrade TCE into non-toxic products through epoxidation, hydroxylation, and dechlorination. The immobilized laccase biocatalyst prepared in this study can achieve efficient degradation of TCE, which provides a feasible solution for chlorinated pollution of water resources. These research results are of great significance for the synthesis of biocatalysts for the efficient degradation of chlorinated hydrocarbons.

Abstract
Laccases with highly catalytic properties have been widely used in developing green applications for water remediation. However, the poor stability and low reutilization rate of free laccase make it difficult to be applied practically. Hence, in this study, an immobilized laccase was prepared using dopamine (DA) functionalized sodium alginate (SA)/polyethylene glycol (PEG) composite hydrogels to realize the recyclability of the laccase. The SA/PEG composite hydrogels, as the protective carrier for laccase, exhibited excellent catalytic stability in various interfering environments. After 30 days, Lac@SA-PDA/PEG beads could remain 70.23 % of the initial activity, as the residual activity of free laccase was only 12.35 %. When free laccase and Lac@SA-PDA/PEG beads were used for decolorization of Reactive Blue 19 (RB-19,100 mg/L), the degradation rate of Lac@SA-PDA/PEG is 6.88 times higher than free laccase. More importantly, the SA-PDA/PEG composite hydrogel exhibited a high reutilization rate, which after six cycles, Lac@SA-PDA/PEG beads retained 90.23 % of its initial activity. Besides, the degradation effect of Lac@SA-PDA/PEG on different dyes was analyzed. In addition, the conjectured degradation pathways of RB-19 by laccase were analyzed. The work showed that immobilized laccase has tremendous potential for the treatment of dyestuff wastewater.

Abstract
Water and wastewater pollution by acetamiprid and diuron is considered a serious environmental problem. In this study, chitosan (CHS), a naturally occurring bioadsorbent considered ecologically harmless to remove these micropollutants, was developed as a possible carrier to immobilize laccase (Lac) from Trametes trogii. Polyethylene glycol methyl ether (PEGME) was chosen for blending CHS, so a hybrid biocatalyst-based Lac/CHS-PEGME membrane was prepared. The prepared CHS-PEGME and Lac/CHS-PEGME membranes were characterized by Fourier-transformed-infrared (FTIR) spectroscopy, scanning-electron-microscopy (SEM), and X-ray-diffraction (XRD). Pesticide degradation tests with Lac/CHS-PEGME were performed at different contact times and initial concentrations. Acetamiprid degradation was most effective (84 %) at the 12th hour, at an initial concentration of 0.1 mg/L, while diuron degradation was most effective (65 %) at an initial concentration of 6 mg/L and a contact time of 16th hour. Under optimum conditions, the reusability of Lac/CHS-PEGME was found to be 8 cycles for acetamiprid and 5 cycles for diuron. From these results, it is understood that acetamiprid is degraded more quickly and effectively than diuron. Adsorption process data were well fitted to the Langmuir isotherm model and the pseudo-first-order kinetic model. These findings showed that using Lac/CHS-PEGME was a practical and environmentally friendly method for acetamiprid and diuron degradation.

Abstract
Polycyclic aromatic hydrocarbons (PAHs) are widespread, persistent, and toxic environmental pollutants. Many anthropogenic and some natural factors contribute to the spread and accumulation of PAHs in aquatic and soil systems. The effective and environmentally friendly remediation of these chemical compounds is an important and challenging problem that has kept scientists busy over the last few decades. This review briefly summarizes data on the main sources of PAHs, their toxicity to living organisms, and physical and chemical approaches to the remediation of PAHs. The basic idea behind existing approaches to the bioremediation of PAHs is outlined with an emphasis on a detailed description of the use of bacterial strains as individual isolates, consortia, or cell-free enzymatic agents.

Abstract
The use of nanocatalytic particles for the removal of refractory organics from wastewater is a rapidly growing area of environmental purification. However, little has been done to investigate the effects of nanoparticles on soil-plant systems with antibiotic contamination. This work assessed the effect of molybdenum disulfide (MoS2) on the soil-Phragmites communis system containing levofloxacin (LVX). The results showed that the addition of MoS2 had restoration potential for stressed plant. The MoS2 with catalytic activity promoted the transformation of LVX in rhizosphere soils. The transformation pathways of LVX in the different exposure groups were proposed. The continuous output of radicals in the high MoS2 dosage group facilitated the transformation of LVX to small molecule compounds, which were eventually mineralized. Moreover, the electron-density-difference analysis revealed the easier flow of electrons from the MoS2 surface towards the LVX molecules. This finding provides theoretical support for the application of nanocatalytic particles in ecological environments.

Abstract
As a typical sulfonylurea herbicide, nicosulfuron is mainly used to control grass weeds and some broadleaf weeds in corn fields. However, as the amount of use continues to increase, it accumulates in the environment and eventually becomes harmful to the ecosystem. In the present study, a new metallic nanomaterial, δ-MnO2, was prepared, which not only has a similar catalytic mechanism as laccase but also has a significant effect on pesticide degradation. Therefore, the bicatalytic property of MnO2 can be utilized to improve the remediation of nicosulfuron contamination. Firstly, MnO2 nanomaterials were prepared by controlling the hydrothermal reaction conditions, and immobilized laccase was prepared by the adsorption method. Next, we investigate the effects of different influencing factors on the effect of immobilized laccase, MnO2, and free laccase on the degradation of nicosulfuron in water and soil. In addition, we also analyze the metabolic pathway of nicosulfuron degradation in immobilized laccase and the bicatalytic mechanism of MnO2. The results demonstrated that the degradation rate of nicosulfuron in water by immobilized laccase was 88.7%, and the optimal conditions were 50 mg/L, 25 h, 50 °C, and pH 5. For nicosulfuron in soil, the optimal conditions for the degradation by immobilized laccase were found to be 151.1 mg/kg, 46 °C, and pH 5.9; under these conditions, a degradation rate of 90.1% was attained. The findings of this study provide a theoretical reference for the immobilized laccase treatment of sulfonylurea herbicide contamination in water and soil.

BIORESOURCE TECHNOLOGY 2024; 406:131072. [PMID: 38971387 DOI: 10.1016/j.biortech.2024.131072] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/01/2024] [Revised: 06/27/2024] [Accepted: 07/03/2024] [Indexed: 07/08/2024]
Abstract
Immobilized laccases are widely used as green biocatalysts for bioremediation of phenolic pollutants and wastewater treatment. Metal-organic frameworks (MOFs) show potential application for immobilization of laccase. Their unique adsorption properties provide a synergic effect of adsorption and biodegradation. This review focuses on bioremediation of wastewater pollutants using laccase-MOF composites, and summarizes the current knowledge and future perspective of their biodegradation and the enhancement strategies of enzyme immobilization. Mechanistic strategies of preparation of laccase-MOF composites were mainly investigated via physical adsorption, chemical binding, and de novo/co-precipitation approaches. The influence of architecture of MOFs on the efficiency of immobilization and bioremediation were discussed. Moreover, as sustainable technology, the integration of laccases and MOFs into wastewater treatment processes represents a promising approach to address the challenges posed by industrial pollution. The MOF-laccase composites can be promising and reliable alternative to conventional techniques for the treatment of wastewaters containing pharmaceuticals, dyes, and phenolic compounds. The detailed exploration of various immobilization techniques and the influence of MOF architecture on performance provides valuable insights for optimizing these composites, paving the way for future advancements in environmental biotechnology. The findings of this research have the potential to influence industrial wastewater treatment and promoting cleaner treatment processes and contributing to sustainability efforts.
