“…However, the loss of activity by enzymes in the process of their use is a serious problem. In this regard, the use of immobilized forms of enzymes capable of catalyzing the degradation of various PCPs was studied ( Table 2 ) [ 8 , 11 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 ].…”

“…At the same time, high energy costs are required to remove PCPs by this method from the total volume of treated wastewater. A study of the purification of municipal wastewater from triclosan using electrochemical processes in combination with treatment by laccase immobilized on TiO 2 nanoparticles showed that the degradation efficiency of triclosan reached 93% [ 30 ]. The TiO 2 nanoparticles used for such immobilization are characterized by high chemical stability and simplicity of functionalization, for which crosslinking agents can be applied [ 36 ].…”

The review focuses on the appearance of various pharmaceutical pollutants in various water sources, which dictates the need to use various methods for effective purification and biodegradation of the compounds. The use of various biological catalysts (enzymes and cells) is discussed as one of the progressive approaches to solving problems in this area. Antibiotics, hormones, pharmaceuticals containing halogen, nonsteroidal anti-inflammatory drugs, analgesics and antiepileptic drugs are among the substrates for the biocatalysts in water purification processes that can be carried out. The use of enzymes in soluble and immobilized forms as effective biocatalysts for the biodegradation of various pharmaceutical compounds (PCPs) has been analyzed. Various living cells (bacteria, fungi, microalgae) taken as separate cultures or components of natural or artificial consortia can be involved in biocatalytic processes under aerobic or anaerobic conditions. Cells as biocatalysts introduced into water treatment systems in suspended or immobilized form are used for deep biodegradation of PCPs. The potential of combinations of biocatalysts with physical–chemical methods of wastewater treatment is evaluated in relation to the effective removing of PCPs. The review analyzes recent results and the main current trends in the development of biocatalytic approaches to biodegradation of PCPs, the pros and cons of the processes and the biocatalysts used.

“…Removal percentage of >90% is mostly achieved by wastewater treatment using batch system. [16,19,[96][97][98][99]100] Meanwhile, systems employing filtration or continuous packed bed reactors have a tendency of obtaining relatively low contaminant removal, [21,101,102] especially when it comes to dyeing agents. [14,103] The supporting polymers could act synergistically entrapping the pollutant to their surface, hence the combination of adsorptive and enzymatic degradation-based removal.…”

Global threat from emerging contaminants to human health has pushed researchers to develop pollutant removal technologies including those based on biocatalytic degradation. Laccase, a multicopper enzyme, is reported for its applicability in treating wastewater and industrial effluent by catalyzing reduction of O 2 to H 2 O in the presence of substrates (phenolic or non-phenolic compounds). Scientific papers have discussed the ability of this enzyme to breakdown hazardous contaminants ranging from azo dyes, antibiotics, and up to hormones. Nonetheless, the cost production of this enzyme is high, hence the importance of the immobilization into solid supports. Polymers are considered suitable for the immobilization because they are easy for modification and have adjustable characteristics. This review discusses the immobilization of laccase into polymers via various techniques (adsorption, cross-linking, covalent binding, encapsulation, and entrapment) and its implications on the pollutant removal performance. In addition, bibliometric analysis is performed and summarized the advantages and disadvantages of each immobilization technique.

An expanding number of human activities are contributing to the rising levels of aromatic compounds, which pose a major threat to the ecosystem. However, readily available microbial enzymes might be used to remediate contaminated wastewater in an economical and environmentally benign manner. In this study, an efficient method of laccase-oriented immobilization on modified Immobead 150P was proposed. The oriented immobilization technique using aminated laccase exceeds in both protein loading onto the carrier (4.26 mg/g) and immobilization yield (93.57%) due to the availability of more active sites. The oriented aminated laccase preserves 100% and 95% of its original activity after six and ten cycles of operation, respectively. The thermal stability performance of the oriented enzyme was the best among both free and random immobilized forms, since it was able to conserve 79% and 44% of its initial activity after 6 h at 50 °C and 60 °C, respectively. The ideal pH of oriented immobilized laccase was altered from 3.0 to 4.0, and it was more stable than both free and random immobilized laccases at pH 7.0. Finally, the integration of the adsorption capacity of Immobead 150P and the biodegradation ability of laccase promises the efficient removal of aqueous phenolics. Oriented immobilized laccase may provide a significant new approach for wastewater treatment, according to these findings.
