“…One of the most effective families of enzymes for bioremediation purposes are Laccases, which belong to the multicopper oxidases and can catalyze the oxidation of various aromatic substrates. Accordingly, they have the ability to degrade compounds such as phenols, amines, and hydrolyzed poly-acrylamides [ 50 , 51 , 52 , 53 ].…”

The oil and gas industry generates large amounts of oil-derived effluents such as Heavy Crude Oil (HCO) in water (W) emulsions, which pose a significant remediation and recovery challenge due to their high stability and the presence of environmentally concerning compounds. Nanomaterials emerge as a suitable alternative for the recovery of such effluents, as they can separate them under mild conditions. Additionally, different biomolecules with bioremediation and interfacial capabilities have been explored to functionalize such nanomaterials to improve their performance even further. Here, we put forward the notion of combining these technologies for the simultaneous separation and treatment of O/W effluent emulsions by a novel co-immobilization approach where both OmpA (a biosurfactant) and Laccase (a remediation enzyme) were effectively immobilized on polyether amine (PEA)-modified magnetite nanoparticles (MNPs). The obtained bionanocompounds (i.e., MNP-PEA-OmpA, MNP-PEA-Laccase, and MNP-PEA-OmpA-Laccase) were successfully characterized via DLS, XRD, TEM, TGA, and FTIR. The demulsification of O/W emulsions was achieved by MNP-PEA-OmpA and MNP-PEA-OmpA-Laccase at 5000 ppm. This effect was further improved by applying an external magnetic field to approach HCO removal efficiencies of 81% and 88%, respectively. The degradation efficiencies with these two bionanocompounds reached levels of between 5% and 50% for the present compounds. Taken together, our results indicate that the developed nanoplatform holds significant promise for the efficient treatment of emulsified effluents from the oil and gas industry.

“…It had been reported that oxygenase was under the oxidoreductase group of enzymes and participated in oxidation of reduced substrates transferring oxygen from molecular oxygen (O2) employing FAD/NADH/NADPH as a co-substrate. These enzymes had a significant character in the metabolism of organic compounds as they increased their reactivity or solubility in water or brought about cleavage of the aromatic rings (Pandey et al, 2017). They also reported that oxygenases also mediated dehalogenation reaction of halogenated methane, ethane and ethylene in connection with multifunctional enzymes monooxygenases.…”

The objective of the review study was carried out from different research data to find out the innovative latest information on the waste water treatment in agro, industrial and municipal areas. From the review study, it has been noted that cellulase, peroxidage, lignage, tyrosinase, pactinase and amylase have been widely used for waste water treatment. Besides, microbial enzymes such as microbial dioxygenase, oxygenase, laccase, peroxidase, lipase, cellulase, protease and fungal laccase have been applied for the waste water treatment in industrial and municipal areas and found effective results. Different techniques of application have been discussed using different hydrolytic and microbial enzymes. Therefore it seems that enzymatic treatments keep a significant role in waste water treatment from agro-food processing industries having low cost of production and treatment management process.

“…Despite many advantages of enzymatic remediation, the high cost of catalytic enzymes, inability to reuse, possible conformational alterations, and enzyme activity loss under harsh environmental conditions (such as high temperatures, high/low pH values, and high ionic strength) are some of the challenges [ 12 , 24 ]. Many of these issues can be addressed by immobilizing enzyme onto different solid supports.…”

Immobilized Soybean Peroxidase Hybrid Biocatalysts for Efficient Degradation of Various Emerging Pollutants

In the present study, soybean peroxidase (SBP) was covalently immobilized onto two functionalized photocatalytic supports (TiO2 and ZnO) to create novel hybrid biocatalysts (TiO2-SBP and ZnO-SBP). Immobilization caused a slight shift in the pH optima of SBP activity (pH 5.0 to 4.0), whereas the free and TiO2-immobilized SBP showed similar thermal stability profiles. The newly developed hybrid biocatalysts were used for the degradation of 21 emerging pollutants in the presence and absence of 1-hydroxy benzotriazole (HOBT) as a redox mediator. Notably, all the tested pollutants were not equally degraded by the SBP treatment and some of the tested pollutants were either partially degraded or appeared to be recalcitrant to enzymatic degradation. The presence of HOBT enhanced the degradation of the pollutants, while it also inhibited the degradation of some contaminants. Interestingly, TiO2 and ZnO-immobilized SBP displayed better degradation efficiency of a few emerging pollutants than the free enzyme. Furthermore, a combined enzyme-chemical oxidation remediation strategy was employed to degrade two recalcitrant pollutants, which suggest a novel application of these novel hybrid peroxidase-photocatalysts. Lastly, the reusability profile indicated that the TiO2-SBP hybrid biocatalyst retained up to 95% degradation efficiency of a model pollutant (2-mercaptobenzothiazole) after four consecutive degradation cycles.
