“…Daâssi et al (2016) used different fungal laccases for the biotransformation of BPA, and the Coriolopsis gallica laccase showed a more rapid oxidation rate than other fungus laccases. Also, peroxidase from mesquite could remove over 90% phenol from wastewater within min (Garg et al, 2020), whilst peroxidases from horseradish (Rajesh et al, 2017), soybean, and potato (Al-Ansari et al, 2010) need more residence time to reach the same level of removal. When peroxidases were employed for azo dye methyl orange treatment, 0.5 mL crude soybean peroxidase achieved a maximum 81.4% decolorization under the conditions of 1 h incubation at 30 ℃ using 2 mM of hydrogen peroxide and 30 mg/L methyl orange at pH 5.0.…”

“…Animals could act as a lipase source (Meng et al, 2017;Ning et al, 2016), but studies employing animals as enzyme sources for wastewater treatment are scarce. Some plants are important enzyme sources for wastewater treatment, especially for peroxidases (Ely et al, 2017;Garg et al, 2020;Torres et al, 2016). Fungi and bacteria enzymes have been widely employed in wastewater treatment.…”

“…Complete removal of 0.4 mM phenol was achieved by an immobilized laccase after 40 min treatment under the conditions of 35 ℃, pH 4.5 (Fathali et al, 2019). Peroxidases are effective enzymes in the transformation of phenolic compounds since their active sites, namely haem cofactor and redox-activated cysteine/selenocysteine residues, are easy to access (Garg et al, 2020). Research showed that immobilized peroxidases could remove 99.9% 1 mM phenol after 5 h treatment under the conditions of room temperature and pH 7.0 (Wang et al, 2016a).…”

Resistant pollutants like oil, grease, pharmaceuticals, pesticides, and plastics in wastewater are difficult to be degraded by traditional activated sludge methods. These pollutants are prevalent, posing a great threat to aquatic environments and organisms since they are toxic, resistant to natural biodegradation, and create other serious problems. As a high-efficiency biocatalyst, enzymes are proposed for the treatment of these resistant pollutants. This review focused on the roles and applications of enzymes in wastewater treatment. It discusses the influence of enzyme types and their sources, enzymatic processes in resistant pollutants remediation, identification and ecotoxicity assay of enzymatic transformation products, and typically employed enzymatic wastewater treatment systems.Perspectives on the major challenges and feasible future research directions of enzyme-based wastewater treatment are also proposed.

“…One strategy to break this barrier is to look for alternative plant peroxidases—similar to HRP—that can perform the same applications. Thus, many studies focused on applications for alternative peroxidases have been developed: peroxidase from guinea grass leaves as biosensor [ 8 ], turnip peroxidase for analytical and diagnostic kits [ 9 ], radish and turnip peroxidases in organic synthesis [ 10 ], cedar leaf peroxidase for decolorization of dyes [ 11 ], and potato pulp and mesquite ( Prosopis juliflora ) peroxidases for bioremediation of phenolic compounds [ 12 , 13 ].…”

In the present work the radish (Raphanus sativus L.) was used as the low-cost alternative source of peroxidase. The enzyme was immobilized in different supports: coconut fiber (CF), calcium alginate microspheres (CAMs) and silica SBA-15/albumin hybrid (HB). Physical adsorption (PA) and covalent binding (CB) as immobilization techniques were evaluated. Immobilized biocatalysts (IBs) obtained were physicochemical and morphologically characterized by SEM, FTIR and TGA. Also, optimum pH/temperature and operational stability were determined. For all supports, the immobilization by covalent binding provided the higher immobilization efficiencies—immobilization yield (IY%) of 89.99 ± 0.38% and 77.74 ± 0.42% for HB and CF, respectively. For CAMs the activity recovery (AR) was of 11.83 ± 0.68%. All IBs showed optimum pH at 6.0. Regarding optimum temperature of the biocatalysts, HB-CB and CAM-CB maintained the original optimum temperature of the free enzyme (40 °C). HB-CB showed higher operational stability, maintaining around 65% of the initial activity after four consecutive cycles. SEM, FTIR and TGA results suggest the enzyme presence on the IBs. Radish peroxidase immobilized on HB support by covalent binding is promising in future biotechnological applications.

“…The conventional physical and chemical processes for removal of dyes from wastewater, such as coagulation–flocculation, adsorption, ion‐exchange, advanced oxidation processes and others, although currently in industrial/municipal use, have features which could be variously improved upon (cost, breadth of scope, efficiency/effectiveness and/or sludge formation) 3,9 . As an alternative, enzymatic treatment may become a preferred technique for the removal of pollutants owing to its high specificity, applicability to inaccessible pollutants, and ability to act over a wide range of pHs and temperatures under milder reaction conditions, at higher reaction rates 9,10 . Oxidoreductases such as laccases and peroxidases are biocatalysts which convert susceptible pollutants to insoluble oligomers which can then be removed through precipitation and/or filtration 11 .…”

BACKGROUNDThe presence of azo dyes in wastewater from the textile industry is a major environmental concern. The dyes not only make water aesthetically unacceptable, but also have severe toxicological concerns. Research into treatment processes for removal of dyes has focused primarily on decolourization and little attention has been focused on analysis of the degradation products, that could plausibly be more toxic than the parent compound. This study focusses on soybean peroxidase (SBP)‐catalyzed treatment of two azo dyes, Methyl Orange (MO) and CI Direct Yellow 12 (DY12) in water, chosen because they lack phenolic and primary anilino functional groups, which are usually expected to form free radicals under peroxidase catalysis.RESULTSDY12 was found not to be a substrate of SBP, but optimized reaction conditions for 0.50 mmol L–1 MO and 1.0 mmol L–1 p‐anisidine (structurally analogous to 4‐ethoxyaniline, a possible azo‐cleavage product of DY12) achieved ≥95% conversion at exceptionally low minimum effective SBP activities (0.0070 and 0.0018 U mL–1) at pH optima of 4.0 and 5.5 and [hydrogen peroxide]/[substrate] of 2 and 1, respectively.CONCLUSIONSMass spectrometric (MS) analysis for the substrates revealed formation of dimers and trimers for p‐anisidine. For MO, high‐performance liquid chromatography, UV‐visible spectrophotometry and MS provided evidence of azo‐bond cleavage, hetero‐coupling of the dye with the cleavage product and also self‐coupling of the dye through tertiary amine activation. © 2020 Society of Chemical Industry (SCI)
