“…Esto se debe a que el aumento de PPL incrementó la concentración inicial de enzima peroxidasa. Kurnik et al (2018) reportaron ascensos en los valores de remoción de 2,4-dichlorophenol cuando aumentaron la concentración inicial de pulpa de papa. En todos los ensayos: ABTS0 = 0,47 mM, P0 = 0,41 mM.…”

“…En los Andes Sudamericanos, este cultivo juega un rol fundamental en la seguridad alimentaria y en la economía rural y campesina. Por lo anterior y considerando que la papa es una fuente de enzimas peroxidasas (Kurnik et al, 2018) y que, además, tiene el potencial de adsorber colorantes industriales (Stavrinou et al, 2018), el presente trabajo propone investigar el uso de pulpa de papa para la remoción de orange II como un modelo de contaminante industrial.…”

En el presente estudio se acondicionó un biomaterial a base de pulpa de papa liofilizada (PPL) para la remoción de un colorante industrial, Orange II (S), con peróxido de hidrógeno (P). El uso de enzimas es actualmente una de las tecnologías más promisorias para la eliminación de contaminantes industriales recalcitrantes. Se caracteriza la actividad peroxidasa de PPL mediante la oxidación de ácido 2,2'-azino-bis-(3-etillbenzotiazolin-6-sulfónico) (ABTS) y su capacidad para remover S. Los resultados indicaron que PPL es una potencial fuente de enzima peroxidasa y que además tiene la capacidad para eliminar el Orange II mediante oxidación enzimática y bioadsorción. Esto aporta la catálisis enzimática, un 65 % de la remoción total del colorante. Se concluye que la decoloración de S con P en presencia de PPL es conveniente realizarla a pH 9 y un valor inicial de P0/S0 = 10 mol/mol.

“…It was reported that about 98% of was successfully removed by soybean peroxidase within 30 min in comparison, with only 36.5% degrading efficiency achieved by using horseradish peroxidase with the same treatment period [114]. The degradation efficiency of the peroxidases obtained from potato in eliminating 2,4-dichlorophenol from wastewater was also evaluated, and it was revealed that about 98% of the pollutant was removed from the sample with an initial phenolic concentration of 1-3 mM [115]. This study highlighted the potential application of the peroxidases extracted from food wastes in the remediation of the phenols from wastewater.…”

Phenol and its derivatives are hazardous, teratogenic and mutagenic, and have gained significant attention in recent years due to their high toxicity even at low concentrations. Phenolic compounds appear in petroleum refinery wastewater from several sources, such as the neutralized spent caustic waste streams, the tank water drain, the desalter effluent and the production unit. Therefore, effective treatments of such wastewaters are crucial. Conventional techniques used to treat these wastewaters pose several drawbacks, such as incomplete or low efficient removal of phenols. Recently, biocatalysts have attracted much attention for the sustainable and effective removal of toxic chemicals like phenols from wastewaters. The advantages of biocatalytic processes over the conventional treatment methods are their ability to operate over a wide range of operating conditions, low consumption of oxidants, simpler process control, and no delays or shock loading effects associated with the start-up/shutdown of the plant. Among different biocatalysts, oxidoreductases (i.e., tyrosinase, laccase and horseradish peroxidase) are known as green catalysts with massive potentialities to sustainably tackle phenolic contaminants of high concerns. Such enzymes mainly catalyze the o-hydroxylation of a broad spectrum of environmentally related contaminants into their corresponding o-diphenols. This review covers the latest advancement regarding the exploitation of these enzymes for sustainable oxidation of phenolic compounds in wastewater, and suggests a way forward.

“…Horseradish peroxidase (HRP) was reported to effectively remove sulfamazine (SMR) in a relatively short time, exhibiting a removal rate of 79.7% [37]. Potato pulp peroxidase reportedly removed 98% of 2,4-dichlorophenol (2,4-DCP) under the most favorable reaction conditions [38]. The manganese peroxidase from Trametes versicolor exhibited complete removal of NOR, CIP, and OFL within 14 days [39].…”

In the present work, a comprehensive screening and evaluation system was established to improve the plant–microbial synergistic degradation effects of QNs. The study included the construction of a 3D-QSAR model, the molecular modification, environmental friendliness and functional evaluation of drugs, degradation pathway simulation, and human health risk assessment. Molecular dynamics was applied to quantify the binding capacity of QNs toward the plant degradation enzyme (peroxidase) and microbial degradation enzymes (manganese peroxidase, lignin peroxidase, and laccase). The fuzzy comprehensive evaluation method was used in combination with the weighted average method for normalization and assigning equal weights to the plant and microbial degradation effect values of the QNs. Considering the synergistic degradation effect value as the dependent variable and the molecular information of the QNs as the independent variable, a 3D-QSAR model was constructed for the plant–microbial synergistic degradation effect of QNs. The constructed model was then employed to conduct the molecular modification, environmental friendliness and functional evaluation, degradation pathway simulation, and human health risk assessment of transformation products using pharmacokinetics and toxicokinetics. The results revealed that the synergistic degradation effect 3D-QSAR (CoMSIA) model exhibited good internal and external prediction ability, fitting ability, stability, and no overfitting phenomenon. Norfloxacin (NOR) was used as the target molecule in the molecular modification. A total of 35 NOR derivatives with enhanced plant–microbial synergistic degradation effect (1.32–21.51%) were designed by introducing small-volume, strongly electronegative, and hydrophobic hydrogen bond receptor groups into the active group of the norfloxacin structure. The environment-friendliness and the functionality of NOR were evaluated prior to and after the modification, which revealed seven environment-friendly FQs derivatives exhibiting moderate improvement in stability and bactericidal efficacy. The simulation of the NOR plant and microbial degradation pathways prior to and after the modification and the calculation of the reaction energy barrier revealed Pathway A (D-17 to D-17-2) and Pathway B (D-17 to D-17-4) as the most prone degradation pathways in plants and Pathway A (D-17 to D-17-1) and Pathway B (D-17 to D-17-4) as the most prone degradation pathways in microorganisms. This demonstrated that the degradation of the modified NOR derivatives was significantly enhanced, with the hydroxylation and piperazine ring substitution reaction playing an important role in the degradation process. Finally, the parameters, including hepatotoxicity, mutagenicity, and rodent carcinogenicity, among others, predicted using the pharmacokinetics and toxicokinetics analyses revealed a significant reduction in the human health risk associated with the modified NOR, along with a considerable reduction in the toxicity of its transformation products, implying that the human health risk associated with the transformation products was reduced remarkably. The present study provides a theoretical basis for novel ideas and evaluation programs for improving the plant–microbial synergistic degradation of the QNs antibiotics for source control and drug design, thereby reducing the residues of these antibiotics and the associated hazard in the complex plant–soil environment, ultimately decreasing the potential risks to human health.
