“…65,66 In the study conducted by Chatterjee and Abraham, 67 crude LiP produced from the fungal isolation of Trichoderma citrinoviride AJAC3 from sewage showed high efficiency (99.6%) degradation of 17 ⊎-estradiol (E2). In another study, authors reported that LiP could effectively remove E2, and such reactions are significantly enhanced in the presence of VA. 68,69 It was also possible to observe the catalytic efficiency of LiP produced by Ganoderma applanatum and Laetiporus sulphureus in the removal of celecoxib, diclofenac, and ibuprofen. Results indicated a reduction of approximately 98%, 96%, and 95%, respectively, by combining the fungal intercropping.…”

With the growing population and rapid industrial development of the world, various pollutantsexplicitly known as emerging pollutants (EPs) and including micro and nanoplastics, pharmaceuticals, hazardous dyes, steroid estrogen, and organic pollutantscontinue to enter into the environment and water sources. These EPs cause a variety of side effects and diseases, such as cancer, neurotoxic and mutagenic effects, stomach cramps, intestinal disorders, loss of peripheral vision, deteriorated movement coordination, and weakened muscles, even in low concentrations. The presence of EPs in the environment/water sources affects humans and animals and disturbs ecological integrity. Therefore, removing these EPs from the environment with a smart, greener, and environmentally competent technology has become a meaningful goal. Most of the EPs are stable in the media, and their removal is a considerable scientific challenge. Different treatment methods, like adsorption and degradation processes, have been used to eliminate these pollutants. Enzyme-mediated approaches hold immense prospects in environmental cleanup and have been keenly explored recently. Many efforts have been made to apply biocatalytic-based materials, like laccases and peroxidases, as unique tools alongside a powerful oxidation approach for the degradation and treatment of EPs. These enzymes' unique properties in terms of excellent selectivity and exclusive catalytic features make them robust candidates for biocatalytic treatment. This work spotlights the biocatalytic properties and application of oxidoreductases to remove EPs. The challenges, conclusive remarks, and standpoints for robust biocatalysts are also given.

“…In addition to lignin depolymerization, LiP is active in delignification due to its efficiency in removing lignin from lignocellulosic biomass 79,80 . In general, what differentiates LiP from classical peroxidases is the fact that LiP oxidizes aromatic rings that are activated by electron‐donating substrates, whereas classical peroxidases act only on already activated aromatic substrates 81 …”

The applications of enzymes have reached an increasing prominence in the scenario of biocatalysis, stimulated mainly by advances in biotechnological processes to obtain products of high added value. The justification for this is the relevant growth of industrial activities that promote the production of various organic contaminants. Thus, enzymes offer the potential to improve industrial processes used in the food, pharmaceutical, textile, pulp and paper sectors. Specifically, the lignin‐modifying enzymes (LMEs) produced by white rot fungi are versatile biocatalysts. Due to their high specificity, a higher yield of biotechnological processes can be achieved, allowing one to obtain biodegradable products and reducing the amount of waste generated. Thus, evaluating the ligninolytic capacity of these enzymes can be a practical approach from the point of view of bioremediation to develop sustainable procedures in the treatment of recalcitrant organic compounds. In this context, this review provides an overview of the use of LMEs in industrial applicability, as well as their potential in contaminant degradation. Besides, this approach emerges to elucidate further the mechanisms of action and properties of LMEs, which have been gaining relevance in the context of lignocellulosic biorefinery. © 2021 Society of Chemical Industry (SCI).

“…Interestingly, LiP has a higher redox potential (E 0 ≈ 1.2 V versus Standard hydrogen electrode, SHE) than other oxidases and therefore can oxidize both phenolic and non-phenolic compounds in the absence of mediators [17,104]. This advantage of LiPs displayed the broad substrate specificities for a variety of applications to degrade recalcitrant petroleum-based chemicals [105][106][107].…”

Mushroom ligninolytic enzymes are attractive biocatalysts that can degrade lignin through oxido-reduction. Laccase, lignin peroxidase, manganese peroxidase, and versatile peroxidase are the main enzymes that depolymerize highly complex lignin structures containing aromatic or aliphatic moieties and oxidize the subunits of monolignol associated with oxidizing agents. Among these enzymes, mushroom laccases are secreted glycoproteins, belonging to a polyphenol oxidase family, which have a powerful oxidizing capability that catalyzes the modification of lignin using synthetic or natural mediators by radical mechanisms via lignin bond cleavage. The high redox potential laccase within mediators can catalyze the oxidation of a wide range of substrates and the polymerization of lignin derivatives for value-added chemicals and materials. The chemoenzymatic process using mushroom laccases has been applied effectively for lignin utilization and the degradation of recalcitrant chemicals as an eco-friendly technology. Laccase-mediated grafting has also been employed to modify lignin and other polymers to obtain novel functional groups able to conjugate small and macro-biomolecules. In this review, the biochemical features of mushroom ligninolytic enzymes and their potential applications in catalytic reactions involving lignin and its derivatives to obtain value-added chemicals and novel materials in lignin valorization are discussed.
