“…Laccases are another typical phase I enzyme, catalyzing single-electron oxidation of substrates not limited to phenolic substances in the presence of dioxygen [36] They are the favored choices for enzymatic bioremediation of organic contaminants, because of their wide range of substrates, together with their stable and powerful catalytic performance [37]. Figure 3B shows that laccase activity in the shoots and roots of citrus seedling was significantly increased by soil glyphosate, to 2.84 and 2.41 times that of the control, respectively (p < 0.05), indicating that laccase was effectively activated in response to glyphosate stress.…”

A large amount of glyphosate enters the soil at a high frequency, forming “pseudo-persistent” pollutants that, in turn, threaten soil ecological function and crop growth. Earthworm casts (EWCs) are a sound organic alternative to chemical fertilizers to promote crop growth. Dissolved organic matter from EWCs (EWC-DOM) is supposed to be a more mobile and bioavailable fraction. However, the effect of EWC-DOM on the phytotoxicity of glyphosate remains largely unknown. This study examines glyphosate-induced oxidative stress and its impact on antioxidant and detoxification enzymes in citrus plants grown in soils with and/or without EWC-DOM. The results suggest that EWC-DOM could reduce the membrane lipid peroxidation level, thus slowing down the aging of plants in order to maintain stronger resilience, with more active antioxidant enzymes (including SOD, POD, and CAT) and detoxification enzymes (including GST, laccase, CPR, and UGTs) that could effectively remove reactive oxygen species (ROS) caused by glyphosate stress, thereby alleviating the damage of ROS accumulation on plant tissues. Our data indicate that incorporating EWC-DOM should be a sound way to protect citrus plants from the phytotoxicity caused by using glyphosate for orchard weeding. This has major implications for the sustainable and healthy development of citrus production.

“…Enzymatic mycoremediation of hydrocarbons is mainly related to the use of laccases that are already commercially available [76,77]. Although enzymatic degradation of hydrocarbons is more easily carried out in liquid culture compared to the same strains growing in soil, studies of enzymatic mycoremediation in soil microcosms have also shown promising results for hydrocarbon remediation [78,79]. In summary, higher efficiencies in enzymatic mycoremediation are achieved when parameters such as pH, temperature, enzyme loading and Eh are properly controlled [75,80].…”

“…Although fungal laccases show higher Eh than those of bacteria and plants, this potential is still low for oxidation of high molecular weight hydrocarbons [81]. Alternatively, mediating compounds (natural or synthetic) such as 1-hydroxybenzotriazole (HBT), 2,2′-Azino-bis(3ethylbenzthiazoline-6-sulfonic acid) (ABTS), coumaric acid and ferulic acid can be added to the reaction medium, which are initially oxidized (by laccase) forming reactive oxygen species (ROS) that increase the Eh for oxidation of higher molecular weight hydrocarbons [79,82]. The oxidation of ABTS by laccases may be influenced by mediator concentration and water availability [75,80]; since greater degradation of benzo[a]pyrene was speculated to occur in aqueous solutions than in soil microcosms, both containing ABTS [80].…”

The practical use of enzymatic mediators, however, may be unfeasible due to high costs and possible increase in toxicity [78,79].…”

Petroleum hydrocarbons and toxic metals are sources of environmental contamination and are harmful to all ecosystems. Fungi have metabolic and morphological plasticity that turn them into potential prototypes for technological development in biological remediation of these contaminants due to their ability to interact with a specific contaminant and/or produced metabolites. Although fungal bioinoculants producing enzymes, biosurfactants, polymers, pigments and organic acids have potential to be protagonists in mycoremediation of hydrocarbons and toxic metals, they can still be only adjuvants together with bacteria, microalgae, plants or animals in such processes. However, the sudden accelerated development of emerging technologies related to the use of potential fungal bioproducts such as bioinoculants, enzymes and biosurfactants in the remediation of these contaminants, has boosted fungal bioprocesses to achieve higher performance and possible real applications. In this review, we explore scientific and technological advances in bioprocesses related to the production and/or application of these potential fungal bioproducts when used in remediation of hydrocarbons and toxic metals from an integral perspective of biotechnological process development. In turn, it sheds light to overcome existing technological limitations or enable new experimental designs in the remediation of these and other emerging contaminants.

“…For example, ABTS has improved the removal of both phenol and non-phenol synthetic dyes (bromophenol blue, xylene cyanol, Coommassie ® Brilliant Blue R-250) by an immobilized Lac [ 14 ]. ABTS or a nature-derived mediator, ferulic acid, have been useful for the remediation of soil contaminated with polyaromatic hydrocarbons [ 15 ]. ABTS was used together with carbon nanotubes to mediate the oxidation of anthracene to the corresponding quinone.…”

Laccases (Lac) and tyrosinases (TYR) are mild oxidants with a great potential in research and industry. In this work, we review recent advances in their use in organic synthesis. We summarize recent examples of Lac-catalyzed oxidation, homocoupling and heterocoupling, and TYR-catalyzed ortho-hydroxylation of phenols. We highlight the combination of Lac and TYR with other enzymes or chemical catalysts. We also point out the biological and pharmaceutical potential of the products, such as dimers of piceid, lignols, isorhamnetin, rutin, caffeic acid, 4-hydroxychalcones, thiols, hybrid antibiotics, benzimidazoles, benzothiazoles, pyrimidine derivatives, hydroxytyrosols, alkylcatechols, halocatechols, or dihydrocaffeoyl esters, etc. These products include radical scavengers; antibacterial, antiviral, and antitumor compounds; and building blocks for bioactive compounds and drugs. We summarize the available enzyme sources and discuss the scalability of their use in organic synthesis. In conclusion, we assume that the intensive use of laccases and tyrosinases in organic synthesis will yield new bioactive compounds and, in the long-term, reduce the environmental impact of industrial organic chemistry.
