“…The activity of laccase was rather high, allowing the proposal of laccase participation in atrazine degradation by these fungi. This hypothesis was supported by the study of atrazine degradation in the presence of laccase inducers (guayacol and syringaldezine) under submerged cultivation [77]. The efficiency of herbicide degradation was higher in induced cultures by 78-98% and the highest level of atrazine removal was achieved for Coriolopsis fulvocinerea using guaiacol as an inducer.…”

Understanding herbicide transformation is necessary for pesticide development for their safe and efficient use, as well as for developing pesticide bioremediation strategies for contaminated soil and water. Recent studies persuasively demonstrated the key role of soil white-rot fungi in biotransformation of various anthropogenic environmental contaminants. However, often this common knowledge is not associated with specific metabolic processes of fungi and therefore cannot be transformed into specific recommendations for agricultural practice. The given review offers a systematic collection and analysis of the current knowledge about herbicide transformation by white-rot fungi at the cellular and molecular levels. Special attention is given to the role of oxidative enzymes such as laccases, lignin peroxidases, and manganese peroxidases in the biotransformation processes.

The herbicide atrazine (2-chloro-4-ethylamine-6-isopropylamine-s-triazine) is extensively used for weed control in sugarcane crops. The application of fungi for the biodegradation of xenobiotics has been studied with promising results. Therefore, atrazine degradation mediated by Pleurotus ostreatus INCQS 40310 was evaluated, and the involvement of ligninolytic enzymes along with the degradation process was also investigated. To promote high degradation percentages and rates, a fractional factorial experimental design was first used to determine the most significant medium components for atrazine degradation. This strategy improved atrazine degradation from 39.0% to 71.0% after 15 days, with the formation of different metabolites. Afterward, a 3 2 full factorial design was performed using the variables selected in the first part of this study. The salts FeSO 4 and MnSO 4 showed significant influence in the percentages and the rates of atrazine degradation. The medium optimization resulted in 90.3% and 94.5% of atrazine degradation after 10 days and 15 days, respectively. Although laccase activity was measured during the degradation process, it was not possible to correlate laccase activity with atrazine degradation. The results demonstrated the efficiency of P. ostreatus INCQS 40310 for atrazine degradation, thus demonstrating the potential of this fungus as a bioremediation agent.

“…KoroljovaSkorobogat'ko et al (1998) reported that syringaldazine is a major contributor to laccase production in C. hirsutus, and Rosales et al (2007) stated that 0.11 µmol/L syringaldazine in ground orange peelings culture medium stimulated laccase activity in T. hirsuta, in comparison to control cultures, but 1 mM Cu sulfate + 0.11 µmol/L syringaldazine showed no significant increase in laccase activity. On the other hand, 0.11 µmol/L did not lead to a noticeable increase in laccase activity in C. hirsutus, C. fulvocinerea, or C. maxima (Gorbatova et al, 2006). In another study, 0.21 µmol/L syringaldazine caused a decrease in laccase activity in T. versicolor 1666 strain cultivated under submerged conditions (Shakhova et al, 2011).…”

Introduction Laccases(EC 1.10.3.2, p-diphenol:dioxygen oxidoreductases) are industrially important multicoppercontaining enzymes. Although laccases are produced by some higher plants, insects, bacteria, and fungi, these enzymes are mainly abundant in white rot fungi (Gochev and Krastanov, 2007;Shraddha et al., 2011). These fungi, including Trametes, Pleurotus, Coriolopsis, and other genera, produce laccase enzymes at varying rates (Tapia-Tussell et al., 2011). Trametes is one of the most effective laccase-producing genera (Jang et al., 2002;Rosales et al., 2007). Fungal laccases are generally extracellular and they catalyze the oxidation of a wide range of compounds, such as mono-, di-, and polyphenols, aminophenols, methoxyphenols, aromatic amines, ascorbate, and nonphenolic compounds (Thurston, 1994;Couto et al., 2002;Baldrian, 2006;Patel and Gupte, 2016). The nonnecessity of any extraction process for obtaining these enzymes and their low substrate specificities make laccases suitable for many industrial applications, such as pulp delignification and biobleaching, textile dye decolorization, wastewater treatment, fruit juice processing, and construction of biosensors and biofuel cells (Minussi et al., 2002;Giardina et al., 2010;Durán et al., 2014;Yeşilada et al., 2014). Due to their broad industrial and environmental uses, these enzymes have gained increasing attention. Laccase production can be stimulated by various inductive substances, including metal ions, aromatic or phenolic compounds, alcohol, and detergents (Collins and Dobson, 1997;Birhanli and Yesilada, 2006;Tychanowicz et al., 2006;Bettin et al., 2014). Furthermore, inducer concentration, fermentation types, growth media, and incubation conditions have an important effect on laccase production and they are specific to species and strains (Boran and Yesilada, 2011). Many researchers have investigated the effects of various fermentation processes, cultivation conditions, laccase-producing organisms, and inducers on laccase production (
