“…For Levafix Brilliant Red E4BA, a crude enzymatic preparation containing laccase of Pleurotus sajor caju (30 U L -1 ) was not able to degrade it at any of the evaluated pH values (2.4 to 5.0) [21]. According to Schallemberger and coauthors [22], the zero charge point of SMS is 5.5, indicating that below 5.5 the SMS has positive charge and above 5.5 has negative charge, resulting in better adsorption for cationic species. The main difference in dye removal was observed changing pH 4 to 6, as presented in Figure 2.…”

This study evaluated the removal mechanisms of azo dyes from synthetic textile wastewater using spent mushroom substrate (SMS). The simultaneous adsorption and enzymatic degradation were analyzed. The effect of pH, SMS concentration and temperature were studied. The maximum enzymatic degradation (16.36%) was obtained at pH 4 and 65 g SMS L -1 , whereas the maximum adsorption (62.86%) at pH 8 and 155 g SMS L -1 , both at 25°C. The simultaneous enzymatic degradation and adsorption led to the removal of 75.67%. with increased color change. The kinetic study showed that dye adsorption was obtained in the first 30 minutes while the enzymatic degradation increased slowly over the time. The treatment with SMS resulted in the removal of 28.75% of the true color and no increase of effluent toxicity.

“…The enzymatic systems present in SMS of various fungal species make possible their application for different purposes. For example, P. ostreatus SMS can be applied for decolorizing textile effluents because it contains oxidoreductases that degrade the dye molecules [ 164 ]. Similarly, the laccase and manganese peroxidase activities of P. pulmonarius SMS allow its direct application to remove polycyclic aromatic hydrocarbons from contaminated soil samples [ 165 ].…”

“…dialysis, ultra-filtration, anion-exchange chromatography, or gel filtration, of the extracted enzymes are not always described in detail. Production of crude enzyme extracts and their application in areas where expensive purification can be avoided is often reported [ 164 , 181 , 182 ]. Some studies provide the exact identification of the extracted enzymes, including the complete EC classification number, while other provide trivial names or a more general classification without stating details.…”

Spent mushroom substrate (SMS) is the residual biomass generated after harvesting the fruitbodies of edible/medicinal fungi. Disposal of SMS, the main by-product of the mushroom cultivation process, often leads to serious environmental problems and is financially demanding. Efficient recycling and valorization of SMS are crucial for the sustainable development of the mushroom industry in the frame of the circular economy principles. The physical properties and chemical composition of SMS are a solid fundament for developing several applications, and recent literature shows an increasing research interest in exploiting that inherent potential. This review provides a thorough outlook on SMS exploitation possibilities and discusses critically recent findings related to specific applications in plant and mushroom cultivation, animal husbandry, and recovery of enzymes and bioactive compounds.

“…Peroxidases or peroxide reductases (EC 1.11.1.x) are a group of enzymes that require H2O2 or other peroxides to act as an acceptor or donor of hydrogen atoms, and oxidize a wide range of polyphenols (Jaouadi et al, 2019;Agunbiade et al, 2021). In recent years, the enzymes have been applied in numerous industrial processes, such as wastewater treatment, catalysis of chemical transformations (Yadav & Yadav, 2015), dye bleaching (Schallemberger et al, 2021;Sosa-Martínez et al, 2020), bioethanol production (Devi et al, 2022), and prevention of undesirable phenolic oxidation of food components (Narnoliya et al, 2019).…”

White rot fungi have one of the most efficient oxidative lignin degradation systems, and present an enzymatic complex that is responsible for digesting lignocellulosic matter. The aim of this study was to evaluate the production of laccase and total peroxidases by Ganoderma lucidum via solid-state fermentation using açaí seeds and marupá (Simarouba amara) sawdust unsupplemented and supplemented with wheat, corn and rice bran. G. lucidum was inoculated in substrates prepared with the residues and incubated at 25 ºC. Enzymatic extractions were performed on the culture substrates every 2 days for 30 days. The enzymatic activities were determined using ABTS (2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt), with the addition of the enzymatic cofactor H2O2 for total peroxidases. The laccase activity was higher in the supplemented residues, with emphasis on the açaí-based substrate on the 16th day of cultivation, while in marupá the maximum activity was on the 6th day. In the unsupplemented açaí residue, the maximum peak of activity was on the 8th day and, in marupá, no fungal growth was observed. As for total peroxidases, G. lucidum cultivated in the supplemented açaí substrates showed activity peaks on the 8th, 12th, 16th and 28th day, and on 6th and 12th day under unsupplemented conditions. While, in the marupá, total peroxidase activity was observed only on the 6th day of cultivation. Thus, G. lucidum showed potential for producing laccases and total peroxidases, with the substrate supplementation inducing the synthesis of these enzymes.
