“…The white rot (WR) fungi are highly regarded because they are not selective in their degradation process and have the best capability to effectively degrade lignin because of the production of nonspecific ligninolytic extracellular oxidative enzymes . After delignification, the woody substrates are left whitish and fibrous in texture.…”

“…Overall, three primary peroxidase systems have been identified: (a) LIP (lignin peroxidase; syn = ligninase; EC1.11.1.14); (b) MnP; manganese peroxidase, and the VPs (versatile peroxidases; EC 1.11.1.16). 28 Depending on the growth substrates and additives, fungal species, growth conditions and processing, the resultant biocomposite exhibits diverse thermomechanical properties. 30,31 The inhomogeneities resulting from colonization of the substrate by the fungi during growth exacerbate the deviations in the biocomposite's properties.…”

Extrication from the use of fossil-based products has grown more critical in recent years. This disengagement has been driven by deliberate environmental campaigns focusing on climate change and global warming threats and their consequences to humanity. As such, innovative replacements for fossilbased products, primarily by biobased materials, have recently been of considerable interest. Among the biobased materials, mycelium-bound biocomposites enhanced biologically or by nontoxic additives are one of the most creative and ecofriendly solutions because it fulfills the three pillars of sustainable development with positive impacts via circular economy design principles. In this review, the potential of mycelium-bound biocomposites is elucidated by comprehensively covering their state-of-the-art production from design strategies (variety of species, substrates, additives, and growth conditions) to postprocessing techniques and the resulting advanced material features. This review also covers the intriguing and growing areas of applications for mycelium-bound biocomposites, as well as the future outlook for enhanced material circularity and sustainability.

“…The variation in the synthesis of laccases in relation to ligninases may be related to the participation of different peroxidases in the delignification process. According to Zhang et al (2022), laccase plays an initial role in lignin degradation, but delignification only happens more efficiently when this enzyme is combined with other peroxidases. Thus, it is suggested that G. lucidum produced a greater amount of laccases for the initial hydrolysis of the substrate, while the peroxidases act only in a complementary way, not requiring greater production.…”

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.
