“…30,54,55 Thereby, not only chitin− glucan complexes in the form of nanofibrils would be isolated and commercialized, but also lipids (fatty acids) or antioxidants (ergosterol, ergothioneine, tocopherols, vitamin C) with potential uses in food, cosmetic, and pharmaceutical industries. 56,57 Besides, fungi-derived proteins, also known as mycoproteins, can be used as an environmentally and economically sustainable protein source alternative to meat. 58 With no doubt, extracting the products that could not be recovered in our proposed pilot plant would increase the economic feasibility of the process.…”

In times when transitioning from a linear carbonintensive economy into a sustainable circular economy is an urgent need, bio-based nanoparticles such as nanochitins are attracting an increasing interest for value-added products. Fungal chitin nanofibril (ChNF) isolation show a reduced CO 2 footprint over crustacean shell-derived nanochitin, which requires harsh chemical treatments. However, the viability and practical implementation of ChNFs from fungi may depend on the manufacturing costs. Accordingly, here we assess the economic feasibility of a pilot-scale fungi-derived ChNF isolation comprising chitin nanofibrils with covalently bonded β-glucans. Required capital investment, production costs, minimum product selling prices, and payback periods for ChNF isolation are obtained considering a refinery plant treating 3000 kg of fresh mushroom daily and located in Bilbao, north of Spain. The proposed business model offers clear signals of technical, economic, and commercial viability for the pilot industrial plant format, under relatively conservative technical assumptions. In particular, a total capital investment for a pilot-scale biorefinery is estimated at ∼1.10 M€ for ChNFs, where a working capital of ∼380 K€ indicates good short-term financial health of a company. A payback period of 11.3 years with estimated minimum selling price of 212 €•kg −1 for the year 2024 is obtained, which can be lowered to 106 €•kg −1 in a scenario where the chitin extraction yield is doubled. This value remains below the selling value of nanocelluloses from leading manufacturers, making ChNFs from fungi a competitive alternative to develop novel materials addressing the challenges of renewability, environmental sustainability, and functional properties. In particular, the ease of isolation with minimal use of chemicals is a significant economic advantage, although the low yield is a noteworthy drawback for profit after taxes. A sensitivity analysis is conducted by considering five scenarios that can occur upon biorefinery operation. These results highlight the bright future of fungal nanochitin to meet market demands on sustainable materials, especially in value-added applications such as energy storage and biomedicine, where high selling prices are affordable. As applications of fungal nanomaterials are gaining momentum, the techno-economic assessment here shown provides cues for the practical implementation of nanochitin into a sustainable society based on a circular bioeconomy.

“…Bioactive substances. Substances responsible for the diverse positive effects of Laetiporus sulphureus include tocopherols, steroids, triterpenes, beauvericin, organic acids (including laetiporic and ascorbic acids), lectins, pigments, benzofurans, α-glucans, phenolic compounds, polysaccharides and monosaccharides [ 1 , 8 , 30 , 33 , 46 , 84 , 85 , 86 ]. The composition of bioactive substances found in L. sulphureus is similar to the composition of substances found in Pleurotus ostreatus [ 1 ].…”

Sulphur shelf fungus (Laetiporus sulphureus) has so far been largely underestimated as a potential raw material for the food industry. Many studies have demonstrated that the extracts obtained from this mushroom and some of their components have positive effects on human health. They have antioxidant, antibacterial, and anticancer properties and regulate human metabolism and digestive processes. Water extracts also have this effect. In addition, the substances contained in this mushroom have the ability to preserve food by inhibiting the growth of undesirable microorganisms. These properties have led to the situation that in some countries, shelf sulphur fungus is legally recognized as a raw material that meets the requirements of the food and processing industries. This paper is a review of the latest information (mainly for the period 2016–2023) on the chemical composition and the possibility of using L. sulphureus in the food industry and in medicine.

“…Various mushrooms play an important role in the treatment of various diseases, including viral, bacterial, and fungal infections (Chang and Buswell, 1996 ; Khatua et al, 2013 ; Muszyńska et al, 2018 ). The mushroom kingdom contains many compounds with antioxidant properties, which include ergothioneine (a compound occurring in relatively few organisms) and glutathione (an insufficiently explored compound) (Kalaras et al, 2017 ; Quintero-Cabello et al, 2021 ).…”

In addition to their nutritional properties, mushrooms have emerged as a health supplement because of their medicinal potential. Many studies have shown that mushrooms exhibit important biological activities. Here, the antioxidant and antimicrobial activities of Hohenbuehelia myxotricha (Lév.) Singer mycelia cultivated on Sabouraud dextrose broth (SDB) and glucose peptone yeast (GPY) medium were studied. The total antioxidant status (TAS), total oxidant status (TOS), and oxidative stress index (OSI) of ethanolic extracts of mycelia were measured using Rel Assay kits. The antioxidant and oxidant potentials of H. myxotricha mycelial extracts were determined for the first time in the present study. The highest TAS, TOS, and OSI values of H. myxotricha were 5.416 ± 0.150 mmol/l, 1.320 ± 0.156 μmol/l, and 0.024 ± 0.003, respectively. Ethanolic mycelial extracts of H. myxotricha showed antimicrobial activities at concentrations from 25 to 200 μg/ml against all the studied bacteria ( Acinetobacter baumannii, Enterococcus faecalis , Escherichia coli , Staphylococcus aureus , methicillin-resistant S. aureus , and Pseudomonas aeruginosa ) and fungi ( Candida albicans , C. glabrata , and Issatchenkia orientalis ) tested by the agar dilution method. The antifungal activity of the extract was more significant than its antibacterial activity. The antioxidant, oxidant, and antimicrobial potentials of H. myxotricha mycelia varied depending on the culture media used. GPY medium was more suitable for the synthesis of antibiotic compounds against E. coli , while SDB medium was more appropriate for producing metabolites with antioxidant and antifungal properties. Based on the results, ethanolic extract of H. myxotricha mycelia showed a significant pharmacological potential and could be used as a natural antioxidative and antimicrobial source for health benefit.
