“…The biological efficiency (BE) and the primordial formation of the substrates are shown in Table 2. P. djamor reached its highest BE in T2, which is a mixture of agave bagasse substrate with barley straw (3:1) and coincides with what has been pointed out by some authors: yield and BE increase when using mixtures of substrates in comparison with pure substrates [8,10,13,14]. On the other hand, the lowest biological efficiency is observed in T1, which is a pure substrate of Agave bagasse; in addition, there is a statistically significant difference between treatments as shown in Table 2.…”

“…Finally, all the mentioned results show that the substrate on which P. djamor mushrooms are grown influences their nutritional and nutraceutical value, as shown by [ 14 , 38 , 54 ]. Nevertheless, this study does not show the nutritional or antioxidant content of the substrates used, the results found in the 5 treatments are different, as acknowledged by the mentioned authors.…”

Identification of Secondary Metabolites of Interest in Pleurotus djamor Using Agave tequilana Bagasse

et al. 2023

Agro-industrial residues represent more than 60% of organic wastes worldwide, which could be used to generate other by-products or to be incorporated into other production chains. For example, bagasse is a waste from the tequila industry in Mexico that could be implemented for mushroom cultivation. Additionally, the substrate influences the growth, development, and production of secondary metabolites of fungi. This work presents a comparative experiment that studies the metabolite production in Pleurotus djamor mushrooms on agave bagasse and barley straw (traditional substrate). The biological efficiency (BE), yield, phenolics and flavonoids, antioxidant capacity, tannins, and the identification of low molecular weight metabolites were evaluated. Five treatments were proposed according to the following mixtures of agave bagasse: barley straw: T1 (1:0), T2 (3:1), T3 (1:1), T4 (1:3), and T5 (0:1). T2 had the highest yield (13.39 ± 3.23%), BE (56.7 ± 13.71%), and flavonoids (44.25 mg rutin equivalent (RE)/g); T3 obtained the highest phenol content (230.27 mg GAE/g); and T1 the highest tannins content (0.23 mg (+) catechin equivalent (CE)/g). Finally, T1 and T5 are the ones that present the greatest number of primary metabolites, including hydroxycitric acid, 2-deoxy-D-galactose, D-mannose, paromomycin, palmitic acid, pyrrole, mannitol, and DL arabinose, while in T2, T3, and T4 only two chemical compounds were found present (palmitic acid and pyrrole in T2, silicic acid and pyrrole in T3 and 2-deoxy-D-galactose and quinoline in T4). The cultivation substrate influences the concentration of bioactive molecules in the fruiting bodies of P. djamor. Additionally, P. djamor’s degradation of agave bagasse residue generates a potential application for agro-industrial residue management at a low cost.

“…In the case of Pleurotus djamor, fruit bodies grow very fast and remain edible for just about two or three days, making them difficult to collect in the right state of softness and texture for consumption. This species requires much local attention given its good quality nutrients and other molecules related to improving health such as antioxidants, tannins, flavonoids, terpenoids (Nayak et al 2021) with the advantage of having already a technology of cultivation developed in other parts of the world, that includes the use of crop wastes such as maize, coffee, rice and palm (Hutabarat et al 2022; Vega et al 2022), that also grow in these communities.…”

Ecuador is a multicultural and megadiverse country where nearly 50 species of wild edible macrofungi (WEM), used by 12 indigenous peoples, have been reported. The Kichwa use 29 species of mushrooms, but aspects of their ecology are unknown. The aim of this study was to study the richness, use, substrates and fruiting seasons of WEM consumed by two peri-urban Kichwa communities settled in the piedmont between the Andes and the Amazon. Between May 2019 to April 2020, we conducted 56 interviews with adults and 12 walks in the chagras and forests. People recognized 26 fungal names related to 12 species of mushrooms, 11 basidiomycetes and one ascomycete. Three species were the most culturally important : Favolus tenuiculus, Bresodolia paradoxa and Lentinus concavus, defined by their abundance, economic importance and taste. Six mushroom species were newly reported for the Kichwa group and four species added to the list of species in the country. All the fungi were lignicolous; they were found on the trunks of 16 species of plants in the chagras. The plant-trees: P. discolor, Inga edulis and C. alliodora were the most common substrates. These species are abundant in the chagras and frequently used for their wood. Ecological and traditional knowledge related to WEM is important to enhance management practices in situ and ex situ.

“…The current ndings show a much higher yield and BE compared to the result of (Harith et al 2014), whose mushroom yield was 27.7 g and a BE of 3.2% when T. versicolor was grown on oak sawdust. Moreover, these do not only depend on the nutritional balance obtained from substrates, since there are other environmental factors that can determine the fungal capacity to achieve successful bio-conversion of the substrate, such as its aeration, relative humidity during various growth stages, and substrate water retention (Vega et al 2022).…”

Despite being one of the most studied white-rot fungi, nothing has been done to discover and domesticate Ethiopia's high-yielding wild Trametes versicolor. Thus, this study was initiated to evaluate the growth performance of T. versicolor on growth media. Accordingly, ten substrates (S1–S10) were formulated by a combination of agroindustrial by-products that mainly constituted sugarcane wastes and animal manures. The effect of substrates on yields, biological efficiencies, and nutritional compositions was examined. The mushroom developed a white, cottony mass on the growth media. T. versicolor cultivated on the S5 combination of 80% sugarcane bagasse, 12% horse manure, and 8% poultry manure had the highest yield (158.33 g/500 g bag) and biological efficiency (31.5%), which had an optimum 31:1 C:N. It has shown good mycelial growth, short colonization, and short pinhead formation time compared to other substrates. Low biological efficiency and yields of 11.50% and 57.67% were obtained from S7, which was not supplemented with nitrogen sources. The content of crude protein, fiber, low fat, and carbohydrates were in the range of 7.46–14.65%, 12.89–18.38%, 0.42–0.53%, and 48.75–66.75%, respectively. The highest nutritional values were obtained from S5, except for carbohydrates from sugarcane bagasse mixed with cotton seed hull (S8). Thus, S5 was found to be a suitable growth medium for domesticating wild T. versicolor mushrooms, particularly in regions where poultry, horse manures, and sugarcane bagasse are abundantly available. Hence, S5 is an optimum substrate for T. versicolor cultivation to improve productivity and nutritional quality at lower costs.
