“…This species is recognized as edible, being known as chewing-gum fungus or split-gill mushroom (Cooke, 1961;Takemoto et al, 2010). This fungus has a known antioxidant property (Arbaayah & Umi-Kalsom, 2013;Jiamworanunkul, 2019) and a high potential for bioaccumulation of metals such as Fe and Zn in the mycelium, suggesting that this species could be used as a food source in diets which require these micronutrients (Umeo et al, 2020). S. commune occurs in all geographic regions in Brazil, with no record of occurrence only for the state of Tocantins, although distribution models of this species suggest that it should have a wide distribution in these unexplored regions (Braga-Neto, 2013).…”

Food and nutritional potential of two mushrooms native species to the Brazilian savanna (Cerrado)

et al. 2022

Until recently, no native mushroom was considered food in the Cerrado biome, while there are records of the occurrence of about 638 species of fungi so far, many of which have numerous undefined potentials, with the potential for food among them. Our work presents the nutritional aspects of two mushroom species found in an agroforestry system in the Cerrado (Auricularia nigricans and Schizophyllum commune), and a morphological identification key for the edible mushroom species highlighted in this study. The nutritional composition analysis revealed a moisture content of 65 and 41%, proteins of 7 and 10%, ether extract (fat) of 1.3 and 1.5% and fiber of 2 and 2.2% for A. nigricans and S. common, respectively. In this work we highlight the nutritional potential of two species of edible mushrooms, A. nigricans and S. commune. These mushrooms show similar nutritional characteristics to those of commercially produced exotic mushrooms, being rich in proteins and minerals. These data, added to other reports of this nature recently presented, reinforce the importance of knowledge of local biodiversity and native mushrooms as a food source.

“…Iron biofortification and availability from L. crinitus , G. lucidum , Schizophyllum commune , P. ostreatus , P. eryngii , L. edodes, and A. subrufescens grown in two different culture media (malt extract with 0.116 mg L −1 or sugarcane molasses with 91.2 mg L −1 ) were described by Scheid et al [ 56 ]. A comparison of Fe bioaccumulation in mycelial biomass of Letinula edodes , P. eryngii , P. ostreatus, and S. commune grown in malt extract agar with 50 mg L −1 enrichment was made by Umeo et al [ 57 ]. Evaluation of Fe content in P. ostreatus grown on the sugar cane ( Saccharum offiinarum L.) bagasse with the addition of 0.5, 1, 2, 5, or 10 mg kg −1 Fe was performed by Condé et al [ 58 ].…”

Biofortification of Three Cultivated Mushroom Species with Three Iron Salts—Potential for a New Iron-Rich Superfood

et al. 2022

Mushrooms fortified with iron (Fe) can offer a promising alternative to counter the worldwide deficiency problem. However, the factors that may influence the efficiency of fortification have not yet been fully investigated. The aim of this study was to compare the effects of three Fe forms (FeCl3 6H2O, FeSO4 7H2O, or FeHBED) in three concentrations (5, 10, or 50 mM) for three mushroom species (Pleurotus eryngii, P. ostreatus, or Pholiota nameko) on their chemical composition, phenolic compounds, and organic acid production. The most effective metal accumulation of all the investigated species was for the 50 mM addition. FeCl3 6H2O was the most favorable additive for P. eryngii and P. nameko (up to 145 and 185% Fe more than in the control, respectively) and FeHBED for P. ostreatus (up to 108% Fe more than in control). Additionally, P. nameko showed the highest Fe accumulation among studied species (89.2 ± 7.51 mg kg−1 DW). The creation of phenolic acids was generally inhibited by Fe salt supplementation. However, an increasing effect on phenolic acid concentration was observed for P. ostreatus cultivated at 5 mM FeCl3 6H2O and for P. eryngii cultivated at 5 mM FeCl3 6H2O and 5 mM FeSO4 7H2O. In the case of organic acids, a similar situation was observed. For P. ostreatus, FeSO4 7H2O and FeHBED salts increased the formation of the determined organic acids in fruiting bodies. P. eryngii and P. nameko were characterized by a much lower content of organic acids in the systems supplemented with Fe. Based on the obtained results, we recommend starting fortification by preliminarily indicating which form of the element is preferred for the species of interest for supplementation. It also seems that using an additive concentration of 50 mM or higher is most effective.

“…Ganoderma lucidum (Curtis) P. Karst. (Basidiomycotaete: Polyporales) has the ability to bioaccumulate metals of nutritional and pharmacological interest in its mycelial structures (MENIQUETI et al, 2020;SCHEID et al, 2020;UMEO et al, 2020;MATUTE et al, 2011;MENIQUETI et al, 2021). The bioaccumulation of metals in basidiomycetes is a particularly interesting strategy to control the solubility and availability of metals.…”

Lithium is a first-line treatment for bipolar disorder, a disorder that is characterized by alternating manic and depressive episodes. However, because of its narrow therapeutic index, lithium can cause adverse effects. The association of lithium with more complex molecules, such as proteins and polysaccharides, may help control the release of lithium throughout the digestive system, thereby reducing the doses that are used by patients and consequently reducing adverse effects. The present study evaluated the acute oral toxicity of lithium bioaccumulated in mycelial biomass of Ganoderma lucidum, a research step that precedes preclinical efficacy studies. The study followed Organization for Economic Cooperation and Development guideline. Male Wistar rats (n = 6) were acutely treated by gavage with fixed doses (300 and 2000 mg/kg) of lithium bioaccumulated in mycelial biomass of G. lucidum. Changes in clinical signs, body mass, relative organ mass, biochemical parameters, blood count, leukocytes, and histopathological changes were evaluated. A group of animals that were treated with vehicle (n = 6) served as the basal group. No signs of toxicity were observed in any of the investigated parameters. Lithium bioaccumulation in mycelial biomass of G. lucidum did not induce signs of toxicity in rats that were acutely orally treated.
