“…The edible fruiting body of I. hispidus is a scarce ingredient. I. hispidus possess a good selenium-enriching function [ 62 ], and the antiviral ability of I. hispidus rich in selenium has also been enhanced. The dihydroxy phenylalanine-melanin contained in I. hispidus could effectively remove DPPH radicals and can therefore be used in health food or as a food additive [ 63 ].…”

Inonotus hispidus mushroom is a popular edible and medicinal mushroom with a long history of use. It is well known as a medicinal fungus with various health benefits for its significant anticancer and immunomodulatory activities. Over the last 60 years, secondary metabolites derived from I. hispidus and their biological activities have been discovered and investigated. Structurally, these compounds are mainly polyphenols and triterpenoids, which have anticancer, anti-inflammatory, antioxidant, antimicrobial, and enzyme inhibitor activities. Here, the secondary metabolites derived from I. hispidus and their activities were systematically and comprehensively classified and summarized, and the biosynthetic pathway of stylylpyrones was deduced and analyzed further. This review contributes to our understanding of I. hispidus and will help with research into natural product chemistry, pharmacology, and the biosynthesis of I. hispidus metabolites. According to this review, I. hispidus could be a promising source of bioactive compounds for health promotion and the development of functional foods.

“…Thus far, in some mushroom species, depending upon their growth situation, the selenium form and concentration have shown different abilities to absorb and accumulate selenium [ 36 , 37 ]. In Lentinula edodes mycelia supplemented with selenium, considerable accumulation of this element (from 192.6 to 532.3 mg/100 g) was detected [ 38 ].…”

“…In Lentinula edodes mycelia supplemented with selenium, considerable accumulation of this element (from 192.6 to 532.3 mg/100 g) was detected [ 38 ]. Total Se content in Inonotus hispidus grown with 0.29 mmol/L selenite could reach 532.3 µg/g [ 37 ]. With a Se concentration in the medium between 15.0 and 20.0 mg/L, the biomass of Pleurotus ostreatus , a common edible fungus, reached approximately 9.0 g/L, and the amount of selenium absorbed was about 800 µg/g [ 36 ].…”

Selenium (Se) is an essential nutrient element in human physiological metabolism and immune function. Supplementation of bioavailable Se will confer benefit on human life, especially when intake of this nutrient is inadequate. The edible and medicinal mushroom Antrodia camphorata is a unique fungus endemic to Taiwan, which has shown high therapeutic and nutritive value. This study is the first to demonstrate that A. camphorata can assimilate and transform sodium selenite into organic selenium. With an initial concentration of Se (IV) at 10 mg/L in 100 mL of the medium at 25 °C, the total selenium content in Se-enriched A. camphorata mycelia was 1281.3 ± 79.2 µg/g, in which the organic selenium content accounted for 88.1%. Further analysis demonstrated that selenium-enriched polysaccharide was the main form of Se present in A. camphorata (61.5% of the organic selenium). Four water-soluble Se-polysaccharide fractions were separated from A. camphorata, and ACP II was the major fraction of Se-polysaccharide. The scavenging efficiency of Se-polysaccharides on DPPH and ABTS radicals was determined, proving that selenium enrichment dramatically improved the in vitro antioxidant capacity of A. camphorata polysaccharide. Therefore, the selenium accumulation and transformation ability of A. camphorata provides an opportunity for developing this beneficent fungus into a novel selenium-enriched dietary or medicinal supplement.

“…Despite their use as a dietary supplement in China and other countries, the metabolism and responses of selenium-fortified mushrooms are poorly understood. Selenite’s effect on mushroom fruiting and mycelial development and its adverse impact from toxic quantities have been documented in various mushrooms ( Song et al, 2022 ; Wang et al, 2016 ). For example, addition of 1.0 µg g −1 selenite in the medium resulted in up to 25% increase in mushroom yield of F. velutipes , while 50 µg g −1 selenite treatment significantly inhibit the growth of fruiting body ( Dong, Xiao & Wu, 2021 ).…”

Although Morchella esculenta (L.) Pers. is an edible and nutritious mushroom with significant selenium (Se)-enriched potential, its biological response to selenium stimuli remains unclear. This study explored the effect of selenium on mushroom growth and the global gene expression profiles of M. esculenta. While 5 µg mL−1selenite treatment slightly promoted mycelia growth and mushroom yield, 10 µg mL−1significantly inhibited growth. Based on comparative transcriptome analysis, samples treated with 5 µg mL−1 and 10 µg mL−1 of Se contained 16,061 (452 upregulated and 15,609 downregulated) and 14,155 differentially expressed genes (DEGs; 800 upregulated and 13,355 downregulated), respectively. Moreover, DEGs were mainly enriched in the cell cycle, meiosis, aminoacyl-tRNA biosynthesis, spliceosome, protein processing in endoplasmic reticulum pathway, and mRNA surveillance pathway in both selenium-treated groups. Among these, MFS substrate transporter and aspartate aminotransferase genes potentially involved in Se metabolism and those linked to redox homeostasis were significantly upregulated, while genes involved in isoflavone biosynthesis and flavonoid metabolism were significantly downregulated. Gene expression levels increased alongside selenite treatment concentration, suggesting that high Se concentrations promoted M. esculenta detoxification. These results can be used to thoroughly explain the potential detoxification and Se enrichment processes in M. esculenta and edible fungi.
