“…G. lucidum was reported to contain up to 72 μg Se/g in its fruiting body 34 , while the maximum selenium content in the studied A. cornea was approximately 51 μg Se/g. Moreover, the selenium concentration in Lentinula edodes first ascended and then descended over time 35 , which was consistent with the present study.…”

“…Selenium stimulated the synthesis of various proteins, and it would improve the medical use of A. cornea . Selenium was absorbed and converted into various substances, including selenocysteine, selenomethionine and other compounds 35 . It was demonstrated that the accumulated selenium in G. lucidum protein showed antioxidant activities and selenium protected DNA from being oxidized strongly 54 .…”

Auricularia cornea is a widely cultivated edible fungus with substantial nutritive value. This study aimed to enrich the multifunctional bionutrient element selenium in A. cornea to improve its quality and explore the accumulation of selenium in the fungus using high-throughput RNA-Seq technology. In general, the treatment group with a 100 µg/g supply of selenium outperformed the other treatment groups in terms of high yield, rich crude polysaccharides and a high total selenium concentration. Additional evidences demonstrated the budding and mature phases were two typical growth stages of A. cornea and were important for the accumulation of selenium. Therefore, the budding and mature phase tissues of A. cornea in the treatment group with a 100 µg/g supply of selenium were used for transcriptome analysis and compared to those of a control group that lacked additional selenium. A total of 2.56 × 105 unigenes from A. cornea transcriptome were assembled and annotated to five frequently used databases including NR, GO, KEGG, eggNOG and SwissProt. GO and KEGG pathway analysis revealed that genes involved in metabolic process and translation were up-expressed at the budding stage in response to selenium supplementation, including amino acid metabolism, lipid metabolism, ribosome. In addition, the differential gene expression patterns of A. cornea suggested that the up-expressed genes were more likely to be detected at the budding stage than at the mature stage. These results provide insights into the transcriptional response of A. cornea to selenium accumulation.

“…Zhou et al [126] studied the absorption of inorganic selenium in the fruiting bodies of L. edodes and its transformation into organic derivatives, which was characterized by better digestibility. The authors reported that selenomethionine is the main organic derivative of selenium, which, like selenocysteine, has strong antioxidant properties [119].…”

There are about 3000 species of mushrooms, which have a high amount of substances that are beneficial to human health, such as antioxidants. It is well known that oxidative stress plays an important role in the etiopathogenesis of many diseases, including cancer, cardiovascular disorders, and diseases of the central nervous system. One way to prevent homeostasis disorders that occur as a result of excessive production of pro-oxidative substances is to include the ingredients having antioxidant properties in the diet. Several compounds, such as those with phenolic and indole derivatives as well as carotenoids and some vitamins, exhibit antioxidant activity. These substances are present in many foods, including mushrooms. In addition, they have certain unique compounds that are not found in other sources (e.g., norbadione A). The present work discusses selected ingredients exhibiting antioxidant activity, which are found in various species of mushrooms as wells as describes the content of these compounds in the extracts obtained from mushrooms using artificial digestive juice.

“…SPME is an effective sample preparation technique , and it integrates sampling, extraction, enrichment and sample introduction into one process . Before the appearance of SPME, some traditional methods have been applied , such as liquid‐liquid microextraction , Soxhlet extraction , SPME and so on. Compared with these methods, SPME has higher sensitivity, less time and solvent consumption.…”

Diamond nanoparticles were coated onto stainless steel wires as a extraction material, then it was filled into a poly(ether ether ketone) tube for in‐tube solid‐phase microextraction. Coupled with high‐performance liquid chromatography, the extraction tube was evaluated with different types of analytes including polycyclic aromatic hydrocarbons, estrogens and plasticizers. As the coating, diamond nanoparticles exhibited greater extraction capacity for hydrophobic analytes. Several polycyclic aromatic hydrocarbons were used as model analytes, four main extraction and desorption factors were optimized, including sampling volume, sampling rate, methanol content in sample and desorption time. A sensitive analysis method was established with wide linear range (0.016–20 μg/L), good correlation coefficients (0.9991–0.9997), low limits of detection (0.005–0.020 μg/L), low limits of quantitation (0.016–0.070 μg/L) and high enrichment factors (305‐2396). Relative standard deviations for intra‐ and interday were less than 2.4% (n = 3) and 8.4% (n = 3), respectively. Durability and chemical stability were satisfactory with relative standard deviations less than 7.9% (n = 3). Finally, the method has been successfully applied to the detection of polycyclic aromatic hydrocarbons in real samples.
