Type 1 diabetes mellitus(T1DM) lacks insulin secretion due to autoimmune deficiency of pancreaticβ-cells.Protecting pancreatic islets and enhancing insulin secretion has been therapeutic approaches.Mannogalactoglucan is the main type of polysaccharide from natural mushroom,which has potential medicinal prospects.Nevertheless,the antidiabetic property of mannogalactoglucan in T1DM has not been fully elucidated.In this study,we obtained the neutral fraction of alkali-soluble Armillaria mellea polysaccharide(AAMP-N) with the structure of mannogalactoglucan from the fruiting body of A.mellea and investigated the potential therapeutic value of AAMP-N in T1DM.We demonstrated that AAMP-N lowered blood glucose and improved diabetes symptoms in T1DM mice.AAMP-N activated unfolded protein response(UPR) signaling pathway to maintain ER protein folding homeostasis and promote insulin secretion in vivo.Besides that,AAMP-N promoted insulin synthesis via upregulating the expression of transcription factors,increased Ca^(2+) signals to stimulate intracellular insulin secretory vesicle transport via activating calcium/calmodulin-dependent kinase Ⅱ(CamkⅡ) and cAMP/PKA signals,and enhanced insulin secretory vesicle fusion with the plasma membrane via vesicle-associated membrane protein 2(VAMP2).Collectively,these studies demonstrated that the therapeutic potential of AAMP-N on pancreatic islets function,indicating that mannogalactoglucan could be natural nutraceutical used for the treatment of T1DM. 展开更多

The molecular mechanisms of energy status related to the umami taste of postharvest shiitake mushrooms during spore release remain poorly understood.In this study,the variations of energy status and umami taste of mushrooms were measured at 25℃.At 24 h storage,slight spore prints of mushrooms were first pictured,respiration peaked.Significant ATP decrease and ADP increase were also observed as the initiation of postharvest senescence(P<0.05).Meanwhile,the activities of phosphohexose isomerase,succinate dehydrogenase,glucose-6-phosphate dehydrogenase and cytochrome c oxidase and the contents of umami nucleotides and amino acids were maintained at higher levels in mushrooms with spore release.Notably,the equivalent umami concentration(EUC)was strongly correlated with energy levels(R=0.80).Fifteen related gene expression levels in the energy metabolism pathway were downregulated.LecpdP1 and LeAK were significantly expressed in the conversion of ATP into AMP and played key roles in connecting the energy state and umami level.These results provided valuable insights on the umami taste associated with energy metabolism mechanism during postharvest mushroom spore release. 展开更多

Mushrooms have been utilized by humans for thousands of years due to their medicinal and nutritional properties.They are a crucial natural source of bioactive secondary metabolites,and recent advancements have led to the isolation of several alkynyl-containing compounds with potential medicinal uses.Despite their relatively low abundance,naturally occurring alkynyl compounds have attracted considerable attention due to their high reactivity.Bioactivity studies have shown that alkynyl compounds exhibit significant biological and pharmacological activities,including antitumor,antibacterial,antifungal,insecticidal,phototoxic,HIV-inhibitory,and immunosuppressive properties.This review systematically compiles 213 alkynyl-containing bioactive compounds isolated from mushrooms since 1947 and summarizes their diverse biological activities,focusing mainly on cytotoxicity and anticancer effects.This review serves as a detailed and comprehensive reference for the chemical structures and bioactivity of alkynyl-containing secondary metabolites from mushrooms.Moreover,it provides theoretical support for the development of chemical constituents containing alkynyl compounds in mushrooms based on academic research and theory. 展开更多

The isolated secondary metabolites from 39 edible mushrooms are reported,among which 107 compounds were active,61 demonstrated antitubercular activities with IC_(50) range of 0.2-50μg/mL and 46 manifested antimalarial effects with IC_(50) range of 0.061-36μg/mL.While more than 2000 strains of edible mushrooms are identified,this review shows the paucity of research in these rich organisms featuring a vital culinary ingredient worldwide.A thorough search was conducted on basidiomycetes to discuss the chemistry and biology of the isolated compounds,structure activity relationships(SAR)as well as the cytotoxicity profiles of,primarily,the active anti-plasmodial and antitubercular molecules.With a safe cellular profile,lanostane triterpenoids were found to be the only molecules with combined activities against both diseases.SAR correlations reviewed here indicated the significance of 3β-and 7α-hydroxylation in the anti-tuberculosis activity and the terminal unsaturated moiety between C-4 and C-28 in the antimalarial activity in the same terpene skeleton.This review will attract the attention of medicinal chemists,and food scientists to optimize and rationalize the use of mushrooms both as unexploited sources of novel molecules and as nutraceuticals to treat two of the deadliest infectious diseases,malaria,and tuberculosis. 展开更多

The heavy metal bioaccumulation levels of 13 species of mushrooms were studied. 13 different species of wild mushrooms growing in China were analyzed for Cu, Zn, Pb, Cd, and As. Contents of Cu, Zn, Cd and Pb in mushroom and Cu, Zn in Soil were tested by atomic absorption spectrometer (AAS), and As in samples by atomic fluorescent light (AFL). Contents of Cd and Pb in soil were analyzed by graphite furnace AAS. The results showed that contents of Cu, Pb, Cd, and As in Termitomyces microcarpus were the highest in the tested mushroom samples, which were 135.00, 13.28, 65.30, and 1.60 mg·kg^-1 (dry biomass) respectively, and the corresponding bioconcentration factor (BCF) for Cu and Cd was 57 and 1 674 separately, which was the highest data in 13 mushroom species. The capability ofBoletus griseus for Cd accumulation was very strong with BCF of 300. when people consume the wild edible mushrooms, contents of Cd and Pb should be greatly considered. 展开更多

The application of molecular tools for the identification of strains,populations and species has become a common practice in a variety of applied and basic investigations in many parts of the world.However,standardization of such applications varies widely among organisms and scientific fields.In this mini-review,the author provides a brief introduction to one of the most prominent effort for species identification-the international barcode of life(iBOL) project,discusses the features of fungal diversity including the proposed fungal barcode DNA fragment-the intergenic spacer regions(ITS) of the nuclear ribosomal RNA gene clusters,and illustrates the potential promises and problems of using ITS for barcoding and for analyzing the phylogeographic pattern of the wild gourmet mushroom Tricholoma matsutake species complex.The analyses show that identification to species level is often insufficient for practical applications and that sequences from multiple genes in combination with critical morphological and physiological evaluations are needed to identify strains,populations and species. 展开更多

The Phellinus mushrooms have been known for its immunomodulatory, hypolipidemic, and anticancer activities. In the current work, the chemical constituents of two Phellinus mushrooms, Phellinus pini 141016# and Phellinus sp. 150802#, which were collected in Foshan city, Guangdong province, were investigated preliminarily by pre-test tube method and by comparison with the known natural compounds from Phellinus pini, and their antioxidant activities were evaluated by the biochemical assay of hydroxyl and 2,2-diphenyl-1-pricylhydrazyl (DPPH) radicals scavenging activity in vitro. The results show that both the two Phellinus mushrooms contain phenolics, alkaloids, lactones, steroids and terpenoids, and have potent antioxidant activities. The IC50 values of DPPH radicals and hydroxyl radicals for Phellinus pini 141016# were 74.37 μg/mL and 59.69 μg/mL, respectively, and the IC50 values of DPPH radicals and hydroxyl radicals for Phellinus sp. 150802# were 98.95 μg/mL and 165.47 μg/mL, respectively. They are comparable to the antioxidant activity of the standard antioxidant ascorbic acid. 展开更多

The mushrooms are highly regarded as one of the most nutritious foods across the globe but also recognized bio-accumulators of heavy metals. The nature and level of industrial activities are continually changing and affecting the environment adversely. The mushrooms are not an exception and may inevitably have heavy metal contaminations. In this vein, this study aimed to determine heavy metal (Cu, Ni, Co, Zn, Pb, and Cd) uptake levels in wild edible mushrooms from the sites with different economic activities. The wild mushrooms considered for this study included Tente (Amanita Zambiana), Ichikolowa (Termitomyces Titaniscus), and Kabansa (Lactarius Tataniscus). The analysis of heavy metal concentration was carried out using atomic absorption spectrometry (AAS). For the selected mushrooms, concentration ranges (mg&middot;kg-1 total dry weight (dw)) of 46.90 - 141.80 for Cu, 0.10 - 6.60 for Cd, 1.10 - 2.00 for Pb, 19.00 - 38.90 for Zn, 1.00 - 3.40 for Ni, and 44.80 - 79.70 for Co were obtained. However, for the respective soil samples, concentration ranges (mg&middot;kg-1&middot;dw) of 51.00 - 279.40 for Cu, 1.00 - 99.50 for Cd, 8.00 - 10.00 for Pb, 22.80 - 209.10 for Zn, 9.00 - 33.70 for Ni, and 60.00 - 111.90 for Co were obtained. To a certain degree, the concentrations reflected the impact of diversity in the surrounding activities. This study discovered that for the selected mushrooms, the contamination level of cadmium, cobalt, nickel, and copper exceeded the World Health Organization (WHO)/FAO (Food and Agriculture Organization) recommended limits. Although some minor aberrations from the prescribed limits were also observed in the case of copper and nickel. Further, the data established that the heavy metal concentrations in respective soils are not the sole determinant of concentrations in mushrooms. Thus, these findings merit attention as, in some cases, the extent of contamination has exceeded the WHO permissible limit, and it may pose a health risk to consumers. 展开更多

Auricularis polytricha, Lentinus edodes, Agrocybe sp and Pleurotus flabellatus were grown under submerged culture and screened for endopolysaccharides. The fermentation was done in 250 ml working volume Erlenmeyer flask and the fermentation curves for all species were established. Pleurotus flabellatus has the highest rate of biomass production at the rate of 0.180 g/L/day, at 10 days hence chosen for further investigation. Two additional media, viz. Mushroom Complete Media (MCM) and Yeast Malt (YM) were selected to be compared with potato extract(PE) media used initially. MCM media produced the highest biomass productivity at the rate of 0.311 g/L/day. Pleurotus flabellatus biomass was extracted using modified Mizuno method and the endopolysaccharide obtained was tested for β-glucan. The yield of β-glucan was 7.70 ± 1.11 g/100g. The polysaccharides were purified using column chromatography to yield four fractions. The fourth fraction F4, gave the highest molecular weight at 3.058 × 106 Dalton (11.8%) and 1.282 × 104 Dalton (88.2%). The mushroom, P. flabbelatus was cultured using air-lift bioreactor, and the highest productivity was obtained at air-flowrate 2 L/min, yielding 2.25 g/L/day. The yield of biomass against substrate used (glucose consumption) Yb/s was 0.78 g/g. 展开更多

The Indian sub-continent is blessed with favorable agro climatic conditions that are suitable to a varied range of fungal species. Though the occurrence of mushrooms is of diverse nature, they are not well studied and documented. Northeastern region of India is one of the biodiversity hotspots. Nagaland is one of the Northeastern states of India. The people of the state highly covet mushrooms and have been a delicacy since time immemorial. The present study documents the macro fungal diversity in various districts of the state. A total of 87 species of wild mushrooms were collected and identified. They are parasitic, saprophytic and ecto-mycorrhizal in habitat. The highest numbers of mushroom species were collected during May–September from the study areas. Of the collected mushrooms, 37 species were identified as edible, 21 species medicinal, 5 poisonous and 37 inedible/unclassified. 展开更多

The effect of plasma-processed air(PPA)treatment with different conditions(time,power andflow rate)on the inactivation of Escherichia coli(E.coli)in button mushroom was evaluated.Response surface methodology(RSM)was applied to optimize PPA treatments on the E.coli of button mushrooms.According to the response surface analysis,the optimal treatment parameters were a treatment time of 12 min,treatment power of 90 W and flow rate of 1.2 l min-1.As with verifying tests from the optimization exercise,the number of E.coli reduced by 5.27 log CFU/g at the determined optimum conditions.The scanning electronic microscopy(SEM)micrography showed that the surface of the E.coli was significantly changed under the optimized PPA treatment.Quality parameters of button mushrooms treated at the determined optimum conditions were compared with untreated samples during the storage for 12 d at 4°C?±?1°C.The PPA treatment was found to be effective in inhibiting microbes and preserving postharvest quality in button mushrooms,and these results suggested PPA treatment may provide an alternative for the sterilization of foodborne and maintaining postharvest of fruits and vegetables. 展开更多

Every year mushroom wastes are produced in big volumes from edible mushroom production industries. Vermicomposting technology using earthworms as versatile natural bioreactors for effective recycling of organic wastes to the soil is an environmentally acceptable means of converting waste into nutritious composts for crop production. This study was undertaken to use earthworms (eisenia foetida) in vermicomposting on edible mushrooms wastes. The Randomized block design with three treatments in Kimia, Sabalan and Artashahr mushroom production industries were selected and four replications were applied for treatments. The total biomass of earthworms was estimated by counting the number of adults, juveniles and cocoons from each replication. The number of adult and mature worms, egg capsules and wet weight of earthworms were recorded in one month intervals (totally in five months). Vermicomposting was carried out by these worms in four months in spite of delay in their establishment in mushroom wastes. The worms wet weight, their number and the number of capsules were increased up to fourth month and then decreased. The produced vermicompost had suitable properties for amending soil. 展开更多

Eleven different wild-edible mushroom species growing in the Black Sea region of Turkey were analysed for their metal content. Specimens of mushrooms were gathered in Trabzon, Giresun and Ordu and analyzed for 31 minerals, four of which (Be, Sb, Te and Ti) were not detected. Whereas some minerals including Ag, As, Cd, La, Mo, Pb, Se, Y and Zr were detected in just a few mushroom species, another 18 minerals were found in all 11 species. All metal concentrations were expressed on a dry weight basis (d.w.). With regard to nutritionally important amounts of essential and trace minerals, the metal content (μg/g d.w.) of mushroom samples ranged from 21,800-39,800 for K, 2590-14,000 for P, 268-1600 for Ca, 561-1210 for Mg, 74-829 for Fe, 11.2-321 for Cu, 36.2-241 for Zn, 14.1-76.5 for Mn and 0.13-2.85 for Co. Small amounts of toxic metals such as As, Cd and Pb were found in all 11 mushroom species. L. laccata contained a large amount of As (145 μg/g d.w.). These results show that the investigated mushrooms can be a useful component for human diets because of their high content of many essential minerals and trace elements and low content of toxic metals. 展开更多
