Immunomodulatory effects of polysaccharides from edible fungus:a review

The polysaccharides from edible fungus showed many kinds of biological activities,including anti-tumor,immunomodulatory,anti-inflammatory,anti-diabetes,improving functional constipation activities.In particular,the immunomodulatory effects have been paid more and more attention by scholars,but there was no systematic introduction of their immunomodulatory mechanism.So,this review introduced the immunomodulatory effects and mechanism of edible fungus polysaccharides in recent years,and then the relationships between structure and immunomodulatory effect were also discussed.

Therapeutic effect of natural melanin from edible fungus Auricularia auricula on alcohol-induced liver damage in vitro and in vivo

This study explored the therapeutic effects of Auricularia auricula melanin(AAM)on alcoholic liver damage in vitro and in vivo.Human normal liver L02 cells were pre-treated with ethanol and then treated with AAM to explore the therapeutic effect of AAM on ethanol-induced hepatocyte injury.The results show that AAM signifi cantly elevated the cell viability,ameliorated the cell morphology,reduced the ROS and increased the GSH/GSSG of ethanol-pretreated L02 cells.Then,mice were administered with ethanol to induce acute alcoholic liver damage,and administered with AAM to further study the therapeutic effect of AAM on alcoholic liver damage in mice.As a result,AAM reduced the levels of ALT,AST,TG,and MDA,increased the levels of ADH,SOD,and CAT in liver damage mice.The therapeutic effect of AAM may be related to inhibition of CYP2E1 expression and activation of Nrf2 and its downstream antioxidase.The research enriched the bioactivity of AAM and provided some ideas for the development of melanin-related health foods.

rDNA Sequencing and Preliminary Analysis of Microorganisms from Diseased Edible Fungus Using Non-culture Technology

The metagenomic DNA of disease tissue samples from four kinds of major edible fungus was extracted by CTAB method combined with DNA gel recovery kit. The genomie DNA was amplified by polymerase chain reaction using the universal primers of 16S rDNA and 18S rDNA, and then mone, elonal sequenced after ligated and transformed, rDNA sequences of 20 positive clones were selected randomly from each pair of primers for sequence alignment. The results showed that there were two bacterial diseases and two fungul diseases in the samples, respectively.

Current Development Situations and Countermeasures of Edible Fungus Industry in Heilongjiang Province in the Context of Rural Revitalization

The rise of the edible fungus industry has not only greatly increased the income of Chinese farmers,but also promoted the economic,social and ecological development of rural areas.Through a survey of the edible fungus industry in Heilongjiang Province,it found problems such as insufficient standardized production bases,insufficient coverage of"Internet+edible fungi",weak industrial clusters,conservative management ideas,and lack of professional talents.The development potential of edible fungi was analyzed and reasonable recommendations were put forward to promote the healthy,efficient and sustainable development of the edible fungus industry in Heilongjiang Province.

A high-loading and cycle-stable solid-phase conversion sulfur cathode using edible fungus slag-derived microporous carbon as sulfur host

Developing a high sulfur(S)-loading cathode with high capacity utilization and long term cyclability is a key challenge for commercial implementation of Li-S battery technology.To overcome this challenge,we propose a solid-phase conversion sulfur cathode by using an edible fungus slag-derived porous carbon(CFS)as sulfur host to fabricate the S/CFS composite and meanwhile,utilizing the vinyl carbonate(VC)as co-solvent of the ether-based electrolyte to in-situ form a protective layer on the S/CFS composite surface through its nucleophilic reaction with the freshly generated lithium polysulfides(LiPSs)at the very beginning of initial discharge,thus isolating the interior sulfur from the outer electrolyte and inhibiting the further generation of soluble LiPSs.Benefitting from the ultrahigh specific surface area of>3,000 m^(2)·g^(−1),ideal pore size of<4 nm,and large pore volume of>2.0 cm^(3)·g^(−1)of the CFS host matrix,the S/CFS cathode even with a high S-loading of 80 wt.%(based on the weight of S/CFS composite)can still operate in a solid-phase conversion manner in the VC-ether co-solvent electrolyte to exhibit a high reversible capacity of 1,557 mAh·g^(−1),a high rate capability with 50%remaining capacity at 2 A·g^(−1)and a high cycling efficiency of 99.9%over 500 cycles.The results presented in this work suggest that a combined action of solid-phase conversion electrochemistry and nanoarchitectured host structure may provide a new path for the design and development of practical lithium-sulfur batteries.

Effects of Extract of Medium Residue from Cultivation of Pleurotus citrinopileatus on Mycelial Growth of 3 Edible Fungi

Effects of extract of medium residue of Pleurotus citrinopileatus on mycelial growth of P. citrinopileatus, G. lucidum and L. edodes were investigated by plate cultivation method. The results showed that extract of medium residue of P. citrinopileatus promoted mycelial growth of L. edodes, and showed the best effects at the addition amount of 75%, while the myedial growth of G. lucidum and P. citrinopileatus was inhibited by the extract.
