Summary: Pleurotus ostreatus mushroom is rich in bioactive compounds that have both antimicrobial and prebiotic properties. These compounds help support a healthy gut microbiota and reduce the risk of antibiotic resistance. Furthermore, the mushroom also exhibits antibacterial, antiviral, and antifungal activities. Therefore, consuming a diet rich in P. ostreatus mushrooms can improve digestive health.

Summary: In this study, the effects of corn straw and xylosma sawdust on the production and activity of polysaccharides by edible fungi during solid-state fermentation were investigated using Lentinula edodes and Pleurotus ostreatus as representatives. The results showed that the addition of lignocellulose promoted the polysaccharide content compared to the control group. The hydroxyl radical scavenging activity of polysaccharides reached the maximum at a glucose concentration of 1.5%, with xylosma sawdust groups performing better than corn straw groups.

Summary: The study found that polysaccharides extracted from oyster mushrooms using subcritical water at 180 degrees Celsius yielded the highest recovery rate and exhibited better anticoagulant activity after sulfation. Sulfated polysaccharides significantly improved clot formation inhibition activity and showed low cytotoxicity, suggesting their potential as an alternative for anticoagulant therapy.

Summary: This study evaluated the potential of oyster mushroom powder (OMP) as a phosphate alternative to improve the emulsion stability of emulsion-type sausage. OMP addition improved physicochemical properties of the sausage, prevented lipid oxidation, and delayed bacterial growth during cold storage. The emulsion stability promoted by OMP was mainly attributed to polysaccharides, enhancing viscosity and steric hindrance.

Summary: The structure of a selenium-enriched polysaccharide, Se-POP-21, was characterized and its immunomodulatory activity was investigated. The polysaccharide was found to enhance cell proliferation and phagocytosis, increase expression of costimulatory molecules, and induce secretion of immune-related molecules. This study suggests the potential application of Se-POP-21 in immunomodulatory drugs or functional foods.

Summary: Dietary administration of POPS can affect the activity of antioxidant and immune related enzymes in A. japonicus, as well as alter gut microbiota diversity. The relative abundance of dominant gut microbiota populations Proteobacteria and Bacteroidetes can change, with an increase in Chloroflexi observed after POPS supplementation. Additionally, distinct differences in gut microbe composition were observed in the POPS3 group compared to other groups.

Summary: Solid-state fermentation (SSF) is a bioprocess that can produce protein-vegetal ingredients with increased nutritional and functional value. This study evaluated the changes in various parameters during the SSF process of Pleurotus ostreatus in lentils and quinoa. The results showed that fungus biomass and protein content increased during fermentation, while the soluble protein fraction remained constant. SSF also had a positive impact on reducing antinutrient content and promoting antioxidant activity. However, these parameters decreased as fermentation progressed.

Summary: This research optimized the extraction parameters for maximizing the antioxidants of mushrooms. The total antioxidant status (TAS) and total oxidant status (TOS) of mushrooms under different extraction parameters were determined. Artificial neural network (ANN) and multiobjective particle swarm optimization (MOPSO) were used for modeling and optimization of the extraction process. The developed ANN-MOPSO hybrid model accurately predicted and optimized the TAS and TOS values of Pleurotus ostreatus extracts.

Summary: Through comparative transcriptome analysis, differences in the response of Pleurotus ostreatus and Pleurotus cornucopiae to Cd contamination were identified, including differences in Cd accumulation, removal rates, and expression of differentially expressed genes. Functional categories and pathways involved in Cd detoxification also differed between the two species, providing new insights into the molecular mechanisms of mycoremediation and accumulator screening.

Summary: This study investigates the non-canonical roles of telomerase reverse transcriptase (TERT) in Ganoderma lucidum, using RNA interference to silence the GlTert gene. The results show that GlTert plays a crucial role in fungal growth, oxidative stress response, and ganoderic acid (GA) biosynthesis in G. lucidum.

Summary: This study found that Salicylic acid (SA) treatment increased the cytosolic trehalose content and induced fungal resistance to heat stress (HS) in P. ostreatus. Further analysis showed that SA can alleviate the HS of P. ostreatus by reducing the intracellular ROS level and increasing the cytosolic trehalose content. These results help to understand the mechanism underlying the responses of P. ostreatus to HS and provide new insights for its cultivation.
