Summary: This study evaluated the feasibility of preparing papery food using Pleurotus eryngii as a raw material through the papermaking process. The results showed that PSP and PMP were more popular among consumers in terms of formability, mouth feel, and overall palatability, with PSP also exhibiting better moisture resistance and thermal decomposition performance.

Summary: This study proposes a rapid detection method for different growth stages of Pleurotus eryngii mycelium based on the characteristics of near-infrared spectroscopy. The method uses multivariate scattering correction and competitive adaptive reweighted sampling algorithms to establish a mathematical model between the mycelium and the characteristic wave number. The results show a 99.67% accuracy in identifying different growth stages of Pleurotus eryngii mycelium.

Summary: This study demonstrates that WPEP-N-b, a heterogalactan from Pleurotus eryngii, enhances immunity in immunosuppressed mice. WPEP-N-b improves immune organ index, peripheral blood immune cell content, splenocyte proliferation, NK cell activity, and T lymphocyte subpopulations. Additionally, WPEP-N-b restores cytokine levels and macrophage activity, and its mechanisms involve Toll-like receptor and signaling pathways.

Summary: This study evaluated the antioxidant and neuroprotective activity of an enriched polysaccharide fraction (EPF) obtained from the fruiting body of cultivated P. eryngii. The EPF showed high content of (1-3; 1-6)-beta-D-glucans and exhibited significant scavenging activities against DPPH, superoxide, hydroxyl, and nitric oxide radicals. It also demonstrated biocompatibility and reduced oxidative stress in DI-TNC1 cells. These findings suggest that polysaccharides extracted from P. eryngii could be used as functional food to enhance antioxidant defenses.

Summary: The study demonstrated that the mycelium of Pleurotus eiyngii obtained from in vitro cultures can effectively degrade various sulfonamide drugs without inhibiting its own growth. The degradation process showed biocompatibility and the transformation products included simpler organic compounds.

Summary: This study investigates the incorporation of mycelium into pea protein isolate to create a low moisture meat analogue. The addition of mycelium resulted in changes in color attributes and increased water solubility index, water absorption capacity, and oil absorption capacity. Protein solubility initially decreased and then increased, while water holding capacity and volumetric expansion ratio increased with the addition of mycelium, except for 40% incorporation. The fibrous and porous meat analogue produced showed potential in the plant-based product market and reducing the carbon footprint of food production activities.

Summary: Polysaccharides from P. eryngii mushroom were extracted using low-cost technologies, resulting in different fractions with immunostimulatory properties on THP-1 macrophages. The main polysaccharides included Mannogalactan and various β-glucans, which were not cytotoxic and induced different cellular responses. This simple technique allows the obtainment of fractions with distinct immunomodulatory activities, showing the potential for future biological effects research.

Summary: The study focuses on the domestication of Pleurotus spp., Pleurotus eryngii var. ferulae, and Pleurotus eryngii var. elaeoselini, and evaluates different media and substrates for their cultivation. Malt Extract Agar is found to be more suitable than Potato Dextrose Agar for domestication. T5 (50% wheat straw + 50% cardboard) and T8 (75% wheat straw + 25% spent coffee grounds + 5% wheat bran) show the best results for Pleurotus eryngii var. elaeoselini and Pleurotus eryngii var. ferulae cultivation respectively.

Summary: This study demonstrated that the combination of ssPOXA3a/b with POXA3 enhances the activity, thermostability, and pH stability of POXA3, while having a negative feedback effect on lacc6 transcription. Furthermore, overexpression of ssPOXA3a/b led to small fungal pellets, thin mycelial walls, and facilitated laccase secretion, providing insights for the development of high-yield laccase.

Summary: This study introduced pomegranate peel polyphenols embedded in chitosan to prepare antibacterial nanofibers, showing effective inhibition of bacterial growth on food surfaces (e.g. E. coli) without affecting food quality. By adding different concentrations of polyphenols and polysaccharides, the properties of nanofibers can be controlled to enhance encapsulation rate and tensile strength.

Summary: In this study, the structure of Pleurotus eryngii polysaccharides (PEPs) was characterized, and the mechanism of PEP on obesity and hyperlipidemia induced by high-fat diet was evaluated by metabonomic analysis. The results showed that PEPs could significantly reduce blood lipids and prevent and treat obesity and hyperlipidemia caused by a high-fat diet by regulating amino acid metabolism, fatty acid metabolism, and metabolic pathways such as the citric cycle (TCA cycle). Therefore, PEPs may be used as a functional food adjuvant for the prevention and treatment of high-fat diet-induced obesity and hyperlipidemia.

Summary: The study found that Pleurotus eryngii can improve postprandial blood sugar levels and appetite sensations in obese individuals, while also regulating ghrelin levels. This effect may be attributed to the bioactive polysaccharides in Pleurotus eryngii, which inhibit the activity of enzymes catalyzing carbohydrate hydrolysis, causing delayed gastric emptying and glucose absorption.

Summary: Although mushroom production is sterile, bacterial communities associated with the process have been identified. Through biochemical and molecular methods, bacterial species present during each stage of Pleurotus eryngii culture were isolated and identified. Enterobacteriaceae and Bacillaceae were the predominant families, including Bacillus subtilis, B. tequilensis, B. cereus, Ewingella americana, and Klebsiella grimontii. The inhibitory effect of Klebsiella grimontii and Bacillus cereus on the growth of Pleurotus eryngii var. ferulae mycelium was significant.
