A bioactivePleurotus eryngiiaqueous extract powder (SPAE) was obtained by spray drying and its performance in terms of physicochemical properties, in vitro digestion, inflammatory factors, and modulation of the intestinal microbiota was explored. The results indicated that the SPAE exhibited a more uniform particle size distribution thanP. eryngiipolysaccharide (PEP). Meanwhile, a typical absorption peak observed at 843 cm−1in the SPAE FTIR spectra indicated the existence of α-glycosidic bonds. SPAE exhibited higher antioxidant abilities and superior resistance to digestion in vitro. In addition, SPAE supplementation to mice significantly reduced the release of factors that promote inflammation, enhanced the secretion of anti-inflammatory factors, and sustained maximum production of short-chain fatty acids (SCFAs). Additionally, it significantly enhanced the relative abundance of SCFAs-producingAkkermansiaand reduced the abundance ofRuminococcusandClostridiidesin intestines of mice. These results show the potential of SPAE as a novel material with prebiotic effects for the food and pharmaceutical industries.

N and B co-doped carbon materials were prepared using urea and H 3 BO 3 as activators and Pleurotus eryngii as the carbon source. Structural characterization shows that the heteroatom content of PENB (co-modified by urea and H 3 BO 3 ) is as high as 62 %, which is much higher than that of carbon materials modified by a single activator. The specific surface area of PENB is 2.2 times that of PEB (modified only by H 3 BO 3 ) and 127.4 times that of PEN (modified only by urea). The high specific surface area of PENB can provide more active sites. The excellent structure of PENB can be attributed to the fact that urea and H 3 BO 3 retain heteroatoms in the reaction system through neutralization reaction, which promotes the contact between heteroatoms and biomass, thereby enhancing the etching effect of heteroatoms on carbon materials. In addition, N and B atoms can induce amorphous carbon materials to produce graphene microcrystals, which can enhance the electronic conductivity of PENB. Interestingly, this method of increasing the content of heteroatoms and generating graphene is also applicable to other biomass. Electrochemical tests show that PENB exhibits the highest electrochemical performance. The symmetrical supercapacitor (SSC) assembled with PENB has an energy density of 8.8 Wh kg −1 at a power density of 400 W kg −1 . After 10,000 cycles, the capacitance retention rate is 100 %. This work provides a new universal strategy to improve the heteroatom content of carbon materials and the preparation of graphene, which can well cope with the energy crisis.

BFPS and EBFPS improved growth performance, feed utilization, and serum immunity. • EBFPS showed better potential in improving intestinal morphology and microbial homeostasis than BFPS. • EBFPS activated TLRs signaling and inhibited intestinal inflammation, while conversely in BFPS. A 56-day feeding trial was carried out to compare the effects of king oyster mushroom ( Pleurotus eryngii ) and soybean meal (SM) fermented by microorganisms ( Saccharomyces cerevisiae Sa, Bacillus pumilus SE5, and Lactobacillus lactis 17, BFPS) alone or in combination with enzymes (cellulase and protease, EBFPS) on growth performance, serum biochemistry, and intestinal health in large yellow croaker ( Larimichthys crocea ). Large yellow croaker was randomly assigned to three groups (control, BFPS, and EBFPS) with four replicates (160 fish per replicate) per group. Results showed that BFPS and EBFPS improved growth performance and feed utilization, but did not affect organ-somatic indices. Dietary BFPS and EBFPS decreased serum aspartate transaminase and alanine transferase activities, implying superior liver health of croakers. Moreover, there were significant enhancements of serum alkaline phosphatase and acid phosphatase activities in BFPS and EBFPS groups, as well as immunoglobulin M content in EBFPS group. In terms of inflammatory cytokines, serum IL-1β and TGF-β1 contents were reduced in croakers fed with BFPS-contained diet, while croakers fed with EBFPS-contained diet showed reduction of serum IL-1β content, but not TGF-β1. Dietary BFPS decreased MT, VH, VW, and expressions of occlidin and jam , while enhanced MT, VH, VW, and zo-1 mRNA level were observed in fish fed with EBFPS-contained diet. Dietary BFPS resulted in significant up-regulation of pro-inflammatory il-1β and il-6 mRNA levels, as well as significant down-regulation of il-4/13a , il-4/13b , il-10 and tgf-β1 , tlr1 and tlr2b mRNA levels. Inconsistently, dietary EBFPS up-regulated il-4/13a , il-10 , tlr1 , tlr2a , and tlr2b mRNA levels. EBFPS, rather than BFPS, increased α-diversity of intestinal microbiota, and β-diversity revealed that the cluster of the EBFPS group was notably separated from the control and BFPS groups' cluster. Furthermore, the enhancement of beneficial Firmicutes and the reduction of pathogenic Proteobacteria and Brevinema were observed in croakers fed with EBFPS-contained diet. BFPS increased Proteobacteria and reduced Brevinema . Overall, EBFPS, as a functional protein source, could efficiently improve growth, immunity, and intestinal health of large yellow croaker ( L. crocea ) compared to BFPS.

It is critical to prepare self-supported carbonaceous electrode materials that enable high-mass loading and efficient ion/electron transport through a simple and sustainable method. Herein, for the first time, heteroatom-doped (O, N, and S) hierarchically porous thick bulk carbon is synthesized by carbonizing Pleurotus eryngii (PE) and lignosulfonate (LS) mixed precursors. After carbonization, the generated thick bulk carbon consists of interconnected macropores at the micrometer scale, with micropores and mesopores densely covering the pore walls. The carbon material displays a large specific surface area ranging from 315.5 to 960.2 m2 g−1 and is uniformly doped with O (14.8–19.1%), N (1.73–2.97%) and S (1.20–1.94%), endowing it with excellent ion transport and charge storage properties. As a result, the obtained thick bulk carbon electrode with a mass loading of 58.0 mg cm−2 achieves an outstanding capacitance of 25.0 F cm−2 (112.0 F cm−3) at 10 mA cm−3 and a superior rate capability of 14.3 F cm−2 (66.9 F cm−3) at 200 mA cm−3. The assembled symmetric supercapacitor device delivers a high areal energy density of 2.56 mWh cm−2 at a power density of 0.64 mW cm−2 with an excellent stability of 91.1% after 15 000 cycles at 50 mA cm−2. This facile and green synthesis strategy provides new carbonaceous electrode design concepts for high-energy-density storage.

Pleurotus eryngii protein is considered high quality protein based on its rich and comprehensive essential amino acids, and has also been proved displaying multiple significant functional characterizations of which vary with its fabrication process. We aimed to investigate the variation differences of P. eryngii protein extracted by alkaline extraction and acid precipitation (AA), cellulase complex alkaline extraction and acid precipitation (CAA), ultrasound assisted alkaline extraction and acid precipitation (UAA), and salt dissolution method (S) from the perspective of gastrointestinal digestion and fecal fermentation consequences. Protein hydrolysis and structural analysis was performed on after in vitro gastrointestinal digestion, and found that AA had the highest hydrolysis degree while CAA had the lowest. The results of fluorescence chromatography and infrared chromatography indicated that the reasons for the digestion difference might be the unfolding degrees of protein tertiary structure and the polysaccharide which was the highly contained component in crude protein and had the opportunity to prevent protein hydrolysis. Metagenomic analysis suggested that compared with other groups, AA had excellent biological functions including regulating obesity and insulin related microbiota. This study could provide new theoretical basis for the P. eryngii protein as a novel type of nutrient and functional component, and contribute to the development of constructing a diversified emerging food protein supply system.
