Abstract ：
In producing active probiotic powder, the encapsulant impacts the viability and functionality of dehydrated bacteria through various mechanisms, which may exhibit synergistic or antagonistic effects. This study investigated the effects of supplementing a water-soluble antioxidant to non-fermentable disaccharide lactose or fermentable disaccharide trehalose as encapsulants for producing Lacticaseibacillus rhamnosus GG (LGG) powders via spray drying. LGG powders prepared with pure sugar encapsulants exhibited inactivations of 0.68-1.02 log, whereas incorporating 0.5 wt% antioxidants significantly increased viability loss, with inactivation levels reaching 1.08-1.71 logs for epigallocatechin gallate (EGCg) and 4.03-4.52 logs for ascorbic acid (AA). More intensive inactivation was observed for trehalose-based powders than for lactose-based powders. The powders showed minimal changes in antioxidant capacity, indicating neutralized oxidative stress during spray drying. The particle morphology and the thermal and hygroscopic properties of LGG-encapsulating powders were minorly affected by the antioxidants. However, LGG cells in antioxidant-supplemented powders bore substantial injuries on growth capability, membrane integrity, and cellular shape. Incubating LGG with each antioxidant confirmed their antibacterial effects in sugar solutions, with EGCg being more inhibitory than AA. 1H NMR revealed the electron-donating behavior of EGCg when interacting with LGG, potentially disrupting the bacteria's metabolic system. AA caused a shift in three out of seven LGG signal peaks toward the low field, and it might induce additional acid stress during dehydration. The findings elucidated the multiple pathways that antioxidative agents interact with LAB during dehydration, including altering the intensity of dehydration-associated stresses, modifying the physicochemical properties of particles, and interfering with cellular activities.

Abstract ：
Tremella fuciformis is an important edible and medicinal fungi in China, and it can undergo the dimorphic transition between yeast-like conidia and mycelia form, which is particularly crucial in the production and breeding. As a companion fungus, Annulohypoxylon stygium plays a crucial role in the dimorphic transition of T. fuciformis, and previous study found A. stygium extract can promote yeast-like conidia transit to mycelium, but the mechanism is still unclear. This study determined an optimal concentration of the A.stygium extract for promoting the germination and mycelia growth of T. fuciformis. Time-course proteomics was used to characterize the dynamic changes in protein expression during the dimorphic transition within 72 h. A total of 2095 proteins were differentially expressed, which involved in biological processes such as MAPK signaling pathway, starch and sucrose metabolism. Further bioinformatics revealed that MAPK signaling pathway played the most crucial role, among which TfSte7 gene was the hub gene, during yeast-like conidia transit to mycelium. Molecular biological studies demonstrated that the TfSte7 gene can shorten the germination time and promote mycelial growth in T. fuciformis. This study provides an important molecular basis for deeper understanding of the interaction mechanism between A. stygium and the dimorphic of T. fuciformis.

Abstract ：
Tremella fuciformis Berk., also known as white fungus and snow fungus, is one of the important edible and medicinal mushrooms in China. The quality characteristics and metabolites of different T. fuciformis varieties directly affect the stability of their processed products. In this study, two new varieties of Tremella fuciformis, namely 'TYH-SD1' (yellow) and 'TWH-SD2' (white), which were obtained by the team through single-spore crossbreeding and its control varieties Tr21 (yellow) and Tr01 (white), were used as test materials. The characteristics and nutritional quality of the four varieties of substrates were comparatively analyzed, while metabolomics was employed to investigate the differences in flavor substances. The results demonstrate that TYH-SD1 and TWH-SD2 had a higher rehydration rate and faster rehydration speed compared with the control strains Tr21 and Tr01, with a smaller stem and higher yield. Notably, TWH-SD2 had a 29.06% increase in its rehydration rate and it had higher contents of crude polysaccharide and vitamin D3. The surface of TYH-SD1 ear pieces exhibited a porous structure with a larger pore size and the surface of TWH-SD2 ear pieces displayed a surface characterized by connected gully-like protrusions and fewer indentations, which were significantly different from that of Tr21 and Tr01 ear pieces. The textural analysis shows that TYH-SD1 and TWH-SD2 ear pieces were softer and more elastic, with greater cohesion and recovery, indicating that they had high tensile and deformation recovery ability. Metabolomics analysis revealed that the relative content of aldehydes in the volatile flavor substances TYH-SD1 and TWH-SD2 was high in n-alpha-aldehyde, nonanaldehyde, and n-pentanal. The relative content of alkanes in TYH-SD1 was second only to that of aldehydes, with decane having the highest content, contributing to its more almond aroma, fruity aroma, and fat aroma. TWH-SD2 exhibited the highest concentration of alcohols, accounting for 43.57%, which may result in a clear, mushroom, and lipid odor. The above results will provide theoretical basis for the further production, processing, and application of the new varieties.

Abstract ：
A bioactive Pleurotus eryngii aqueous 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 than P. eryngii polysaccharide (PEP). Meanwhile, a typical absorption peak observed at 843 cm(-1) in the SPAE FTIR spectra indicated the existence of alpha-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-producing Akkermansia and reduced the abundance of Ruminococcus and Clostridiides in intestines of mice. These results show the potential of SPAE as a novel material with prebiotic effects for the food and pharmaceutical industries.

Abstract ：
The composition of culture substrate is an important environmental factor that affects the growth and metabolism of Hypsizygus marmoreus, and sawdust is commonly used as the substrate for cultivating mushrooms. However, the influences of sawdust on metabolic level of H. marmoreus in mycelial growth is little reported. In this study, the effect of sawdust addition on mycelial growth rate, morphological characteristics and nutrient content of H. marmoreus was explored, and the metabolic response was analyzed based on LC-MS/MS. The results showed the mycelial growth rates and the number of mycelial clamp connections in sawdust medium A and sawdust medium B were significantly higher than that of the basic medium (Control). The mycelial morphology in sawdust medium A was denser, with higher edge trimness and stronger aerial mycelia. The contents of crude fiber, crude protein and polysaccharide of the mycelia from sawdust medium A increased by 85.15%, 90.65% and 92.61%, respectively, compared to that in the basic medium. A total of 551 metabolites were identified and obtained. The differential accumulated metabolites (DAMs) were mainly amino acids, lipids compounds and carbohydrates. It was speculated that the addition of sawdust played a vital role in promoting the cell division and, thus, the formation of clamp connections in H. marmoreus mycelia. Regarding amino acids, the metabolism of glycine, serine and ABC transporters was active with the increase in sawdust, thereby increasing the protein content. And some valuable bioactive molecules were found, such as docosahexaenoic acid (DHA). This study will lay the foundation for further research on the substance transformation and quality improvement of cultivation substrate for mushrooms.

Abstract ：
银耳胶(Tremella fuciformis gum,TFG)是一种采用新鲜银耳子实体加工得到的新型真菌胶体,相比经由复杂提纯步骤制备的银耳多糖产品,具有性价比高、方便携带和生产成本低等优点。本文分别从理化特性、流变行为和体外消化行为三个方面对TFG的进行研究。研究结果表明:TFG是一种以银耳多糖为主要成分(73.9%)的胶体,含有少量蛋白质(5.5%)和还原糖(1.67%),具有良好的胶体特性和稳定性。在加工中,可以通过物理或化学方法处理降低TFG溶液的表观粘度。TFG具有较好的抗氧化活性,其抗氧化活性在每个静态体外仿生消化阶段均保持不变,表明TFG可作为一种潜在的食品增稠剂和抗氧化剂应用于食品、化妆品和医药工业。TFG在动态体外仿生消化系统(Dynamic in vitro rat stomach-intestinal system-Ⅱ,DIVRS-Ⅱ)中的消化行为应归因于消化道的形态、消化液分泌和排空行为。动物实验表明,TFG具有镇咳作用,可能与服用TFG后小鼠血清中的IL-10含量升高有关。

Abstract ：
Hypsizygus marmoreus has become one of the most popular edible mushrooms due to its high nutritional and economic value. Previous researchers found that Serratia odorifera could promote the growth of H. marmoreus by producing and secreting some of its inducers. However, the specific mechanism of action was still unclear. In this study, we found that the exogenous addition of sterile fermentation filtrate (HZSO-1), quorum sensing (QS) signaling molecules, 3-oxo-C-6-HSL, cyclo(Pro-Leu), and cyclo(Tyr-Leu) could significantly promote the growth of H. marmoreus, increase the number of clamp junctions, and the diameter of mycelium (p < 0.05). In addition, non-targeted metabolomic analysis revealed that 706 metabolites were detected in the treated group. Of these, 307 metabolites were significantly different (p < 0.05). Compared with the control, 54 and 86 metabolites were significantly increased and decreased in the HZSO-1 group, respectively (p < 0.05). We speculate that the sterile fermentation filtrate of S. odorifera could mediate the carbohydrate and amino acid metabolism of H. marmoreus by influencing the pentose phosphate pathway (PPP) to increase the energy supply for the growth and development of the mycelium. The above results will further reveal the growth-promoting mechanism of S. odorifera on H. marmoreus.

Abstract ：
Depolysaccharide residues of edible fungus Pleurotus eryngii (dePSR-Pe), a mushroom industry waste, have abundant cellulose. In this study, the cellulose nanocrystals of P. eryngii (PeCNs) were extracted by hydrochloric acid. Results showed that the length of PeCNs is 469 +/- 76.41 nm with a high aspect ratio of 40-100 and needle morphology. The structural characterization revealed that PeCNs had good thermal stability (approach 300 degrees C) and high crystallinity (84.2 %). An O/W Pickering emulsion stabilized with PeCNs was prepared to inhibit lipid oxidation and improve the loading capacity of triterpenes of P. coco. Unimodal size distribution of emulsion droplets was obtained under an optimized aqueous-phase condition to form a metastable emulsion, regardless of varying oil-water volume ratio <50/50. In vitro digestion study suggested that triterpenes-loaded Pickering emulsion had 1-3 times higher drug stability than bulk oil. These metastable Pickering emulsions call for fewer nanoparticles and provide a new strategy for the industry application of cellulose nanocrystals at less cost.

Abstract ：
Global mushroom production is growing rapidly, raising concerns about polluting effects of spent mushroom substrate (SMS) and interest in uses in composts. In this study, SMS composting trials and high-throughput sequencing were carried out to investigate to better understand how the structure, co-occurrence patterns, and functioning of bacterial and fungal communities vary through compost time and across environmental conditions. The results suggested that both bacterial and fungal microbiota displayed significant variation in community composition across different composting stages. Enzyme activity levels showed both directional and fluctuating changes during composting, and the activity dynamics of carboxymethyl cellulase, polyphenol oxi-dase, laccase, and catalase correlated significantly with the succession of microbial community composition. The co-occurrence networks are "small-world" and modularized and the topological properties of each subnetwork were significantly influenced by the environmental factors. Finally, seed germination and seedling experiments were performed to verify the biosafety and effectiveness of the final composting products.
