Fermentation markedly increased inhibitory activity, with the freeze-dried crude supernatant exhibiting an IC50 of 2.115 mg/mL. Activity was further enriched through stepwise purification: ultrafiltration (<3 kDa) improved potency (IC50 = 1.206 mg/mL), and subsequent Sephadex (crosslinked dextran) G-15 gel filtration yielded a more active E fraction (IC50 = 1.145 mg/mL). LC–MS/MS characterized 19 peptides, and integrated in silico screening (PeptideRanker combined with molecular docking) highlighted GEPGPEGPAG as a leading candidate, showing a more favorable predicted binding energy (−82.50 kcal/mol) than the positive control acarbose (−69.31 kcal/mol). Docking analysis suggests that GEPGPEGPAG may inhibit α-glucosidase by forming a stable network of hydrogen bonds, salt bridges, and hydrophobic interactions within the catalytic pocket. Overall, DS31-fermented whey and its enriched fractions show promise as functional ingredients for postprandial glycemic control.","PeriodicalId":507249,"journal":{"name":"Fermentation","volume":"12 2","pages":"74-74"},"PeriodicalIF":0.0,"publicationDate":"2026-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.mdpi.com/2311-5637/12/2/74/pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147381629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Kelch-like ECH-associated protein 1–nuclear factor erythroid 2-related factor 2–heme oxygenase-1/glutathione peroxidase 4 signaling pathway (Keap1–Nrf2–HO-1/GPX4) signaling pathway is a key target for regulating hepatic antioxidant defense. This study integrated Ultra Performance Liquid Chromatography-Tandem Mass Spectrometry (UPLC-MS/MS), Global Natural Products Social Molecular Networking (GNPS) molecular networking, network pharmacology, and animal experiments to systematically explore the hepatoprotective effect and mechanism of Cornus officinalis yeast-fermentation (COF). Component characterization identified 25 bioactive components, including flavonoids, triterpenic acids, and other fermentation-derived metabolites. Network pharmacology identified 441 common targets and 36 core targets of COF and ALI, which were enriched in oxidative stress regulation, inflammatory response, and the Keap1–Nrf2 pathway via Gene Ontology (GO)/Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis. Molecular docking showed that icariin and other components had stable interactions with Keap1 and Nrf2 (binding energy < −5 kcal/mol). Animal experiments confirmed that COF reduced the liver index of ALI mice, downregulated serum Alanine Aminotransferase (ALT)/Aspartate Aminotransferase (AST) activities, and ameliorated liver pathological damage. Western blot verified that COF inhibited Keap1 expression, promoted Nrf2 nuclear translocation, and upregulated HO-1/GPX4 expression. In conclusion, COF alleviates hepatic oxidative stress by regulating the Keap1–Nrf2–HO-1/GPX4 pathway, providing a scientific basis for its development as a functional food or candidate drug against ALI and a technical paradigm for fermentation-enhanced medicinal plant research.","PeriodicalId":507249,"journal":{"name":"Fermentation","volume":"12 1","pages":"28-28"},"PeriodicalIF":0.0,"publicationDate":"2026-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147381472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compared with the AM group, the HR group exhibited increased serum activities of SOD (20.26%), GSH-Px (9.03%), and CAT (133.01%), with a 24.87% decrease in MDA level. In brain tissue, SOD, GSH-Px, and CAT activities increased by 79.49%, 8.45%, and 60.23%, respectively, while MDA decreased by 8.29%. R. mucilaginosa JAASSRY also dose-dependently alleviated structural damage in the hippocampus and spleen and improved motor strength and learning-memory capacity. Furthermore, R. mucilaginosa JAASSRY increased the abundance of Lactobacillus and reduced Proteobacteria, Helicobacter, and Oscillospira, while enhancing antioxidant capacity by modulating nucleotide, lipid, and carbohydrate metabolism. Lactobacillus and Pediococcus were positively correlated with memory latency and CAT/SOD activities (p < 0.05), whereas Actinormyces and Dehalobacterium showed negative correlations. Notably, HR performed comparably or superiorly to β-carotene in improving cerebral oxidative stress and beneficial microbiota, suggesting its potential in neuroprotection and gut–brain axis regulation.

However, its industrial production is hindered by the low catalytic efficiency (≤33% conversion) and unfavorable equilibrium of the key enzyme, D-allulose 3-epimerase (DAE). To overcome this thermodynamic bottleneck, an in vitro synthetic enzymatic cascade based on a phosphorylation–dephosphorylation strategy was constructed. This engineered system comprises four synergistically operating enzymes: D-allulose-3-epimerase (DAE), L-rhamnulose kinase (RhaB), polyphosphate kinase (PPK), and acid phosphatase (AP). Through rational design and systematic optimization, the cascade achieved an exceptional 84.5% conversion yield from 50 mM D-fructose. Importantly, the system also maintained high conversion rates of 64.4% and 61.1% at high D-fructose loadings (50–100 g L−1).

Solid-state fermentation (SSF) offers a strategy to enhance their bioactivity, yet triple microbial co-fermentation remains underexplored. This study applied a triple microbiota—featuring Aspergillus niger (A. niger), Bacillus subtilis (B. subtilis), and Saccharomyces cerevisiae (S. cerevisiae)—to ferment the stems and leaves of both plants. Antibacterial activity against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) was assessed via the Kirby–Bauer test, while Liquid Chromatography–Tandem Mass Spectrometry (LC–MS/MS)-based non-targeted metabolomics identified differential metabolites and enriched pathways. Co-fermentation significantly increased the inhibition zones to 17.4 ± 0.8 mm for E. coli and 17.7 ± 0.3 mm for S. aureus, a 1.8-fold improvement over the unfermented controls (p < 0.001). Among the 2976 metabolites detected, 1236 were differentially expressed, with Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis highlighting activation of aminoacyl-tRNA biosynthesis, ABC transporter, and phenylalanine–tyrosine–tryptophan pathways. Differential abundance analysis indicated that the aminoacyl-tRNA pathway (DA score > 0.9) is critical for antimicrobial peptide synthesis. Phenylalanine derivatives, including 4-hydroxybenzaldehyde, which increased over 430-fold (Log2 FC = 8.78), contributed to membrane-disruptive antibacterial effects. Mechanistically, A. niger hydrolyzes cellulose to release precursors, B. subtilis synthesizes antimicrobial peptides, and S. cerevisiae enhances metabolite solubility and excretion, collectively boosting antibacterial activity by 80%, suggesting a potent synergistic interaction among the triple microbiota. This cascade mechanism provides a scalable approach for valorizing approximately 55 million tons of traditional Chinese medicine (TCM) waste annually.","PeriodicalId":507249,"journal":{"name":"Fermentation","volume":"11 11","pages":"643-643"},"PeriodicalIF":0.0,"publicationDate":"2025-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147333440","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The culture medium composition was then sequentially optimized by single-factor experiments, a full factorial design, and an orthogonal design. Our results showed that the optimal incubation time was 30 h post inoculation, while initial pH had no effect on prodiginine production within the range of pH 6.0 to 8.0. By orthogonal design, the optimal medium was determined as follows: peptone 11 g/L, yeast extract 1 g/L, soybean oil 5 mL/L and MgCl2·6H2O 3 g/L in seawater. Verification experiments showed that prodiginine concentration under the optimized conditions reached 14.64 mg/L, representing 2.62 times the concentration obtained in basal Marine Broth 2216.

Given that highland barley spent grain (BSG) is a byproduct of the brewing process and is frequently considered waste, the efficient extraction of its β-glucan could promote high-value repurposing of BSG. In this study, 2.74% β-glucan (BSG-B) was extracted from Rhizopus oryzae (R. oryzae)-fermented BSG, which is lower than those from THB (THB-B: 4.62%) yet enabled value-added utilization of BSG. The molecular weight of BSG-B was 5.24 × 106 Da, which significantly increased by 124.89% compared to that of THB-B. Fourier-transform infrared (FT-IR) spectroscopy showed similar absorption peaks in BSG-B and THB-B, except for structural modifications in the β-glucan pyranose ring induced by the fermentation of R. oryzae. Scanning electron microscopy (SEM) and atomic force microscopy (AFM) indicated that BSG-B possesses a more compact structure and lower aggregation heights compared to THB-B. Moreover, BSG-B demonstrated superior antioxidant capacities to THB-B in NO/DPPH/ABTS/reducing power assays, and lower apparent viscosity and oil adsorption capacity, likely attributed to the fermentation of R. oryzae.

Through single-factor experiments and Box–Behnken response surface optimization, we demonstrated that mannitol supplementation combined with cellulase treatment of substrate significantly enhanced the yields of MPs. The optimal conditions (4.00% mannitol, cellulase hydrolysis at 60 °C for 2 h) achieved a maximum color value of 3538 U/g. Furthermore, comparative evaluation under different culture conditions, including only rice bran (RB), cellulase hydrolysis of rice bran (Cel), rice bran supplemented with mannitol (Man), mannitol supplementation combined with cellulase pretreatment of substrate (Opti), and only rice (Rice), confirmed the effectiveness of the optimized treatment. The color value of the Opti group was 27.95 times more than that of the RB group and reached 80.96% of the counterpart of the Rice group. The Opti group also significantly enhanced the yields of two orange pigments (Monascorubrin and Rubropunctatin), induced more sexual spore formation, and exhibited the maximum biomass and colony diameter among different groups. The hyphae of the Man and Opti groups were full, intact, and tubular. The citrinin content in the Opti group was under the limit standard of China.
