Among the two populations, HHA exhibited higher total phenolic and flavonoid contents, which were associated with significantly stronger antioxidant activities across multiple assays. Furthermore, HHA showed more pronounced α-glucosidase inhibitory activity compared to HHB, whereas α-amylase and cholinesterase inhibition remained weak to moderate and population-dependent. LC–MS/MS analysis identified neochlorogenic acid, hyperoside, quercitrin, catechin, and procyanidin B2 as the principal metabolites driving these activities. Both extracts exhibited complex and phenolic-rich chemical profiles; however, HHA consistently contained higher levels of major caffeoylquinic acids, flavonoids, and flavan-3-ols, which was reflected in superior antioxidant performance (2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), ferric reducing antioxidant power (FRAP), and cupric reducing antioxidant capacity (CUPRAC)), stronger tyrosinase and α-glucosidase inhibition, and enhanced antimicrobial activity—particularly against Gram-positive bacteria—compared to HHB.

This antibody pair not only exhibits excellent binding affinity for native LF but also possesses processing-dependent recognition ability for heat-treated LF. While mild denaturation at 75 °C reduces its recognition efficiency, it promotes the formation of stable lactose-LF complexes, thereby preserving conformation-dependent antigenicity. In contrast, combined high-temperature and pressure processing overrides the protective effect of lactose, rendering sELISA detection ineffective. Based on experimental and molecular docking results, the positive effect of lactose on LF antigenicity during thermal processing provides key support for distinguishing between pasteurization and ultra-high temperature (UHT) processing.

This has constrained access to the vast catalytic potential encoded within microbial communities inhabiting extreme, diverse, and underexplored ecosystems. Metagenomics has emerged as a transformative approach to overcome these limitations. This methodology rapidly unlocks access to novel enzyme families, offering orders-of-magnitude greater diversity than traditional screening. By integrating sequence-driven and function-driven strategies, metagenomics enables the discovery, characterization, and engineering of next-generation biocatalysts for fermentation-based industries. Hydrolases remain the most extensively studied, with applications in starch processing, dairy fermentation, and lignocellulosic bioconversion. Oxidoreductases, including laccases and alcohol dehydrogenases, contribute to bioethanol production, detoxification, and flavor development, while transferases, lyases, and multifunctional enzymes offer opportunities for efficient synthesis of value-added metabolites and streamlined multi-step processes. These discoveries not only improve fermentation efficiency but also reduce energy inputs, waste generation, and production costs. Advances in bioinformatics pipelines, coupled with machine learning (ML) and artificial intelligence (AI), now facilitate precise gene prediction, functional annotation, and enzyme design. Despite challenges in heterologous expression due to codon usage, folding inefficiencies, and post-translational requirements, metagenomics holds immense promise. This review synthesizes current progress in enzyme mining and highlights how integrating metagenomics with synthetic biology can drive precision fermentation. This review highlights how metagenomics delivers a significant quantitative advantage, often yielding enzymes with improved stability and efficiency, which fundamentally reduce bioprocess costs and enhance industrial scalability.</div></div>","PeriodicalId":12409,"journal":{"name":"Food Bioscience","volume":"77 ","pages":"Article 108391"},"PeriodicalIF":5.9,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147399457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results showed that compared with the model group, mice in high-dose prophylaxis group (PH6 group) exhibited lower clinical scores for allergic symptoms and decreased levels of OVA-specific IgE (OVA-sIgE), OVA-sIgG1, histamine, mouse mast cell protease (mMCP) 1, and interleukin (IL) 4 by 52.00%, 54.43%, 18.82%, 6.48%, and 29.04%, respectively.

In addition, oral administration of <em>L. paracasei</em> BHP06 maintained immune organ homeostasis in allergic mice, decreased gene expression of IL-4, TNF-α, and GATA-3 in the spleen, increased gene expression of IL-10, T-bet, Foxp3, and TGF-β, and modulated the expression of genes associated with the TLR4/NF-κB signaling pathway. 16S rDNA sequencing analysis revealed that the intake of <em>L. paracasei</em> BHP06 enhanced the ratio of <em>Firmicutes</em>/<em>Bacteroidota</em> in the gut, leading to significant alterations in the diversity. In summary, oral administration of <em>L. paracasei</em> BHP06 exhibited multiple beneficial effects in alleviating FA by regulating immune balance, intestinal inflammation, TLR4/NF-κB signaling pathway, and intestinal flora.

Within a multi-omics framework, we identified exploratory behavior as the most stable anxiety-related trait across developmental stages. High-anxiety adults exhibited a distinct neuroendocrine signature—elevated crustacean hyperglycemic hormone (CHH) and hemolymph lactate alongside suppressed neuropeptide F (NPF). Conversely, low-anxiety crabs possessed superior flesh quality, characterized by significantly higher umami substances and lower safety- and oxidative DNA damage-related indicators, revealing a clear quality-safety gradient linked to anxiety. Structural equation modeling supported the associations of behavioral phenotype with flesh quality and safety. We thus established the first integrative framework from anxiety-like behavior to flesh quality in crustaceans and demonstrated the feasibility of early-life behavioral screening for non-invasive quality prediction and genetic selection.
