However, most strains currently used are derived from non-aquatic sources, which may limit their colonization and efficacy in fish. In this study, a novel strain, C. butyricum LZK-08, was isolated from the intestine of grass carp. The strain was identified based on morphological features, 16S rRNA sequencing, and whole-genome analysis. Its probiotic properties were assessed through comprehensive in vitro assays and in vivo trials in largemouth bass. LZK-08 exhibited strong acid (pH 4.0), bile salt (0.3%), and heat (up to 80 °C) tolerance, along with high auto-aggregation (92.3%) and notable surface hydrophobicity. It produced digestive enzymes (amylase, protease, lipase) and short-chain fatty acids, particularly butyrate (523.32 μg/mL). Genomic analysis revealed a 4.71 Mb genome composed of a circular chromosome and plasmid, encoding 4,207 protein-coding genes. Key genes were enriched in carbohydrate and amino acid metabolism, stress response, and adhesion. Feeding trials in largemouth bass showed that dietary supplementation with LZK-08 significantly improved growth parameters, reduced feed conversion ratio, enhanced intestinal antioxidant enzyme and digestive enzyme activities. Histological analysis revealed improved intestinal morphology, including increased villus height and muscle thickness. 16S rRNA sequencing further showed that LZK-08 modulated gut microbiota by enriching beneficial taxa such as Lactobacillus and reducing potentially unfavorable Romboutsia. These findings indicate that C. butyricum LZK-08 is a physiologically robust, and genomically safe probiotic with strong functional attributes, demonstrating high potential for use in sustainable aquaculture.</p>","PeriodicalId":20506,"journal":{"name":"Probiotics and Antimicrobial Proteins","volume":" ","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145001308","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the inconsistent effectiveness of traditional anticancer therapies, there is an increasing need for novel drug-free cancer therapy that enhances the efficacy of current treatments with minimum side effects. CRC is linked to microbiome modifications, a phenomenon termed dysbiosis, which entails the reduction and/or augmentation of certain gut bacteria and their metabolites. Administration of next-generation probiotics (NGP) may serve as an effective and accessible cancer treatment by regulating gut microbiota composition. The review provides a focused analysis of NGPs in CRC, highlighting their preventive and therapeutic roles, modulation of gut microbiota and signaling pathways, and current translational progress. Restoration of intestinal microbiota in cancer patients may promote anti-inflammatory, anticarcinogenic, immunomodulatory, and other physiologically significant pathways that exhibit high selectivity for tumor cells. The potential advantages of NGP include the modulation of intestinal microbial community and functionality, in addition to influencing the host's inflammatory response. NGPs that help maintain gut balance include Bacteroides fragilis, Akkermansia muciniphila, Propionibacterium freudenreichii, and specific strains of Clostridium spp. This review emphasizes their applicability in CRC prevention, with promising preclinical evidence from animal models. Recent evidence suggests that NGP may provide novel therapeutic approaches for CRC by facilitating physiological processes via the generation of immuno-modulatory metabolites that counteract CRC. Despite the observed positive outcomes in preclinical studies, more research concentrating on targeted strain, safe use, and dosage specificity is necessary to confirm the effectiveness and safety profile of NGP in the treatment of CRC.</p>","PeriodicalId":20506,"journal":{"name":"Probiotics and Antimicrobial Proteins","volume":" ","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144966222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The native bacteriocin operon typically includes accessory proteins that facilitate disulphide bond formation, but this gene is absent in the enterocin A operon. In this study, the recombinant expression of a codon-optimised gene for enterocin A in S. cerevisiae, was compared to that for a codon-optimised plantaricin 423 and mundticin ST4SA, previously successfully expressed in S. cerevisiae. Shake flasks delivered more than twofold higher peptide EntA_Opt levels than PlaX_Opt and MunX_Opt, with even higher EntA_Opt expression levels in batch fermentations.

This study introduces Lactiplantibacillus plantarum (L. plantarum) QL-19, a novel probiotic strain isolated from traditional Hunan pickles and characterized via whole-genome sequencing and in vitro functional assays. The 3,396,702 genome contains 3236 predicted coding sequences, including genes associated with stress tolerance, adhesion, and cholesterol metabolism (cbh, cfa, and hydroxymethylglutaryl-CoA synthase). Genomic analysis further revealed biosynthetic gene clusters encoding antimicrobial and antioxidant compounds, emphasizing its functional versatility. A comprehensive safety assessment confirmed that QL-19 is non-pathogenic and non-hemolytic, meeting probiotic safety standards. In HepG2 cell-based experiments, L. plantarum QL-19 reduced intracellular total cholesterol levels. RT-qPCR and Western blotting were employed to evaluate the expression of genes and proteins involved in cholesterol metabolism. The results demonstrated that QL-19 enhanced cholesterol metabolism by upregulating the expression of SREBP2, LDLR, and CYP7A1, while downregulating NPC1L1 and HMGCR. The results suggest that QL-19 facilitates cholesterol metabolism through multiple pathways.
