This study presents a comprehensive analysis of the probiotic potential of strain LMG S-24828, originally isolated from healthy human feces. The genomic analysis confirmed the strain's taxonomic placement within the species H. coagulans and revealed no extrachromosomal plasmid DNA, suggesting genetic stability. Safety assessments demonstrated that LMG S-24828 does not produce D-lactate, deconjugate bile salts, or exhibit hemolytic activity, and it lacks transmissible antibiotic resistances. Phenotypic tests showed the strain's metabolic versatility, including its ability to hydrolyze complex carbohydrates and adhere to intestinal epithelial cells. Moreover, LMG S-24828 exhibited robust survival and germination during in vitro and in vivo gastrointestinal simulations, with evidence of significant spore germination in the human gut. These findings suggest that H. coagulans LMG S-24828 possesses several advantageous traits for probiotic applications, warranting further clinical evaluation to confirm its health benefits.</p>","PeriodicalId":20506,"journal":{"name":"Probiotics and Antimicrobial Proteins","volume":" ","pages":""},"PeriodicalIF":4.4,"publicationDate":"2024-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142473167","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}

In this sense, encapsulation using 3D printing emerges to protect probiotic microorganisms and ensure that they reach the intestine viable and carry out the expected beneficial action. Thus, this review evaluates the current advancements in 3D printing to encapsulate and develop novel probiotic foods. Research has shown that 3D printing effectively encapsulates probiotic microorganisms, preserving their viability throughout the gastrointestinal tract. Studies have proven the effectiveness of 3D printing encapsulation in protecting probiotics during processing, storage, and digestion. Innovative formulations for 3D bioprinted products with probiotics, such as food structures based on cereals, mashed potatoes, and cream, have been developed. Producing products with shelf life and combining applications of phytochemicals and probiotics aims to improve personalized nutrition, textural characteristics, and sensory attributes of the foods produced by this emerging approach.

In results, the strain showed a single circular chromosome (3,145,837 bp) with a GC content of 56.73%, a higher number of accessory and unique genes, an open pan-genome, and the absence of mobile and insertion elements, plasmids, virulence, and transmissible antibiotic resistance genes.

The γ-hemolytic nature, usual antibiotic susceptibility profile, and negative results for mucin and gelatin degradation ensure the safety of the strain.

However, the use of synthetic antioxidants in studies has raised concerns about their potential link to liver disease and cancer. The findings show that postbiotics have the potential to act as a suitable alternative to chemical antioxidants in the food and pharmaceutical sectors. Postbiotics are bioactive compounds generated by probiotic bacteria as they ferment prebiotic fibers in the gut. These compounds can also be produced from a variety of substrates, including non-prebiotic carbohydrates such as starches and sugars, as well as proteins and organic acids, all of which probiotics utilize during the fermentation process. These are known for their antioxidant, antibacterial, anti-inflammatory, and anti-cancer properties that help improve human health. Various methodologies have been suggested to assess the antioxidant characteristics of postbiotics. While there are several techniques to evaluate the antioxidant properties of foods and their bioactive compounds, the absence of a convenient and uncomplicated method is remarkable. However, cell-based assays have become increasingly important as an intermediate method that bridges the gap between chemical experiments and in vivo research due to the limitations of in vitro and in vivo assays. This review highlights the necessity of transitioning towards more biologically relevant cell-based assays to effectively evaluate the antioxidant activity of postbiotics. These experiments are crucial for assessing the biological efficacy of dietary antioxidants.

The mice were split up into various treatment groups, including a control group, an aflatoxin-treated group, and groups treated with the aflatoxin-contaminated diet along with Lactobacillus strains. Various parameters, including liver enzymes, blood parameters, malondialdehyde (MDA) levels, morphometric analysis of ileum, and gene expression, were analyzed to assess the effectiveness of the Lactobacillus strains in mitigating aflatoxins toxicity. Results showed that mice in the aflatoxin-treated group had increased MDA levels, indicating oxidative stress.

The morphometric analysis of ileum tissue demonstrated that the Lactobacillus-treated group exhibited improved structural integrity compared to the aflatoxin-treated group. Additionally, gene expression analysis revealed that the Lactobacillus treatment attenuated the downregulation of SOD gene expression and mitigated the upregulation of iNOS gene expression induced by aflatoxins. These findings suggest that Lactobacillus strains have the potential to reduce aflatoxin-induced toxicity by alleviating oxidative stress, preserving intestinal tissue integrity, and modulating gene expression associated with antioxidant defense and inflammation.
