Complex mechanisms underlying growth-promotion by the gut microbiota have been described. In particular, strains of the same bacterial species within different genera exhibit strain-specific growth promotion. In a previous study, we used artificial selection on a poorly growth-promoting strain of Lactiplantibacillus plantarum (NIZO2877) and isolated evolved strains with enhanced growth-promoting capabilities in insects. However, it remains unclear to what extent existing growth-promoting strains can further optimise their benefits and whether these effects persist in well-fed mammals. Here, we experimentally evolved a Drosophila growth-promoting strain of L. plantarum (WJL) under conditions of nutrient deprivation. This strain had not undergone any prior evolutionary adaptation. Our aim was to maximize its growth-promoting benefits while evaluating the translation of this phenotype in different animal models. After artificial selection across ten Drosophila generations, we identified an evolved strain (L. plantarum IGFL1) that significantly improved Drosophila juvenile growth compared to the ancestral strain. Administration of IGFL1 to conventional C57Bl/6j male mice under both nutrient deprivation and normal dietary conditions significantly increased body length and weight growth rates compared to placebo-fed animals. These effects were comparable to those of the ancestral strain, suggesting a context-dependent phenotype. Genome sequencing of IGFL1 revealed the presence of four mutations that may be related to more effective utilization of nutrients. Our results demonstrate the high adaptive potential of L. plantarum, although functional improvements in promoting animal growth are strictly context-dependent. Despite this specificity in adaptation, both strains (the ancestral WJL and the evolved IGFL1) show transferable potential in terms of animal growth promotion, as they are both highly beneficial in flies and mice. These results pave the way for testing these strains to enhance the growth performance of agricultural target species.</p>","PeriodicalId":8834,"journal":{"name":"Beneficial microbes","volume":" ","pages":"1-11"},"PeriodicalIF":3.0,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143968113","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, growing evidence has suggested that a specific gut microbiome is associated with the pathophysiology of PD through the microbiota-gut-brain axis. We previously discovered that Proteus mirabilis induced motor impairment and brain dopaminergic neurodegeneration in normal mice. In this context, exploring beneficial microbe would be reasonable strategy to treat PD fundamentally. With that the current study aimed to evaluate whether Lactobacillus taiwanensis BCRC17755 (BCRC17755) could ameliorate PD pathologies induced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) and P. mirabilis in mice. To demonstrate this, we measured motor function by performing pole test and the rotarod test and conducted histological analysis to assess the changes of factors in both brain and the gut. As a result, BCRC17755 decreased faecal abundance of P. mirabilis, which was higher in both the MPTP and P. mirabilis-treated mice. Additionally, BCRC17755 improved the motor deficits and alleviated damage to nigrostriatal dopaminergic neurons observed in both MPTP and P. mirabilis-induced PD mice. Furthermore, BCRC17755 mitigated microglial hyperactivation triggered by MPTP and P. mirabilis in the substantia nigra pars compacta and striatum of mice. Similarly, the release of inflammatory cytokines, including interleukin-1 beta and tumor necrosis factor alpha, was suppressed following the administration of BCRC17755 in the colon.

In this study, a mechanistic understanding of fibre responses across health conditions was performed through in vitro faecal fermentations with various dietary fibres and faecal microbial communities from healthy individuals (HC) as well as Crohn's disease (CD), ulcerative colitis (UC), and Parkinson's disease (PD).

All tested dietary fibres increased short chain fatty acid production upon fermentation, with variations based on both, disease state and fibre type. The magnitude of shifts in microbial community structure resulting from in vitro fermentation varied by condition; for example, samples from individuals with UC responded weakly to fibre fermentation, while those from individuals with PD underwent dramatic changes. Still, each health condition had distinct fibre types that were more effective in shifting the community structure and increasing SCFAs.

Given the potential for these compounds in clinical settings, this study aims to provide a comprehensive review of the antivirulence activities of probiotics, with particular focus on lactic acid bacteria.

The addition of 2-bromoethanesulfonate inhibited methane production in the ME incubations, accompanied with a lower relative abundance of methanogens when pectin was used as substrate. However, altering methanogenesis did not significantly change overall microbiota composition and short-chain fat acid production in MEs and NMEs.

In this study gut microbiota profile of 30 obese and 23 lean Lebanese individuals was performed via DNA isolation and sequencing of the V3-V4 region of the 16S rRNA of faecal samples. The abundance of the phylum Verrucomicrobiota was higher in lean subjects and there was no significant difference in the Bacillota/ Bacteroidota ratio between the obese and lean groups. The evenness and Shannon alpha diversity indices were significantly higher in the lean group than in the obese group ( q = 0.012 and q = 0.030, respectively). Beta diversity was higher in the obese group based for unweighted uniFrac distance variability ( q = 0.047). Lachnoclostridium was the only genus that was higher in obese ( q = 0.013) and it is linked to diet induced obesity, while the abundance of the genera Peptococcus, Ruminococcus_2, Lachnospiraceae UCG-001, Ruminiclostridium 6, the uncharacterised taxon within Coriobacteriaceae, Ruminococcaceae UCG-005, Ruminococcaceae UCG-010 and Oxalobacter, were significantly higher in lean subjects. These bacterial species that were higher in lean people, possess anti-inflammatory properties through the production of short chain fatty acids and are linked with lower body mass index, promote satiety and weight loss and may play a role in the protection against obesity and type 2 diabetes. Further research to generate a clear understanding of the interaction of the gut microbiota and health is needed.</p>","PeriodicalId":8834,"journal":{"name":"Beneficial microbes","volume":" ","pages":"1-17"},"PeriodicalIF":3.0,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143456821","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
