Through stepwise evaluation, we identified two best synthetic modules, RE-6 and RE-38, which enabled an industrial lysine-producing strain to maintain lysine titers and yields at pH 5.5 comparable to those observed in the parent strain at pH 6.8. Transcriptional analyses revealed that upregulation of key acid-resistance genes involved in protein quality control, reactive oxygen species scavenging and redox homeostasis contributed to the enhanced acid tolerance of the engineered strains.

Bioactive peptides (BAPs), including antimicrobial peptides, are emerging as an exciting new class of compounds with advantages over current drug modalities, especially small molecule drugs that are prone to resistance development. Here, we evaluated a bacteriophage P22 virus-like particle (VLP) system where BAPs are encapsulated as fusion proteins with the P22 scaffold protein (SP) within self-assembling protein cages in <i>Escherichia coli</i>. Representative peptides from three structurally distinct classes of BAPs were successfully encapsulated into P22 VLPs at high cargo to VLP coat protein (CP) ratios that corresponded to interactions between the compact electropositive structures of the SP-BAPs and electronegative regions on the inward facing surface of CP subunits. However, high loading densities did not correspond to improved SP-BAP yields. An unexpected finding of this study was that while encapsulation alleviated negative effects of SP-BAPs on <i>E. coli</i> growth, the P22 scaffold protein acted as a sufficient fusion partner for accumulating BAPs, and co-expression of the CP did not further improve SP-BAP yields. Nevertheless, encapsulation in VLPs provided a useful first step in the purification pipeline for producing both linear and cyclic recombinant (r)BAPs that were functionally equivalent to their synthetic counterparts. Further efforts to optimise expression ratios of CP to SP-BAP fusions will be required to realise the full potential of encapsulation for protecting expression hosts and maximising rBAP yields.</p>","PeriodicalId":209,"journal":{"name":"Microbial Biotechnology","volume":"18 6","pages":""},"PeriodicalIF":5.7,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/1751-7915.70158","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144197450","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, for these spores to exert their full beneficial effects, they must germinate. The specific germination signals in the rhizosphere, particularly those from plant root exudates, remain largely unknown. Here, we investigated the germination signals from different growth states of cucumber (<i>Cucumis sativus</i>) for spores of <i>Bacillus velezensis</i> SQR9 and <i>Bacillus subtilis</i> NCIB 3610. We identified the corresponding germination receptors and compared them biochemically between the <i>Bacillus</i> species. Larger plants better stimulated spore germination. Five amino acids—L-isoleucine, L-ornithine, L-valine, L-serine and β-alanine were—identified as spore germination signals. Combined application of a mixture of these amino acids with bacterial spores markedly enhanced the cucumber growth-promoting properties of <i>B. velezensis</i> SQR9. The germination receptor for these amino acids was GerA in both <i>Bacillus</i> species. Differences in spore germination efficiency between <i>B. subtilis</i> and <i>B. velezensis</i> may be attributable to variations in the GerA ligand-recognition sites. Expression of GerA from <i>B. subtilis</i> NCIB 3610 in <i>B. velezensis</i> SQR9 enhanced the spore germination rate of the latter. Our study highlights the pivotal role of amino acids in regulating spore germination of <i>Bacillus</i> and subsequent plant root colonisation, emphasising their potential to enhance the efficacy of <i>Bacillus</i>-based biofertilisers.

Human faecal microbiota transplantation (FMT) is often employed in murine models to investigate the role of human microbes in disease regulation, but methods for effective colonisation require refinement. This study aimed to assess the colonisation efficiency of human microbiota in a murine model using FMT with human faeces, focusing particularly on the impact of gut microbiota depletion via polyethylene glycol (PEG) and comparing oral-gastric gavage with enema administration routes. Our findings revealed that PEG-induced depletion enhanced human microbiome colonisation in mice. Oral-gastric gavage prolonged colonisation, while enema administration facilitated quicker resolution of dysbiosis, both inducing selective human microbial colonisation in a time-dependent manner. Notably, genera such as <i>Bacteroides</i>, <i>Blautia</i>, <i>Medicaternibacter</i> and <i>Bifidobacteria</i> were successfully colonised, whereas <i>Roseburia</i>, <i>Anaerostipes</i>, <i>Anaerobutyricum</i> and <i>Faecalibacterium</i> failed to establish in the murine gut post-FMT.

The virulence arsenal of UPEC includes factors, such as curli fimbriae, hemolysin, motility elements and metallophores. Moreover, UPEC can form biofilm-like communities and quiescent intracellular reservoirs within host tissues, contributing to recurrent and persistent infections. This study investigates the antibiofilm and antimicrobial activities of two halogen-substituted aniline derivatives, 4-bromo-3-chloroaniline (4B3CA) and 3,5-dibromoaniline (3,5-DBA), against UPEC. The compounds demonstrated minimum inhibitory concentrations (MICs) of 200 μg/mL for 4B3CA and 100 μg/mL for 3,5-DBA, with both exhibiting a biofilm inhibition IC50 value of 10 μg/mL. Additionally, these derivatives showed antibiofilm activity against ESKAPE pathogens. Treatment with 4B3CA and 3,5-DBA led to significant downregulation of UPEC virulence- and biofilm-related genes, including those involved in curli production, fimbrial adhesion, motility, iron acquisition, quiescent colony formation, and stress response. Interestingly, a mild upregulation of <i>hlyA</i>, <i>csrA</i> and <i>uvrY</i> was noted, alongside a marked downregulation of the adenylate cyclase genes <i>cyaA</i> and <i>crp</i>. These findings suggest that inhibition of adenylate cyclase activity may be a primary mode of action, leading to both antimicrobial and antibiofilm effects. The presence of halogen atoms in these compounds appears to enhance their binding affinity to adenylate cyclase through stabilising halogen bond interactions. Furthermore, 3D-QSAR analysis indicates that electrostatic favourability at the third and fourth positions of the aniline ring is critical for bioactivity. Finally, in silico ADMET profiling and cytotoxicity assessments using <i>Caenorhabditis elegans</i> suggest that these aniline derivatives hold promise as therapeutic candidates, warranting further investigation.</p>","PeriodicalId":209,"journal":{"name":"Microbial Biotechnology","volume":"18 5","pages":""},"PeriodicalIF":5.7,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/1751-7915.70165","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144135693","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biofertilizers promote crop growth by providing or activating essential nutrients, suppressing plant pathogens, improving soil health, and increasing resilience to abiotic stresses. The growing adoption of biofertilizers in China is reflected in the registration of more than 10,000 products, an annual production exceeding 35 million tons, and a market value of over US$5.5 billion, indicating a significant shift towards sustainable agricultural practices.
