This study analysed four publicly available anaerobic digester shotgun metagenomic datasets (M2, M3, M12 and M17) retrieved from the NCBI Sequence Read Archive to characterise microbial functions, resistance-associated annotations and antibiotic target loci. The datasets were generated using Illumina HiSeq 2000 sequencing and analysed through quality assessment, assembly, functional annotation and resistome profiling. A total of 1082 resistance-associated annotations were identified, with the highest abundance detected in M2 (348), followed by M12 (276), M17 (259) and M3 (205). Detected annotations were associated with diverse antimicrobial categories, including aminoglycosides, quinolones, beta-lactams, tetracyclines, glycopeptides, macrolides and sulfonamides. Several frequently detected loci, including rpoB, rpoC, gyrA, gyrB, EF-Tu, EF-G, Ddl and KasA, were interpreted as antibiotic target or housekeeping loci rather than confirmed acquired resistance genes. Exploratory co-abundance analysis identified strong associations among functionally linked loci, including rpoB-rpoC and gyrA-gyrB, likely reflecting shared genomic occurrence or functional relationships. These findings highlight the resistome potential of anaerobic digesters while emphasising the need for host-resolved metagenomics, mobile genetic element analysis and mutation-level characterisation to clarify environmental AMR risks.","PeriodicalId":163,"journal":{"name":"Environmental Microbiology Reports","volume":"18 5","pages":""},"PeriodicalIF":3.1,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13628450/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149101620","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We assessed alpha- and beta-diversity, distance decay relationships, immigration rates and community assembly processes, variance partitioning between space and environment and putative prokaryotic and fungal functions from the upper 20 cm of soil during summer 2023. Despite uniform management practices, orchards showed a huge variability in alpha diversity, with single orchards having only a small part of total diversity. Protists showed the lowest mean beta-diversity, followed by prokaryotes and fungi. Although immigration rates were low across all organismal groups-reflecting the low number of taxa co-occurring across all orchards-prokaryotes and protists still displayed relatively higher rates than fungi, in support of the size-plasticity hypothesis. Community assembly was governed primarily by stochastic processes, even though deterministic processes were also important. Turnover dominated community composition for all organismal groups. Putative functions of prokaryotes pertained mainly to carbon and nitrogen cycling.

In this study, we investigated the structure of microbial communities and their ecological profiles in daycare and home dust in the post-COVID-19 era. Microbial communities in household dust remain more heterogeneous, with a higher prevalence of human-associated species, than daycare samples. Full-length 16S rRNA gene sequencing enabled species-level taxonomic resolution, yet approximately 40% of amplicon sequence variants remained unclassified, underscoring the vast, novel microbial diversity within our indoor environments encountered in everyday life. AI-assisted ecological profiling revealed a higher burden of pathogens and opportunistic pathogens in home environments than in daycares. Interestingly, the presence of pets had limited influence on microbial diversity in household dust. Finally, several species with known probiotic properties and immunostimulatory potential were present in both environments, reinforcing the notion that microbial exposure during the critical window of early childhood may confer protection against various non-communicable diseases including asthma, childhood leukaemia and other cancers.","PeriodicalId":163,"journal":{"name":"Environmental Microbiology Reports","volume":"18 5","pages":"e70433"},"PeriodicalIF":3.1,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13668400/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149178294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Seven of the 22 bacterial isolates showed discrete zones of orange colour, indicating siderophore production.

Here, we characterize the volatilome of 16 heterotrophic bacterial strains isolated from Baltic Sea surface water, spanning Alphaproteobacteria, Gammaproteobacteria, Betaproteobacteria, Bacteroidota and Actinomycetes. Headspace BVOCs were quantified under standardized growth conditions using Proton Transfer Reaction Time-of-Flight Mass Spectrometry (PTR-TOF-MS). A broadly overlapping bacterial volatilome was identified, with compound composition and proportional abundance similar across many strains, irrespective of phylogeny. Namely, most strains shared a set of core compounds with a subset of strain-specific, low abundance compounds. Acetone accounted for more than 50% of the emissions in most volatilomes. The remaining fraction of emissions was primarily comprised of other low-molecular-weight oxygenated compounds. Interestingly, two strains demonstrated strain-specific emission patterns, significantly diverging from the group in their emission rate and compound composition. Together, these findings suggest that marine heterotrophic bacteria may contribute a broadly conserved collection of BVOCs to the ocean-atmosphere interface, highlighting their role as a widespread source of trace gases in marine ecosystems.","PeriodicalId":163,"journal":{"name":"Environmental Microbiology Reports","volume":"18 5","pages":"e70439"},"PeriodicalIF":3.1,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13677163/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149219788","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, this hypothesis and its mechanism remain surprisingly underexplored. In this study, we conducted a 10-year nitrogen deposition experiment in the Eurasian steppe, manipulating nine intensities under two management strategies (fencing or mowing). As the intensity increased from 0–20 to 50 g N m−2 yr−1, the succession rates of both plant and soil microbial communities first increased but then decreased, implying that high intensities of N deposition exceed the capacity of community adaptation. In addition, both the succession rate of the deterministic component of community compositional variation and the succession rate of soil physicochemical characteristics increased and then decreased with increasing N intensity. They were positively correlated, demonstrating that adaptation is primarily driven by deterministic ecological processes. Meanwhile, mowing promoted the plant community's adaptation, while fencing promoted adaptation of the microbial community, both by restraining stochastic processes. Overall, to enable biological communities to adapt compositionally to environmental changes, we should aim to limit the intensity of changes below certain thresholds, and implement reasonable strategies, whether deterministic (e.g., restoring soil physicochemical conditions) or stochastic (e.g., adding seeds of adaptive species).","PeriodicalId":163,"journal":{"name":"Environmental Microbiology Reports","volume":"18 5","pages":""},"PeriodicalIF":3.1,"publicationDate":"2026-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13626865/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149101642","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study systematically elucidates the divergent effects of penicillin–streptomycin exposure and temperature gradients on Saccharina japonica gametophytes and their epiphytic microbiota. Antibiotic treatment significantly reduced Proteobacteria from 93.02% to 49.70% and increased Bacteroidetes from 6.98% to 49.20%, replacing beneficial Sulfitobacter and Colwellia with opportunistic Kordia and Klebsiella, indicating severe dysbiosis driven by the creation of unoccupied ecological niches. In contrast, temperature variation did not alter dominant phyla: Proteobacteria remained predominant, but Vibrio peaked at 15°C (44.11%) alongside the maximal gametophyte specific growth rate of 5.21% per day, concurrently elevating pathogenic loads of Vibrio and Pseudomonas. These findings reveal that antibiotics disrupt core community architecture, whereas temperature modulates metabolic rates within stable taxonomic frameworks. Consequently, we propose a stratified preservation strategy: short-term seedling cultivation at 15°C requires stringent antimicrobial measures to mitigate disease risk, while lower temperatures are preferable for long-term germplasm storage to minimize contamination potential.

However, the bioprocess remains challenging due to its complex microbial ecology, dynamic biochemical pathways and sensitivity to perturbations. Over the past decade, using meta-omics like metataxonomics, metagenomics, metatranscriptomics, metaproteomics and metabolomics to diagnose its functioning has become necessary and common. However, a single meta-omics method can only provide limited biological understanding of the bioprocess. This led to the use of multi-meta-omics analyses in tandem; however, most studies still examine and interpret each meta-omics separately, limiting their ability to uncover functional interactions across molecular levels. Currently, the frontier is integrated meta-omics, where multi-meta-omics and process data are systematically combined into a single and interpretable system to unlock mechanistic understanding, diagnostic and predictive control of AD. This review critically examines specific application of meta-omics in AD, discussing their strengths, limitations and distinct position in integrated meta-omics approach. Importantly, it explores the computational frameworks, methodologies and challenges of integrated meta-omics. Discovering diagnostic biomarkers with high predictive power and transferability across AD systems through cross-omics validation is highlighted.
