Microbial biofilms are crucial for primary production and decomposition in Arctic streams and support higher trophic levels. However, comprehensive studies across Arctic regions, and in particular within Greenland, are scarce. This study analysed total biomass, autotrophic biomass (chlorophyll a), and the general structure of major autotrophic groups in stream epilithic biofilms across Greenland's subarctic, Low Arctic, and High Arctic regions. Our aim was to identify primary environmental drivers of biofilm across these climate regions. We observed large environmental variation differences in biofilm chlorophyll a concentrations and total biomass across the regions. Cyanobacteria, diatoms, and green algae were present in all regions, with cyanobacteria dominating High Arctic streams. Phosphate and water temperature primarily drove autotrophic biofilm abundance measured as chlorophyll a concentration, while catchment slope and nitrate concentrations influenced total biofilm biomass, with relationships varying by region. Our results suggest increased biofilm accumulation in Greenland streams under projected climate warming, which likely will alter trophic food webs and biogeochemical cycling, with region-specific responses expected.","PeriodicalId":163,"journal":{"name":"Environmental Microbiology Reports","volume":"17 2","pages":""},"PeriodicalIF":3.6,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/1758-2229.70074","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143602831","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}

The phenyl acids phenyl-acetic-(PAA), phenyl-propionic-(PPA), and phenyl-butyric acid (PBA) are such intermediates suspected to negatively affect the microbial community, resulting in a decreased biogas yield. In the present study, the impact of PAA, PPA, and PBA on the metabolism of CO2 reducing methanogens was investigated. The mesophilically incubated Methanococcus vannielii and Methanospirillum hungatei showed a higher sensitivity than the thermophilic Methanoculleus thermophilus, Methanothermobacter thermoautotrophicus, and Methanothermobacter wolfei. A concentration of 35 mM PPA and 35 mM PBA inhibited methanogenesis and the growth of M. hungatei almost completely. PBA had the greatest detrimental impact on methanogens across all tested phenyl acids, followed by PPA and PAA. However, in further investigations, it has to be clarified if and how other microorganisms involved in AD are impacted by phenyl acids. A more detailed knowledge will help to better understand disturbances due to phenyl acid emergence caused by the degradation of lignocellulose- and protein-rich substrates, to ensure a stable AD process even at high loads of these substrates.","PeriodicalId":163,"journal":{"name":"Environmental Microbiology Reports","volume":"17 2","pages":""},"PeriodicalIF":3.6,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/1758-2229.70082","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143602553","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}

A dual approach, utilising PacBio long-reads and Illumina short-reads, was employed to enhance the accuracy of taxonomic assignment and compare sequencing methods. The diversity of Planctomycetota increased below the deep chlorophyll maximum level (175–200 m) and in the mesopelagic layer (500 m), with beta-diversity clustering distinctly separating samples according to different depths, resulting in pronounced vertical stratification. This community structure mirrors nutrient availability, as Planctomycetota favour depths between 175 and 200 m, where high nitrate levels are present. More Planctomycetota amplicon sequence variants (ASVs) were identified with PacBio than with Illumina, improving detection of these bacteria. Phylogenetic analyses performed after manual curation of ASVs led to the discovery of several unknown genera of Planctomycetota, indicating that substantial diversity within this group remains to be discovered and studied in remote oligotrophic oceans.","PeriodicalId":163,"journal":{"name":"Environmental Microbiology Reports","volume":"17 1","pages":""},"PeriodicalIF":3.6,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/1758-2229.70063","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143447210","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}

Transmission electron microscopy and energy-dispersive X-ray spectroscopy observations demonstrated magnetite cuboctahedral, prismatic, and anisotropic magnetosomes. PCA ordination demonstrated a more significant influence of depth, ORP (oxidation–reduction potential), and transparency in sampled data from the river main channel (MC). Non-metric multidimensional scaling (NMDS) ordination and correlation analysis demonstrated a difference between MTB populations inhabiting MC and lakes and affluent (LA). NGS and bioinformatic analysis revealed higher richness and diversity among magnetotactic cocci and the majority phylogenetic assignment of MTB affiliated to Pseudomonadota phylum.

Nutrient enrichment positively correlates with microbial aggregation. This correlation is largely attributed to the overgrowth of microalgae and the overproduction of agglomerating exopolysaccharides. However, recent studies highlight the significant contribution of bacterial exopolysaccharides to algal-bacterial aggregation. Here, using controlled laboratory experiments and environmental metatranscriptomic analysis, we investigate the impact of nutrient enrichment on bacterial exopolysaccharides production, while bacteria are in the context of their algal hosts. Our findings demonstrate a marked increase in bacterial exopolysaccharides production in response to a relative increase of inorganic phosphorus and nitrogen levels, both in the lab and in the environment. These results highlight the interplay between nutrient regimes, bacterial physiology and microbial aggregation in marine ecosystems and emphasise gaps in our understanding regarding the bacterial role in environmental processes that involve microbial aggregation.","PeriodicalId":163,"journal":{"name":"Environmental Microbiology Reports","volume":"17 1","pages":""},"PeriodicalIF":3.6,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/1758-2229.70071","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143248488","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 elucidated the microbiomes of 32 non-axenic Coleofasciculus isolates using PacBio-based amplicon sequencing of the complete 16S rRNA gene and the internally transcribed spacer (16S-ITS). The length of authentic amplicon sequence variants (ASVs) ranged from 1827 to 3044 nucleotides (median: 2267 nt). The results, which were complemented by metagenome analyses and cultivation approaches, revealed the presence of more than 70 associated heterotrophs in the culture of Coleofasciculus sp. WW12. The great bacterial diversity in the cyanosphere is dominated by Pseudomonadota (59%) and Bacteroidota (23%). Allelic ribosomal operon variants were detected in 18 Coleofasciculus strains and our analyses proposed the presence of at least four different species. A comparative analysis of cyanobacterial microbiomes documented complementary advantages of amplicon sequencing versus metagenomics with an individual strength of the 16S-ITS approach in terms of (i) ribosomal target sequence quality, (ii) contaminant detection and (iii) identification of rare bacteria. The characterisation of the Coleofasciculus microbiome showed that long-read amplicon sequencing of the 16S-ITS region is the method of choice for rapid profiling of non-axenic cyanobacteria.

Three maternally inherited symbionts are recognised: Wolbachia (an obligate partner), Symbiopectobacterium purcellii strain SyClec, and Candidatus Tisiphia sp. (facultative symbionts typically present in some but not all individuals). Past work had examined the presence of these heritable microbes from established laboratory lines, but not from broader field samples. We therefore deployed targeted endpoint PCR assays to determine the symbiont infection status for 50 bedbugs collected from 10 districts of Paris during the 2023 outbreak. All three symbionts were found to be broadly present across Cimex lectularius samples, with the Symbiopectobacterium-Candidatus Tisiphia-Wolbachia triple infection most commonly observed. A minority of individuals lacked either one or both facultative symbionts. Five mtDNA haplotypes were observed across the COI barcode region, and triple infections were found in all mtDNA haplotypes, indicating that symbiont infection is not a recent invasion event. We conclude that the Parisian bedbug outbreak was one in which the host's secondary symbionts were present at high-frequency coinfections, and facultative symbionts are an important but uncharacterised component of bedbug populations.","PeriodicalId":163,"journal":{"name":"Environmental Microbiology Reports","volume":"17 1","pages":""},"PeriodicalIF":3.6,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11779572/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143062174","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}

The microbial complexes within SR-affected grapes exhibit variability among different bioclimates and seasons, with certain microorganisms predominating under specific conditions. This study examined the influence of environmental conditions on the microbiome composition associated with SR-affected grape bunches, utilising data from 41 locations across three distinct Italian bioclimates. We selected nine yeast and two bacterial species frequently isolated from sour-rotted grapes for analysis. The growth responses of these microorganisms to temperature were assessed by categorising them into four ecophysiological clusters. Furthermore, we analysed the distribution of these microorganisms and their respective ecophysiological clusters across the three bioclimates.
