Abstract Terrestrial geothermal springs are physicochemically diverse and host abundant populations of Archaea. However, the diversity, functionality, geological influences these Archaea not well understood. Here we explore genomic diversity in 152 metagenomes from 48 Tengchong, China, collected 2016 to 2021. Our dataset is comprised 2949 archaeal metagenome-assembled genomes spanning 12 phyla 392 newly identified species, which increases known species by ~48.6%. The structures potential functions communities strongly influenced temperature pH, with high-temperature acidic alkaline favoring abundance over Bacteria. Genome-resolved metagenomics metatranscriptomics provide insights into ecological niches their roles carbon, sulfur, nitrogen, hydrogen metabolism. Furthermore, our findings illustrate interplay competition cooperation among biogeochemical cycles, possibly arising overlapping functional metabolic handoffs. Taken together, study expands inhabiting provides a foundation for more incisive processes mediated ecosystems.

Chloroflexota are often abundant members of the biomass in wastewater treatment plants (WWTPs) worldwide, typically with a filamentous morphology, forming backbones activated sludge floc. However, their overgrowth can cause operational issues connected to poor settling or foaming, impairing effluent quality and increasing costs. Despite importance, few genera have been characterized so far. Here, we present comprehensive overview WWTPs worldwide an in-depth characterization phylogeny, ecophysiology, obtaining broad understanding ecological role sludge.

Abstract In globally distributed deep-sea hydrothermal vent plumes, microbiomes are shaped by the redox energy landscapes created reduced fluids mixing with oxidized seawater. Plumes can disperse over thousands of kilometers and their characteristics determined geochemical sources from vents, e.g., inputs, nutrients, trace metals. However, impacts plume biogeochemistry on oceans poorly constrained due to a lack integrated understanding microbiomes, population genetics, geochemistry. Here, we use microbial genomes understand links between biogeography, evolution, metabolic connectivity, elucidate biogeochemical cycling in deep sea. Using data 36 diverse samples seven ocean basins, show that sulfur metabolism defines core microbiome plumes drives connectivity community. Sulfur-dominated geochemistry influences promotes growth, while other influence local landscapes. We further demonstrated consistency among geochemistry, function, taxonomy. Amongst all metabolisms, transformations had highest MW-score, measure communities. Additionally, populations have low diversity, short migration history, gene-specific sweep patterns after migrating background Selected functions include nutrient uptake, aerobic oxidation, oxidation for higher yields, stress responses adaptation. Our findings provide ecological evolutionary bases change sulfur-driven communities genetics adaptation changing gradients oceans.

Abstract Background Fermented foods are considered to be beneficial for human health. Secondary metabolites determined by biosynthetic gene clusters (BGCs) precious bioactive compounds with various biological activities. However, the diversity and distribution of potential secondary in global food fermentations remain largely unknown. In this study, we performed a large-scale comprehensive investigation BGCs metagenomics analysis. Results We recovered 653 bacterial metagenome-assembled genomes (MAGs) from 367 metagenomic sequencing datasets covering 15 general fermentation types worldwide. total, 2334 metabolite BGCs, including 1003 novel were identified these MAGs. Bacillaceae, Streptococcaceae, Streptomycetaceae, Brevibacteriaceae Lactobacillaceae contained high abundances (≥ 60 BGCs). Among 1655 habitat-specific, originating habitat-specific species (80.54%) genotypes within multi-habitat (19.46%) different types. Biological activity analysis suggested that 183 BGC-producing exhibited probabilities antibacterial (> 80%). These distributed across all types, cheese most BGC number. Conclusions This study demonstrates systems an untapped reservoir metabolites, it provides insights into health benefits fermented foods.
