Understanding the reaction mechanism of dissolved organic matter (DOM) during wastewater biotreatment is crucial for optimal DOM control. Here, we develop a directed paired mass distance (dPMD) method that constructs molecular network displaying pathways DOM. It couples direction inference and PMD analysis to extract substrate–product relationships delta masses potentially reactants directly from sequential spectrometry data without formula assignment. Using this method, analyze influent effluent samples bioprocesses 12 treatment plants (WWTPs) build dPMD characterize core reactome The shows first step transformation triggers cascades diversify DOM, but highly overlapped subsequent result in similar compositions across WWTPs despite varied influents. Mass changes exhibit consistent gain/loss preferences (e.g., +3.995 −16.031) different occurrences WWTPs. Combined with genome-centric metatranscriptomics, reveal associations among dPMDs, enzymes, microbes. Most enzymes are involved oxygenation, (de)hydrogenation, demethylation, hydration-related reactions target substrates expressed by various taxa, as exemplified Proteobacteria, Actinobacteria, Nitrospirae. Therefore, functionally diverse community pivotal advanced degradation.

Methane metabolism, driven by methanogenic and methanotrophic microorganisms, plays a pivotal role in the carbon cycle. As seawater intrusion soil salinization rise due to global environmental shifts, understanding how salinity affects methane emissions, especially deep strata, becomes imperative. Yet, insights into stratigraphic release under varying conditions remain sparse. Here we investigate effects of on metabolism across terrestrial coastal strata (15-40 m depth) through

With the development of global industrialization, carbon neutrality has become an issue that we must be paid attention to. Microorganisms not only have important impact on chemical cycle between Earth's biosphere and biogeography but also play a key role in maintaining organic balance. Wetlands are main reservoir mainland China, wetland sinks indispensable for China to achieve goal "dual carbon," taken consolidation improvement sink capacity as part peaking action plan. As unique low-latitude, high-altitude seasonal plateau Napahai shows high research value. However, microbes dissolved balance this area been reported. In study, six fixation genes, accA, aclB, acsA, acsB, cbbL, rbcL, were analyzed based metagenomics elucidate rich genetic diversity, uniqueness differences wetland. It was found microbial diversity different from other habitats. addition, aclB gene, rare taxon with species wetland, played metabolic pathway. Finally, construction pathway through Kyoto encyclopedia genes genomes revealed contribution

Wetland microbial communities play a vital role in ecosystem functioning, particularly the intricate processes of carbon cycling. This study employed metagenomic sequencing to investigate diversity, composition, structural differences, cycling functional gene, and species soil five distinct types Yalu River estuary wetland, including shoal soil, bog paddy meadow brown forest soil. We further explored influence environmental factors on both community structure genes. Our results revealed bacterial-dominated community, constituting about 97.6%. Archaea fungi represented relatively minor fractions, at 1.9% 0.4%, respectively. While no significant differences were observed Chao1 indices between bacterial fungal communities, Shannon index notable differences. Both exhibited variations within archaeal communities. The dominant phyla Proteobacteria, Actinobacteria, Acidobacteria, Bacteroidetes, Nitrospirae. Thaumarchaeota, Crenarchaeota, Euryarchaeota formed major phyla, while Ascomycota, Mucoromycota, Basidiomycota phyla. Non-metric multidimensional scaling (NMDS) analysis based Bray-Curtis distance bacterial, archaeal, structures across samples. Redundancy (RDA) identified key for Soil pH, organic (SOC), electrical conductivity (EC), total phosphorus (TP) main influencing bacteria, TP, EC, sulfur (TS), SOC primary drivers nitrogen (TN) EC Analysis pathway genes utilizing Kyoto Encyclopedia Genes Genomes (KEGG) database clustering heatmap some gene composition different types. Mantel test indicated that TN, associated with Stratified bar chart demonstrated contributors originated from corresponding dominatnt genera Actinomycetota, Euryarchaeota, Bacteroidota. relative abundance microorganisms pathways varied among These findings provide crucial reference informing conservation sustainable management wetland ecosystems estuary.
