Interactions between fungi and bacteria have the potential to substantially influence soil carbon dynamics in soil, but we yet fully identify these interactions partners their natural environment. In this study, stacked two powerful methods, 13C quantitative stable isotope probing (qSIP) cross-domain co-occurrence network, interacting a California grassland soil. We used in-field whole plant 13CO2 labeling along with sand-filled ingrowth bags (that trap hyphae-associated bacteria) amplify signal of fungal-bacterial interactions, separate from bulk background. found total 54 bacterial ASVs 9 fungal OTUs that were significantly 13C-enriched. These saprotrophic biotrophic fungi, motile, sometimes predatory bacteria. Among these, 70% all 13C-enriched identified motile. Notably, detected network links OTU genus Alternaria several genera Bacteriovorax, Mucilaginibacter, Flavobacterium, providing empirical evidence direct through C exchange. observed strong positive pattern phylum Bdellovibrionota OTUs, suggesting transfer across food web. To date, our ability associate microbial patterns biological is limited, incorporation qSIP allowed us more precisely detect by narrowing on taxa actively incorporating plant-fixed, fungal-transported labeled substrates. Together, approaches can help build mechanistic understanding complex nature

Abstract Activated sludge is the centerpiece of biological wastewater treatment, as it facilitates removal sewage-associated pollutants, fecal bacteria, and pathogens from through semi-controlled microbial ecology. It has been hypothesized that horizontal gene transfer spread antibiotic resistance genes within treatment plant, in part because presence residual antibiotics sewage. However, there surprisingly little evidence to suggest select for at plants via or otherwise. We addressed role promoting using lab-scale sequencing batch reactors fed field-collected wastewater, metagenomic sequencing, our recently developed bioinformatic tool Kairos. Here, we found confirmatory fluctuating levels sewage are associated with genes, ecology, microdiversity-level differences fate activated sludge.

Rhizodegradation enhances pollutant degradation through plant–microbe interactions in the rhizosphere. Plant roots provide a colonisation surface and root exudates that promote microbial abundance activity, facilitating organic breakdown via direct co-metabolism. This study assessed rhizodegradation of weathered petroleum hydrocarbons (PHCs) heavy metal co-contaminated soil microcosm-scale pot trial. Treatments included Sinapis alba, Lolium perenne, L. perenne + Trifolium repens mix, Cichorium intybus, alongside non-planted control. After 14 weeks, PHC concentrations were analysed gas chromatography, rhizosphere communities characterised sequencing. alba achieved highest (68%), significantly exceeding control (p < 0.05, Kruskal–Wallis test). Hydrocarbon-degrading bacteria, including KCM-B-112, C1-B045, Hydrogenophaga, unclassified Saccharimonadales sp., Pedobacter, enriched rhizosphere, with uncultured clade mle1-27 potentially contributing indirectly. Metals analysis plant tissues showed mustard could accumulate copper more than lead zinc, despite higher zinc soil. These results highlight potential S. for rhizoremediation PHC–heavy soils.

Deciphering unclear microbial interactions is key to improving biological wastewater treatment processes. Microbial predation and parasitism in ecosystems are unexplored survival strategies that have long been known recently attracted attention because these interspecies may contribute the reduction of excess sludge. Here, community profiling 600 activated sludge samples taken from six industrial one municipal processes (WWTPs) was conducted. To identify shared lineages WWTPs, constituents were defined as family level taxa had ≥ 0.1% average relative abundance detected all The analysis assigned 106 families WWTPs. Correlation showed 98 significantly correlated with total carbon (TC) and/or nitrogen (TN) concentrations, suggesting they remediation. Most possible predatory or parasitic bacteria belonging phyla Bdellovibrionota, Myxococcota, Candidatus Patescibacteria found be negatively TC/TN; thus, frequently present WWTPs could involved removal carbon/nitrogen derived cell components. Shotgun metagenome-resolved metabolic reconstructions indicated gene homologs associated conserved Ca. genomes (e.g., host interaction (hit) locus, Tad-like secretion complexes, type IV pilus assembly proteins). This study provides insights into complex potentially linked biomass
