Potential survival strategies of novel comammox and nitrite-oxidizing Nitrospira present in a reactor treating high-ammonia brackish landfill leachate

The paper identifies novel nitrifiers in a brackish landfill leachate treatment system, including a comammox Nitrospira and new sub-lineage VII Nitrospira, and explores their metabolic adaptations.

Is it selfish to be filamentous in biofilms? Individual-based modeling links microbial growth strategies with morphology using the new and modular iDynoMiCS 2.0

The paper introduces iDynoMiCS 2.0, an individual-based modeling platform for microbial communities, showing that filamentous bacteria outcompete spherical bacteria regardless of growth strategy.

Ancient electrogenic survival metabolism of β-proteobacterial ammonia oxidizers for oxygen deficiency

This paper demonstrates that aerobic β-proteobacterial ammonia oxidizers can perform anaerobic extracellular electron transfer (EET) and reconstructs the evolutionary history of this metabolism under fluctuating oxygen levels.

Different autotrophic enrichments yield efficient inocula for biocathodic applications

The paper investigates microbial guilds enriched on different substrates to identify those capable of extracellular electron uptake and assess their efficiency.

Temperature modulates stress response in anammox reactors

The paper examines how temperature affects the stress response of anammox bacteria in wastewater treatment under oxygen fluctuations.

Pathogenic and Indigenous Denitrifying Bacteria are Transcriptionally Active and Key Multi-Antibiotic Resistant Players in Wastewater Treatment Plants

The paper analyzes ARG hosts in WWTPs using metatranscriptomics, finding 45% of genomes express multi-antibiotic resistance genes, with pathogens and denitrifying bacteria as key hosts.

Extended spectrum β-lactamase and carbapenemase genes are substantially and sequentially reduced during conveyance and treatment of urban sewage

The paper quantifies the reduction of antibiotic resistance genes during urban sewage conveyance and treatment, showing greater removal occurs during conveyance than treatment.

Evolutionary ecology of natural comammox Nitrospira populations

This study examines evolutionary dynamics of comammox Nitrospira populations in groundwater-fed sand filters, finding strong purifying selection and low recombination, suggesting habitat type strongly influences evolution.

Plasmids persist in a microbial community by providing fitness benefit to multiple phylotypes

This study shows that plasmids can persist in microbial communities by providing fitness benefits to multiple bacterial phylotypes, enabling long-term community-wide access to antibiotic resistance genes.

DNA and RNA-SIP reveal Nitrospira spp. as key drivers of nitrification in groundwater-fed biofilters

The paper uses DNA and RNA-SIP with 16S rRNA sequencing to identify Nitrospira as key ammonia and nitrite oxidizers in groundwater-fed biofilters.

Genomic profiling of Nitrospira species reveals ecological success of comammox Nitrospira

The paper establishes the largest Nitrospira genome database, revealing ecological dominance and genomic diversity of comammox Nitrospira across environments.

Comparative Genomics Sheds Light On Niche Differentiation And The Evolutionary History Of Comammox Nitrospira

This paper presents the first comparative genomic analysis of comammox Nitrospira, revealing their unique adaptations to oligotrophy and hypoxia and tracing the evolutionary origins of their ammonium oxidation pathway from beta-AOB.
