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.

This study isolates a halophilic methanotroph capable of converting surplus methane into ectoine, a high-value compound, under optimized conditions.

The paper uses metagenomics and metatranscriptomics to identify bacteria involved in N2O mitigation and ammonification in a bioreactor, showing how oxygen levels affect their activity.
