An overlooked microbial pathway links organic nitrogen turnover in composts to nitrous oxide formation

The paper identifies an alternative microbial pathway for N2O formation in composts that bypasses canonical nitrification, linking organic nitrogen turnover to denitrification.

Flavobacteria buffer nitrous oxide emissions from partial denitrifiers in coastal sediments

The paper identifies Flavobacteria in coastal sediments that reduce nitrous oxide emissions by having low substrate affinity, contradicting prior assumptions and suggesting they buffer nitrogen cycling.

Selective enrichment of high-affinity clade II N2O-reducers in a mixed culture

The paper shows clade II N2O-reducers outcompete clade I under low N2O availability, and coexist under high N2O, with cobalamin interactions influencing community composition.

Hydrogen-dependent dissimilatory nitrate reduction to ammonium enables growth of Campylobacterota isolates

This study isolates two Campylobacterota strains that use molecular hydrogen as an electron donor for dissimilatory nitrate reduction to ammonium, challenging the traditional C:N ratio paradigm.

Selective enrichment of Methylococcaceae versus Methylocystaceae methanotrophs via control of methane feeding scheme

This study enriches methanotrophic microbiomes from paddy soils under different methane and copper conditions, finding Methylocystis dominance and ecological importance of methanobactin in Cu-deficient environments.
