Linking meta-omics to the kinetics of denitrification intermediates reveals pH-dependent causes of N2O emissions and nitrite accumulation in soil

Å Frostegård, SHW Vick, NYN Lim, LR Bakken… - The ISME …, 2022 - academic.oup.com
Soil pH is a key controller of denitrification. We analysed the metagenomics/transcriptomics
and phenomics of two soils from a long-term liming experiment, SoilN (pH 6.8) and un-limed …

Nitrous oxide-sink capability of denitrifying bacteria impacted by nitrite and pH

Y Zhou, S Zhao, T Suenaga, M Kuroiwa, S Riya… - Chemical Engineering …, 2022 - Elsevier
Nitrous oxide (N 2 O) is a highly potent greenhouse gas and ozone-depleting substance,
