Denitrification by bradyrhizobia under feast and famine and the role of the bc1 complex in securing electrons for N2O reduction

Y. Gao, M. Kjos, M. O. Arntzen, L. R. Bakken, A. Frostegard

This paper shows that bradyrhizobia retain their preference for N2O reduction over nitrate reduction under carbon starvation, suggesting they can act as N2O sinks in soils.

Suggested role of NosZ in preventing N2O inhibition of dissimilatory nitrite reduction to ammonium

S. Yoon, H. Heo, H. Han, D.-U. Song, L. R. Bakken, A. Frostegard, S. Yoon

This study investigates how N2O affects DNRA in Bacillus sp. DNRA2, finding that N2O delays DNRA transition unless removed by NosZ, suggesting nosZ retention helps prevent N2O inhibition.

A novel dual enrichment strategy provides soil- and digestate- competent N2O-respiring bacteria for mitigating climate forcing in agriculture

K. R. Jonassen, I. Ormaasen, C. Duffner, T. R. Hvidsten, A. Frostegard, L. R. Bakken, S. H. Vick

The paper develops a dual enrichment strategy to isolate N2O-respiring bacteria capable of functioning in both soil and digestate, showing their effectiveness in reducing N2O emissions.

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

A. Frostegard, S. H. Vick, N. Y. Lim, L. R. Bakken, J. P. Shapleigh

The paper links meta-omics data to denitrification intermediate kinetics, revealing pH-dependent mechanisms for N2O emissions and nitrite accumulation in soil.

N2O-respiring bacteria in biogas digestates for reduced agricultural emissions

K. R. Jonassen, L. H. Hagen, S. Vick, M. Arntzen, V. G. H. Eijsink, A. Frostegard, P. Lycus, L. Molstad, P. Pope, L. R. Bakken

This study shows that N2O-respiring bacteria can be effectively inoculated into agricultural soils using biogas digestates to reduce N2O emissions.

Competition for electrons favors N2O reduction in denitrifying Bradyrhizobium isolates

Y. Gao, D. Mania, S. A. Mousavi, P. Lycus, M. O. Arntzen, K. Lindstrom, J. P. Shapleigh, L. R. Bakken, A. Frostegard

The paper investigates denitrification in Bradyrhizobium isolates, finding that only ~1/3 can reduce N2O, with proteomics showing Nos outcompetes Nap for electrons.
