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.

The fish pathogen Aliivibrio salmonicida LFI1238 can degrade and metabolize chitin despite major gene loss in the chitinolytic pathway

A. Skane, G. Minniti, J. S. M. Loose, S. Mekasha, B. Bissaro, G. Mathiesen, M. O. Arntzen, G. Vaaje-Kolstad

This study shows that Aliivibrio salmonicida LFI1238 can degrade and metabolize chitin despite having many chitinolytic genes disrupted, using GH18 chitinase and AA10 LPMOs for this ability.
