Chemical formation of hybrid di-nitrogen calls fungal codenitrification into question.

ABSTRACT: Removal of excess nitrogen (N) can best be achieved through denitrification processes that transform N in water and terrestrial ecosystems to di-nitrogen (N₂) gas. The greenhouse gas nitrous oxide (N₂O) is considered an intermediate or end-product in denitrification pathways. Both abiotic and biotic denitrification processes use a single N source to form N₂O. However, N₂ can be formed from two distinct N sources (known as hybrid N₂) through biologically mediated processes of anammox and codenitrification. We questioned if hybrid N₂ produced during fungal incubation at neutral pH could be attributed to abiotic nitrosation and if N₂O was consumed during N₂ formation.
