In-depth characterization of denitrifier communities across different soil ecosystems in the tundra

HIGHLIGHTS

• who: Igor S. Pessi from the It has been suggested that incomplete denitrifiers that contain Nir and Nor but lack Nos contribute substantially to soil ­N O emissions [26], while non-denitrifying ­N O reducers, ie., microorganisms that contain Nos but lack Nir, can represent an important N ­ O sink [27-29]. Furthermore, the partitioning of metabolic pathways across different populations with truncated pathways- also known as metabolic handoffs [30]-has been linked to higher efficiencies in substrate consumption compared to complete pathways [15, ]. However, it remains largely unclear how populations of truncated denitrifiers with different sets . . .
