Life on N₂O: deciphering the ecophysiology of N₂O respiring bacterial communities in a continuous culture

Reduction of the greenhouse gas N₂O to N₂ is a trait among denitrifying and non-denitrifying microorganisms having an N₂O reductase, encoded by nosZ. The nosZ phylogeny has two major clades, I and II, and physiological differences among organisms within the clades may affect N₂O emissions from...

Growth yield and selection of nosZ clade II types in a continuous enrichment culture of N₂O respiring bacteria

Nitrous oxide (N₂O) reducing microorganisms may be key in the mitigation of N₂O emissions from managed ecosystems. However, there is still no clear understanding of the physiological and bioenergetic implications of microorganisms possessing either of the two N₂O reductase genes (nosZ), clade I and the more...
