Abstract

Denitrifying bacteria have evolved elaborate regulatory networks securing their respiratory metabolism in environments with fluctuating oxygen concentrations. Here, we provide new insight regarding their bet-hedging in response to hypoxia, which minimizes their N 2 O emissions because all cells express NosZ, reducing N 2 O to N 2 , while a minority express NirS + Nor, reducing NO 2 − to N 2 O.
