This paper reviews dissimilatory nitrate reduction to ammonium (DNRA) in soils-a newly
appreciated pathway of nitrogen (N) cycling in the terrestrial ecosystems. The reduction of …

Understanding aerobic denitrification has become an important focus of environmental
microbiology. Aerobic denitrification can be performed by various genera of microorganisms …

The understanding of nitrogen (N) cycling in forest ecosystems has undergone a major shift
in the past decade as molecular methods are being used to link microorganisms to key …

Nitrous oxide (N 2 O) is mainly generated via nitrification and denitrification processes in
soils and subsequently emitted into the atmosphere where it causes well-known radiative …

Present-day knowledge on the regulatory biology of denitrification is based on studies of
selected model organisms. These show large variations in their potential contribution to …

The microbial processes of denitrification and dissimilatory nitrate reduction to ammonium
(DNRA) are two important nitrate reducing mechanisms in soil, which are responsible for the …

Denitrifiers differ in how they handle the transition from oxic to anoxic respiration, with
consequences for NO and N2O emissions. To enable stringent comparisons we defined …

Denitrifying prokaryotes use NOx as terminal electron acceptors in response to oxygen
depletion. The process emits a mixture of NO, N2O and N2, depending on the relative …

Denitrification in soil is a major source of atmospheric N2O. Soil pH appears to exert a
strong control on the N2O/N2 product ratio (high ratios at low pH), but the reasons for this …

ABSTRACT A major percentage (20 to 40%) of global marine fixed-nitrogen loss occurs in
oxygen minimum zones (OMZs). Concentrations of O2 and the sensitivity of the anaerobic …
