Biological nitrogen fixation in rhizobia occurs primarily in root or stem nodules and is
induced by the bacteria present in legume plants. This symbiotic process has fascinated …

While large inputs of synthetic nitrogen fertilizers enable our current rate of crop production
and feed a growing global population, these fertilizers come at a heavy environmental cost …

Denitrification–a key process in the global nitrogen cycle and main source of the
greenhouse gas N2O–is intricately controlled by O2. While the transition from aerobic …

N2O is an important greenhouse gas influencing global warming, and agricultural land is the
predominant (anthropogenic) source of N2O emissions. Here, we report the high N2O …

Soil pH is a key controller of denitrification. We analysed the metagenomics/transcriptomics
and phenomics of two soils from a long-term liming experiment, SoilN (pH 6.8) and un-limed …

Inoculating agricultural soils with nitrous oxide respiring bacteria (NRB) can reduce N2O-
emission, but would be impractical as a standalone operation. Here we demonstrate that …

Nitrous oxide (N 2 O) is a highly potent greenhouse gas and ozone-depleting substance,
produced and consumed during denitrification. Evaluation of the N 2 O production and …

In denitrifying reactors, canonical complete denitrifying bacteria reduce nitrate (NO3–) to
nitrogen via N2O. However, they can also produce N2O under certain conditions. We used a …

Improved understanding of the microbes producing and reducing N 2 O spurs the invention
of direct and manipulative methods to reduce N 2 O emissions, beyond that achieved by …

Manipulating soil metabolism through heavy inoculation with microbes is feasible if organic
wastes can be utilized as the substrate for growth and vector as a fertilizer. This, however …
