Bradyrhizobia are common members of soil microbiomes and known as N2‐fixing symbionts
of economically important legumes. Many are also denitrifiers, which can act as sinks or …

Bradyrhizobia are abundant soil bacteria, which can form nitrogen‐fixing symbioses with
leguminous plants, including important crops such as soybean, cowpea and peanut. Many …

Emissions of the potent greenhouse gas N2O is one of the environmental problems
associated with intensive use of synthetic N fertilizers, and novel N2O mitigation strategies …

When soil oxygen levels decrease, some bradyrhizobia use denitrification as an alternative
form of respiration. Bradyrhizobium diazoefficiens (nos+) completely denitrifies nitrate (NO …

Publisher Summary This chapter describes the denitrification in rhizobia legume symbiosis
and provides an update on the progress on denitrification by free-living and symbiotic …

To clarify the genetic basis to the diversity of denitrifying ability in soybean bradyrhizobia, we
compared the end-products of denitrification (N2, N2O and NO2−) with the existence of …

Aims Greenhouse gases are considered as potential atmospheric pollutants, with agriculture
being one of the main emission sources. The practice of inoculating soybean seeds with …

To understand the mechanisms underlying the increased N2O reductase activity in the
Bradyrhizobium japonicum 5M09 mutant from enrichment culture under N2O respiration, we …

Denitrification is the complete reduction of nitrate or nitrite to N2, via the intermediates nitric
oxide (NO) and nitrous oxide (N2O), and is coupled to energy conservation and growth …

More than two-thirds of the powerful greenhouse gas nitrous oxide (N2O) emissions from
soils can be attributed to microbial denitrification and nitrification processes. Bacterial …
