The Microbial Nitrogen Cycle [PDF]

open access: yesFrontiers in Microbiology, 2014
Nitrogen is an essential element in biological systems, and one that often limits production in both aquatic and terrestrial systems. Due to its requirement in biological macromolecules, its acquisition and cycling have the potential to structure microbial communities, as well as to control productivity on the ecosystem scale.

Cyclic Conversions in the Nitrogen Cycle [PDF]

open access: yesFrontiers in Microbiology, 2021
The cyclic nature of specific conversions in the nitrogen cycle imposes strict limitations to the conversions observed in nature and explains for example why anaerobic ammonium oxidation (anammox) bacteria can only use nitrite – and not nitrate – as ...

Straw mulch improves soil carbon and nitrogen cycle by mediating microbial community structure and function in the maize field [PDF]

open access: yesFrontiers in Microbiology, 2023
This study was conducted to investigate the capability of the microbial community characteristics and soil variables to promote carbon and nitrogen cycles in maize fields under straw mulch.

Light-driven integration of diazotroph-derived nitrogen in euphotic nitrogen cycle [PDF]

open access: yesNature Communications
The bioavailable nitrogen fixed by diazotrophs is critical for sustaining productivity in the oligotrophic ocean. Despite this, understanding how diazotroph-derived nitrogen integrates into the nitrogen cycle within the euphotic zone remains unknown ...

The spatial distribution and biogeochemical drivers of nitrogen cycle genes in an Antarctic desert [PDF]

open access: yesFrontiers in Microbiology, 2022
Antarctic deserts, such as the McMurdo Dry Valleys (MDV), represent extremely cold and dry environments. Consequently, MDV are suitable for studying the environment limits on the cycling of key elements that are necessary for life, like nitrogen.

Nitrogen Cycle in Farming Systems

open access: yesAgronomy, 2023
The challenge for people currently living on Earth is to develop a food production strategy to cover the food gap and at the same time maintain or even improve the soil use production potential [...]

Comparison and Selection of Conventional PCR Primer Sets for Studies Associated with Nitrogen Cycle Microorganisms in Surface Soil

open access: yesApplied Sciences, 2022
The nitrogen cycle is a biogeochemical cycle primarily associated with the microbial activity that occurs in various environments, including soil. Various genes related to the nitrogen cycle have been studied for different purposes by many researchers ...

The nitrogen cycle [PDF]

open access: yesCurrent Biology, 2016
Nitrogen is the fourth most abundant element in cellular biomass, and it comprises the majority of Earth's atmosphere. The interchange between inert dinitrogen gas (N2) in the extant atmosphere and 'reactive nitrogen' (those nitrogen compounds that support, or are products of, cellular metabolism and growth) is entirely controlled by microbial ...

Post-depositional loss of nitrate and chloride in Antarctic snow by photolysis and sublimation: a field investigation

open access: yesPolar Research, 2020
Nitrate in snow is subject to post-depositional processing, which leads to a net loss and redistribution within the snowpack. The relative importance of post-depositional loss processes such as the volatilization of nitric acid (HNO3) and photolysis of ...

A Synthesis of Viral Contribution to Marine Nitrogen Cycling

open access: yesFrontiers in Microbiology, 2022
Nitrogen is an essential component of major cellular macromolecules, such as DNA and proteins. Its bioavailability has a fundamental influence on the primary production of both terrestrial and oceanic ecosystems. Diverse marine microbes consume nitrogen,
