The microbial nitrogen-cycling network [PDF]

open access: yesNature Reviews Microbiology, 2018
Nitrogen is an essential component of all living organisms and the main nutrient limiting life on our planet. By far, the largest inventory of freely accessible nitrogen is atmospheric dinitrogen, but most organisms rely on more bioavailable forms of nitrogen, such as ammonium and nitrate, for growth.

Microbial Nitrogen Cycling in Antarctic Soils. [PDF]

open access: yesMicroorganisms, 2020
The Antarctic continent is widely considered to be one of the most hostile biological habitats on Earth. Despite extreme environmental conditions, the ice-free areas of the continent, which constitute some 0.44% of the total continental land area, harbour substantial and diverse communities of macro-organisms and especially microorganisms, particularly

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.

Microbial nitrogen bubble formation in porous media. [PDF]

open access: yesHeliyon
Microbially induced nitrogen (N2) gas bubbles can desaturate subsurface areas and thus have been considered as an alternative ground improvement technique for mitigating soil liquefaction potential caused by earthquakes. However, the detailed mechanisms of subsurface N2 bubbles are not well understood and remain a subject of ongoing research.

Appropriate Nitrogen Addition Boosts Coastal Wetland Carbon Sequestration: Kandelia obovata Optimizes Microbial Carbon Use Strategies [PDF]

open access: yesPlants
Mangrove ecosystems in coastal wetland restoration areas are experiencing escalating nitrogen stress, yet the microbial metabolic mechanisms underlying soil carbon sequestration in Kandelia obovata systems under exogenous nitrogen input remain unclear ...

Microbial nitrogen limitation in the mammalian large intestine. [PDF]

open access: yesNat Microbiol, 2018
Resource limitation is a fundamental factor governing the composition and function of ecological communities. However, the role of resource supply in structuring the intestinal microbiome has not been established and represents a challenge for mammals that rely on microbial symbionts for digestion: too little supply might starve the microbiome while ...

Seasonal variations drive microbial community structure and nitrogen cycling in sediments of tributary pumping station forebays [PDF]

open access: yesMicrobiology Spectrum
Discharge from tributary pumping stations often impacts mainstream water quality, yet microbial communities and nitrogen metabolism in pumping station forebays remain poorly understood. Therefore, this study investigated the microbial community structure

Functional annotation of proteins for signaling network inference in non-model species

open access: yesNature Communications, 2023
Molecular biology aims to understand cellular responses and regulatory dynamics in complex biological systems. However, these studies remain challenging in non-model species due to poor functional annotation of regulatory proteins.

Conversion of Plant Nitrogen to Microbial Nitrogen in the Rumen of the Sheep [PDF]

open access: yesNature, 1953
PLANT protein in the fodder of ruminants does not arrive unaltered at the abomasum where peptic digestion takes place; there can be no doubt that at least a part of it is degraded, and later resynthesized to microbial protein by the enormous numbers of bacteria and other micro-organisms in the rumen.

Enhanced atmospheric nitrogen deposition triggered little change in soil microbial diversity and structure in a desert ecosystem

open access: yesGlobal Ecology and Conservation, 2021
Enhanced atmospheric nitrogen deposition can greatly influence the soil nitrogen content and soil microorganisms in terrestrial ecosystems. However, there is a lack of knowledge about the response of soil microbes to changes in soil nitrogen ...
