Community Composition and Abundance of Bacterial, Archaeal and Nitrifying Populations in Savanna Soils on Contrasting Bedrock Material in Kruger National Park, South Africa [PDF]

open access: yes, 2016
Savannas cover at least 13% of the global terrestrial surface and are often nutrient limited, especially by nitrogen. To gain a better understanding of their microbial diversity and the microbial nitrogen cycling in savanna soils, soil samples were ...

Genomic and Physiological Characteristics of a Novel Nitrite-Oxidizing Nitrospira Strain Isolated From a Drinking Water Treatment Plant

open access: yesFrontiers in Microbiology, 2020
Nitrite-oxidizing bacteria (NOB) catalyze the second step of nitrification, which is an important process of the biogeochemical nitrogen cycle and is exploited extensively as a biological nitrogen removal process.

Biogeographic Patterns and Ecological Roles of Microorganisms in Sediments Along an Estuarine Salinity Gradient

open access: yesEnvironmental Microbiology Reports, Volume 17, Issue 4, August 2025.
From the river coastal to the adjacent sea waters, the diversity characteristics, community assembly processes, functional potential and community compositions of sedimentary microbial communities exhibit significant changes with increasing salinity levels.

The influence of alfalfa-switchgrass intercropping on microbial community structure and function [PDF]

open access: yes, 2021
The use of nitrogen fertilizer on bioenergy crops such as switchgrass results in increased costs, nitrogen leaching and emissions of N2O, a potent greenhouse gas.

Exploring Sulfate as an Alternative Electron Acceptor: A Potential Strategy to Mitigate N2O Emissions in Upland Arable Soils

open access: yesGlobal Change Biology, Volume 31, Issue 8, August 2025.
This study explored the use of sulfate‐based soil amendments as a new method to mitigate N2O—a powerful greenhouse gas—from agricultural soils. Laboratory and field experiments showed sulfate treatments significantly lowered N2O emissions without negatively affecting crop yields, mainly by altering soil microbial processes.

Sediments From a Seasonally Euxinic Coastal Ecosystem Show High Nitrogen Cycling Potential

open access: yesEnvironmental Microbiology, Volume 27, Issue 7, July 2025.
The nitrogen cycling potential of sediments from seasonally euxinic Lake Grevelingen was investigated through incubation experiments and 16S rRNA amplicon and shotgun metagenome sequencing. The sediments have a high potential for nitrification, denitrification, and DNRA, but not for anammox. ABSTRACT Coastal ecosystems are susceptible to eutrophication

Composition and activity of nitrifier communities in soil are unresponsive to elevated temperature and CO2, but strongly affected by drought [PDF]

open access: yes, 2020
Nitrification is a fundamental process in terrestrial nitrogen cycling. However, detailed information on how climate change affects the structure of nitrifier communities is lacking, specifically from experiments in which multiple climate change factors ...

Nitrogen source influences the interactions of comammox bacteria with aerobic nitrifiers

open access: yesMicrobiology Spectrum
While the co-existence of comammox Nitrospira with canonical nitrifiers is well documented in diverse ecosystems, there is still a dearth of knowledge about the mechanisms underpinning their interactions.

Recent Advances in Aquaponic Systems: A Critical Review

open access: yesReviews in Aquaculture, Volume 17, Issue 3, June 2025.
This article critically examines recent advances in aquaponic systems, identifies knowledge gaps, and proposes future research directions to enhance system performance, economic viability, and environmental sustainability. ABSTRACT Aquaponics, a symbiotic farming of plants and fish, is a promising solution to address global food security.

Growth of comammox Nitrospira is inhibited by nitrification inhibitors in agricultural soils [PDF]

open access: yesJournal of Soils and Sediments, 2019
The discovery of comammox Nitrospira being capable of complete oxidising ammonia to nitrate radically challenged the conventional concept of two-step nitrification. However, the response of comammox Nitrospira to nitrification inhibitors (NIs) and their role in soil nitrification remain largely unknown, which has hindered our ability to predict the ...
