Tillage does not impact soil greenhouse gas emissions in a Central Texas rainfed maize–cotton system

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Agricultural soils are a significant source of greenhouse gas (GHG) emissions, primarily as N2O. Monitoring how management practices impact soil gas fluxes (CO2, CH4, and N2O) is useful for making sure conservation practices (e.g., no‐till) are sustainable with regards to all potential environmental impacts.

Emergent Macrophytes Act Selectively on Ammonia-Oxidizing Bacteria and Archaea [PDF]

open access: yesApplied and Environmental Microbiology, 2012
ABSTRACT Ammonia-oxidizing bacteria (AOB) and archaea (AOA) were quantified in the sediments and roots of dominant macrophytes in eight neutral to alkaline coastal wetlands. The AOA dominated in most samples, but the bacterial-to-archaeal amoA gene ratios increased with increasing ammonium levels and pH in

Abundance and diversity of nitrogen-removing microorganisms in the UASB-anammox reactor.

open access: yesPLoS ONE, 2019
Anaerobic ammonium oxidation is considered to be the most economical and low-energy biological nitrogen removal process. So far, anammox bacteria have not yet been purified from cultures.

Artificial intelligence driven diet‐intestinal microbiota‐host health integration: A four‐dimensional paradigm for advancing host wellness research

open access: yesiMetaOmics, Volume 3, Issue 3, September 2026.
This graphical abstract presents a novel Diet‐Artificial Intelligence (AI)‐intestinal Microbiota–Host Health paradigm integrating microbiota‐centric pathways and an AI‐driven multi‐omics workflow. Diet shapes gut bacteria that regulate intestinal mucosal integrity, immune signaling, and gut–brain neurotransmitters to influence host health.

Hydroxylamine as an intermediate in ammonia oxidation by globally abundant marine archaea [PDF]

open access: yesProceedings of the National Academy of Sciences, 2012
The ammonia-oxidizing archaea have recently been recognized as a significant component of many microbial communities in the biosphere. Although the overall stoichiometry of archaeal chemoautotrophic growth via ammonia (NH 3 ) oxidation to nitrite (NO 2 −

Indigenous Ammonia-Oxidizing Archaea in Oxic Subseafloor Oceanic Crust

open access: yesmSystems, 2020
Oceanic ridge flank systems represent one of the largest and least-explored microbial habitats on Earth. Fundamental ecological questions regarding community activity, recruitment, and succession in this environment remain unanswered.

Iron/Manganese Oxide‐Bound Nitrogen Suppresses Microbial Mediated Nitrate Reduction in Soil

open access: yesLand Degradation &Development, Volume 37, Issue 15, Page 10784-10794, September 2026.
ABSTRACT Nitrogen cycling plays a pivotal role in sustaining ecosystem productivity and stability, while the chemical forms of nitrogen in soils critically influence both its efficiency and pathways. In this study, farmland soils from the Anning River Basin—an important watershed in Southwest China—were investigated to examine the regulatory effects of

Ergothioneine: Biosynthesis, Molecular Mechanisms, Physiological Function, and Role in Disease

open access: yesMedComm, Volume 7, Issue 9, September 2026.
Ergothioneine is a natural thione antioxidant with significant biomedical potential. By reducing oxidative stress, inflammation, mitochondrial dysfunction, and cellular injury, ergothioneine may support interventions for aging‐related disorders, neurodegeneration, metabolic diseases, and skin protection.

Ammonia manipulates the ammonia-oxidizing archaea and bacteria in the coastal sediment-water microcosms

open access: yes, 2015
Ammonia was observed as a potential significant factor to manipulate the abundance and activity of ammonia-oxidizing microorganisms (AOMs) in water environments. For the first time, this study confirmed this phenomenon by laboratory cultivation.

ADP-dependent Phosphofructokinases in Mesophilic and Thermophilic Methanogenic Archaea [PDF]

open access: yes, 2001
Phosphofructokinase (PFK) is a key enzyme of the glycolytic pathway in all domains of life. Two related PFKs, ATP-dependent and PPi-dependent PFK, have been distinguished in bacteria and eucarya, as well as in some archaea.
