Ammonia oxidizers offset acidification stress via adaptive substrate affinity in aquatic ecosystems

Nature Communications
Ammonia oxidation, a critical nitrogen cycle process, exhibits contradictory responses to aquatic acidification, and the underlying mechanism remains unresolved. Here, through pH manipulation experiments across diverse ecosystems and with a model ammonia-

Enhancing Meat Quality Through Dietary Fiber: Insights Into the Gut Microbiota‐Derived Short‐Chain Fatty Acids‐Muscle Axis

Animal Research and One Health, EarlyView.
Dietary fiber (DF) modulates meat quality through the gut‐muscle axis by reshaping gut microbiota, improving intestinal integrity, reducing inflammation, and regulating muscle metabolism. These mechanisms influence muscle fiber characteristics and post‐mortem biochemistry, thereby enhancing tenderness, juiciness, color, flavor, and nutritional value of

Ammonia-oxidizing archaea and ammonia-oxidizing bacteria in six full-scale wastewater treatment bioreactors [PDF]

Applied Microbiology and Biotechnology, 2011
In this study, dideoxy sequencing and 454 high-throughput sequencing were used to analyze diversities of the ammonia monooxygenase (amoA) genes and the 16S rRNA genes of ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB) in six municipal wastewater treatment plants.

Selective Enrichment of Nitrososphaera viennensis-Like Ammonia-Oxidizing Archaea over Ammonia-Oxidizing Bacteria from Drinking Water Biofilms

Microbiology Spectrum, 2022
Ammonia-oxidizing archaea (AOA) can oxidize ammonia to nitrite for energy gain. They have been detected in chloraminated drinking water distribution systems (DWDS) along with the more common ammonia-oxidizing bacteria (AOB) and nitrite-oxidizing bacteria

The Role of Iron‐Hyponitrite Intermediates in Biology and Insights From Synthetic Model Complexes

Chemistry – A European Journal, EarlyView.
Despite the difference in active site architecture, NO reduction by different NOR enzymes is expected to be linked by a common intermediate: hyponitrite (N2O22−). However, experimentally, very little is known about the coordination chemistry of iron with hyponitrite and the expected Fe‐hyponitrite intermediates.

Immobilization of active ammonia-oxidizing archaea in hydrogel beads

npj Clean Water, 2021
Ammonia-oxidizing archaea (AOA) are major players in the nitrogen cycle but their cultivation represents a major challenge due to their slow growth rate and limited tendency to form biofilms. In this study, AOA was embedded in small (~2.5 mm) and large (~

The plant microbiome: From ecological foundations to precision microbial engineering for sustainable agriculture

iMeta, EarlyView.
From ecological principles to precision engineering of plant microbiomes for sustainable agriculture. The plant holobiont integrates diverse microbial niches (including rhizosphere, endosphere, phyllosphere, seed, and aerial‐root mucilagesphere), host genetics (namely M genes), and host metabolites. Furthermore, molecular dialogues, including rhizobial

Relative contributions of archaea and bacteria to aerobic ammonia oxidation in the environment [PDF]

Environmental Microbiology, 2008
Summary Traditionally, organisms responsible for major biogeochemical cycling processes have been determined by physiological characterization of environmental isolates in laboratory culture. Molecular techniques have, however, confirmed the widespread occurrence of abundant bacterial and archaeal groups with no cultivated ...

Exploring protein N-glycosylation in ammonia-oxidizing Nitrososphaerota archaea through glycoproteomic analysis

mBio
Ammonia-oxidizing archaea of the phylum Nitrososphaerota, formerly known as Thaumarchaeota, are globally distributed and play critical roles in the nitrogen and carbon cycles, particularly in environments with low ammonia concentrations.
