Diversity, Physiology, and Niche Differentiation of Ammonia-Oxidizing Archaea [PDF]

Applied and Environmental Microbiology, 2012
ABSTRACT Nitrification, the aerobic oxidation of ammonia to nitrate via nitrite, has been suggested to have been a central part of the global biogeochemical nitrogen cycle since the oxygenation of Earth. The cultivation of several ammonia-oxidizing archaea (AOA) as well as the discovery that archaeal ammonia monooxygenase (

Occurrence of Ammonia-Oxidizing Archaea in Wastewater Treatment Plant Bioreactors [PDF]

Applied and Environmental Microbiology, 2006
ABSTRACT We report molecular evidence that ammonia-oxidizing archaea (AOA) occur in activated sludge bioreactors used to remove ammonia from wastewater. Using PCR primers targeting archaeal ammonia monooxygenase subunit A ( amoA ) genes, we retrieved and compared 75 sequences from five wastewater treatment

Research progress on the physiological metabolic mechanisms and distribution in water treatment systems of ammonia-oxidizing microorganisms

Gongye shui chuli
Nitrification and denitrification processes play crucial roles in biological nitrogen removal in water treatment systems. The ammonia oxidation in nitrification is the rate-limiting process, which converts low-valent ammonia-nitrogen into high-valent ...

Evaluation of combined root exudate and rhizosphere microbiota sampling approaches to elucidate plant–soil–microbe interactions

New Phytologist, EarlyView.
Summary Deciphering the root exudate‐driven interplay between plants and the rhizosphere microbiota is essential for understanding plant adaptation to the environment and future‐proofing crop production. However, sampling root exudates and rhizosphere soil remains challenging due to the low throughput and destructive nature of the process.

Subterranean environments contribute to three‐quarters of classified ecosystem services

Biological Reviews, Volume 101, Issue 3, Page 1582-1605, June 2026.
ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.

The Elbe Estuary Microbiome Shifts With Salinity and Discharge and Depends on Fresh Organic Matter and Nutrient Availability

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Microbial diversity within the Elbe Estuary was found to be more strongly governed by seasonal variability, salinity, and discharge than by spatial heterogeneity. Oligohaline regions sustain high diversity, while nutrient and redox conditions drive functional shifts.

Microbial communities and bioactive compounds in marine sponges of the family Irciniidae-a review [PDF]

, 2014
Marine sponges harbour complex microbial communities of ecological and biotechnological importance. Here, we propose the application of the widespread sponge family Irciniidae as an appropriate model in microbiology and biochemistry research. Half a gram

Production Performance and Ameliorative Effects of Switchgrass on Severely Saline‐Alkali Land in Coastal Areas of China

GCB Bioenergy, Volume 18, Issue 6, June 2026.
Switchgrass cultivation sustained biomass production while rapidly improving soil structure and reducing salinity in coastal saline‐alkali soils. These changes reshaped microbial communities through environmental filtering, establishing plant‐soil‐microbe feedbacks that support both bioenergy production and ecological restoration.

A temperate river estuary is a sink for methanotrophs adapted to extremes of pH, temperature and salinity [PDF]

, 2016
River Tyne (UK) estuarine sediments harbour a genetically and functionally diverse community of methane-oxidizing bacteria (methanotrophs), the composition and activity of which were directly influenced by imposed environmental conditions (pH, salinity ...

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

Applied 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
