Reduction in N₂O Emissions and Improvement in Nitrifier and Denitrifier Communities through Bamboo-Biochar-Based Fertilization in Pomelo Orchard Soil

Agronomy, 2023
Farmland soil is an important source of the greenhouse gas nitrous oxide (N2O), and soil nitrification and denitrification are key processes affecting N2O production.

Global biodiversity of aquatic ammonia-oxidizing archaea is partitioned by habitat

Frontiers in Microbiology, 2012
Archaea play an important role in nitrification and are, thus, inextricably linked to the global carbon and nitrogen cycles. Since the initial discovery of an ammonia monooxygenase α-subunit (amoA) gene associated with an archaeal metagenomic fragment ...

Diversity and Abundance of Ammonia-Oxidizing Bacteria and Archaea in a Freshwater Recirculating Aquaculture System

Hayati Journal of Biosciences, 2017
The role of ammonia-oxidizing bacteria and archaea was evaluated using amoA gene in a freshwater recirculating system. Broken earthen pot pieces (BEP) were used as filter bed material.

Impacts of organic and conventional crop management on diversity and activity of free-living nitrogen fixing bacteria and total bacteria are subsidiary to temporal effects [PDF]

, 2012
A three year field study (2007-2009) of the diversity and numbers of the total and metabolically active free-living diazotophic bacteria and total bacterial communities in organic and conventionally managed agricultural soil was conducted at the ...

Ammonia oxidizers in the sea-surface microlayer of a coastal marine inlet. [PDF]

PLoS ONE, 2018
Planktonic archaea are thought to play an important role in ammonia oxidation in marine environments. Data on the distribution, abundance, and diversity of ammonia oxidizers in the coastal sea-surface microlayer (SML) are lacking, despite previous ...

The active functional microbes contribute differently to soil nitrification and denitrification potential under long-term fertilizer regimes in North-East China

Frontiers in Microbiology, 2022
Nitrogen (N) cycling microorganisms mediate soil nitrogen transformation processes, thereby affecting agricultural production and environment quality. However, it is not fully understood how active N-cycling microbial community in soil respond to long ...

Diversity of Archaea and detection of crenarchaeotal amoA genes in the rivers Rhine and Têt [PDF]

Aquatic Microbial Ecology, 2009
Pelagic archaeal phylogenetic diversity and the potential for crenarchaeotal nitrification of Group 1.1a were determined in the rivers Rhine and Tet by 16S rRNA sequencing, catalyzed reported deposition-fluorescence in situ hybridization (CARD–FISH) and quantification of 16S rRNA and functional genes. Euryarchaeota were, for the first time, detected in

Comparison of water availability effect on ammonia-oxidizing bacteria and archaea in microcosms of a Chilean semiarid soil

Frontiers in Microbiology, 2012
Water availability is the main limiting factor in arid soils; however few studies have examined the effects of drying and rewetting on nitrifiers from these environments.
