Microbial community composition of transiently wetted Antarctic Dry Valley soils [PDF]

, 2015
During the summer months, wet (hyporheic) soils associated with ephemeral streams and lake edges in the Antarctic Dry Valleys (DVs) become hotspots of biological activity and are hypothesized to be an important source of carbon and nitrogen for arid DV ...

Niche Differentiation of Comammox Nitrospira in the Mudflat and Reclaimed Agricultural Soils Along the North Branch of Yangtze River Estuary

Frontiers in Microbiology, 2021
The discovery of complete ammonia oxidation (comammox), oxidizing ammonia to nitrate via nitrite in a single organism, has redefined the traditional recognition of the two-step nitrification driven by two functional groups (ammonia-oxidizing and nitrite ...

Genomic profiling ofNitrospiraspecies reveals ecological success of comammoxNitrospira [PDF]

, 2019
AbstractNitrification was long thought to consist in the stepwise oxidation of ammonia to nitrite and of nitrite to nitrate by ammonia oxidizing and nitrite oxidizing microorganisms, respectively. Recently, single microorganisms capable of complete ammonia to nitrate oxidation (comammox) were identified in theNitrospiragenus.

Microbial community changes induced by Managed Aquifer Recharge activities: linking hydrogeological and biological processes [PDF]

, 2019
Managed Aquifer Recharge (MAR) is a technique used worldwide to increase the availability of water resources. We study how MAR modifies microbial ecosystems and its implications for enhancing biodegradation processes to eventually improve groundwater ...

Genome-Enabled Insights into the Ecophysiology of the Comammox Bacterium “Candidatus Nitrospira nitrosa”

mSystems, 2017
The recently discovered comammox bacteria have the potential to completely oxidize ammonia to nitrate. These microorganisms are part of the Nitrospira genus and are present in a variety of environments, including biological nutrient removal (BNR) systems.

The impact of fertilization on ammonia-oxidizing bacteria and comammox Nitrospira communities and the subsequent effect on N2O emission and maize yield in a semi-arid region

Frontiers in Microbiology, 2023
The control of nitrous oxide (N2O) emissions through nitrification and the optimization of maize yield are important in agricultural systems. However, within the semi-arid region, the impact of fertilization on the function of nitrification communities ...

Increased salinity improves the thermotolerance of mesophilic nitrification [PDF]

, 2014
Nitrification is a well-studied and established process to treat ammonia in wastewater. Although thermophilic nitrification could avoid cooling costs for the treatment of warm wastewaters, applications above 40 A degrees C remain a significant challenge.

Differential responses of canonical nitrifiers and comammox Nitrospira to long-term fertilization in an Alfisol of Northeast China

Frontiers in Microbiology, 2023
The newly identified complete ammonia oxidizer (comammox) that converts ammonia directly into nitrate has redefined the long-held paradigm of two-step nitrification mediated by two distinct groups of nitrifiers.

Microbial diversity in the thermal springs within Hot Springs National Park [PDF]

, 2018
The thermal water systems of Hot Springs National Park (HSNP) in Hot Springs, Arkansas exist in relative isolation from other North American thermal systems. The HSNP waters could therefore serve as a unique center of thermophilic microbial biodiversity.

A novelNitrospiralineage isolated from activated sludge using elevated temperatures [PDF]

FEMS Microbiology Letters, 2023
AbstractThe genus Nitrospira represents the dominant nitrite-oxidizing clade in most wastewater treatment plants (WWTPs) globally, and several Nitrospira strains have been isolated from activated sludge. Using a pre-enrichment strategy with alternating nitrifying and denitrifying conditions, followed by incubation at elevated temperatures, we isolated ...
