Comammox Nitrospira act as key bacteria in weakly acidic soil via potential cobalamin sharing [PDF]

iMeta
The discovery of comammox Nitrospira in low pH environments has reshaped the ammonia oxidation process in acidic settings, providing a plausible explanation for the higher nitrification rates observed in weakly acidic soils.

Niche differentiation among comammox (Nitrospira inopinata) and other metabolically distinct nitrifiers [PDF]

Frontiers in Microbiology, 2022
Due to global change, increasing nutrient input to ecosystems dramatically affects the nitrogen cycle, especially the nitrification process. Nitrifiers including ammonia-oxidizing archaea (AOAs), ammonia-oxidizing bacteria (AOBs), nitrite-oxidizing ...

Unusual Plastoquinones in Non-Phototrophic Nitrifying Bacteria. [PDF]

Environ Microbiol Rep
Isoprenoid quinones are important compounds in most organisms. They are essential in electron and proton transport in respiratory and photosynthetic electron transport chains, and additional functions include oxidative stress defence.

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

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 ...

Unraveling the important role of comammox Nitrospira to nitrification in the coastal aquaculture system [PDF]

Frontiers in Microbiology
Increasing nitrogen (N) input to coastal ecosystems poses a serious environmental threat. It is important to understand the responses and feedback of N removal microbial communities, particularly nitrifiers including the newly recognized complete ammonia-

Enrichment of Comammox and Nitrite-Oxidizing Nitrospira From Acidic Soils [PDF]

Frontiers in Microbiology, 2020
In agricultural soils fertilized with a high amount of ammonium nitrogen, the pH decreases because of the oxidation of ammonia by nitrifiers. Molecular-based analyses have revealed that members of the genus Nitrospira dominate over other nitrifiers in ...

Nitrogen Kinetic Isotope Effects of Nitrification by the Complete Ammonia Oxidizer Nitrospira inopinata [PDF]

mSphere, 2021
Analysis of nitrogen isotope fractionation effects is useful for tracing biogeochemical nitrogen cycle processes. Nitrification can cause large nitrogen isotope effects through the enzymatic oxidation of ammonia (NH3) via nitrite (NO2−) to nitrate (NO3−)

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

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.

Soil moisture is a primary driver of comammox Nitrospira abundance in New Zealand soils [PDF]

SSRN Electronic Journal, 2022
The objectives of this study were to investigate the abundance and community composition of comammox Nitrospira under: (i) pasture-based dairy farms from different regions, and (ii) different land uses from the same region and soil type.
