Nutrient-Limited Enrichments of Nitrifiers From Soil Yield Consortia of Nitrosocosmicus-Affiliated AOA and Nitrospira-Affiliated NOB

open access: yesFrontiers in Microbiology, 2021
The discovery of ammonia-oxidizing archaea (AOA) and complete ammonia-oxidizing (comammox) bacteria widespread in terrestrial ecosystems indicates an important role of these organisms in terrestrial nitrification.

Nitrospira bacteria in paddy soil reduced by biochar application [PDF]

open access: yesAgrosystems, Geosciences & Environment, 2020
AbstractBiochar application can depress nitrification in paddy soils, but the microbiological mechanisms involved in this process are not clearly understood. This study was conducted to test the hypothesis that biochar may affect nitrification bacteria in paddy soils.

Application of COMPOCHIP Microarray to Investigate the Bacterial Communities of Different Composts [PDF]

open access: yes, 2009
A microarray spotted with 369 different 16S rRNA gene probes specific to microorganisms involved in the degradation process of organic waste during composting was developed. The microarray was tested with pure cultures, and of the 30,258 individual probe-

Investigating the Chemolithoautotrophic and Formate Metabolism of Nitrospira moscoviensis by Constraint-Based Metabolic Modeling and 13C-Tracer Analysis

open access: yesmSystems, 2021
Nitrite-oxidizing bacteria belonging to the genus Nitrospira mediate a key step in nitrification and play important roles in the biogeochemical nitrogen cycle and wastewater treatment.

Niche specialization of comammox Nitrospira in terrestrial ecosystems: Oligotrophic or copiotrophic?

open access: yesCritical reviews in environmental science and technology, 2022
The discovery of complete ammonia oxidizers, comammox Nitrospira, represents a breakthrough in the history of nitrification research. Nitrospira inopinata, which was obtained from an aquatic ecosystem, is the only pure comammox bacterial isolate reported

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

open access: yesFrontiers 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 bacteria (NOBs), and recently discovered complete ammonia oxidizers (comammoxs) perform nitrification ...

Nitrification mainly driven by ammonia-oxidizing bacteria and nitrite-oxidizing bacteria in an anammox-inoculated wastewater treatment system

open access: yesAMB Express, 2021
Anaerobic ammonium oxidation (anammox) process has been acknowledged as an environmentally friendly and time-saving technique capable of achieving efficient nitrogen removal.

Metagenomic analysis of rapid gravity sand filter microbial communities suggests novel physiology of Nitrospira spp [PDF]

open access: yes, 2016
Rapid gravity sand filtration is a drinking water production technology widely used around the world. Microbially catalyzed processes dominate the oxidative transformation of ammonia, reduced manganese and iron, methane and hydrogen sulfide, which may ...

Nitrite-Oxidizing Bacteria Community Composition and Diversity Are Influenced by Fertilizer Regimes, but Are Independent of the Soil Aggregate in Acidic Subtropical Red Soil

open access: yesFrontiers in Microbiology, 2018
Nitrification is the two-step aerobic oxidation of ammonia to nitrate via nitrite in the nitrogen-cycle on earth. However, very limited information is available on how fertilizer regimes affect the distribution of nitrite oxidizers, which are involved in

Effect of the dilution rate on microbial competition: r-strategist can win over k-strategist at low substrate concentration. [PDF]

open access: yesPLoS ONE, 2017
The conditions present in both in vitro and in vivo ecosystems determine the microbial population harbouring it. One commonly accepted theory is that a species with a high substrate affinity and low growth rate (k-strategist) will win the competition ...
