Classification of eight new species of ammonia-oxidizing bacteria: Nitrosomonas communis sp. nov., Nitrosomonas ureae sp. nov., Nitrosomonas aestuarii sp. nov., Nitrosomonas marina sp. nov., Nitrosomonas nitrosa sp. nov., Nitrosomonas eutropha sp. nov., Nitrosomonas oligotropha sp. nov. and Nitrosomonas halophila sp. nov. [PDF]

open access: yesJournal of General Microbiology, 1991
Summary: A total of 13 species of lithotrophic ammonia-oxidizing bacteria assigned to the genus Nitrosomonas were characterized. DNA homologies, G + C content of the DNA, shape and ultrastructure of the cells, salt requirements, ammonia tolerance, utilization of urea as ammonia source, and whole-cell protein patterns were analysed.

Ecophysiology and Comparative Genomics of Nitrosomonas mobilis Ms1 Isolated from Autotrophic Nitrifying Granules of Wastewater Treatment Bioreactor

open access: yesFrontiers in Microbiology, 2016
Ammonia-oxidizing bacteria (AOB), which oxidize ammonia to nitrite in the first step of nitrification, play an important role in biological wastewater treatment systems.

Diversity and characterization of the ammonia-oxidizing bacteria responsible for nitrification in tea field soils [PDF]

open access: yesScientific Reports
Ammonia-oxidizing bacteria (AOB), ammonia-oxidizing archaea (AOA), and comammox Nitrospira have been considered to coexist in acidic soils, oxidizing ammonia within their respective niches.

Inhibition of Targeted Bacterial Growth Using MazF-Expressing Phagemids: A Novel Therapeutic Approach Based on Endoribonuclease Toxin Molecules. [PDF]

open access: yesMicrobiol Immunol
ABSTRACT The extensive and indiscriminate use of antibiotics, which are intended to halt bacterial growth or eliminate them, has unintentionally given rise to antimicrobial resistance (AMR), which is a critical threat to global health. In the pursuit of alternative solutions, researchers have focused on type II toxin–antitoxin systems prevalent within ...

Comparative enrichment of complete ammonium oxidation bacteria in floccular sludge reactors: Sequencing batch reactor vs. continuous stirred tank reactor [PDF]

open access: yesWater Research X
This study attempted to compare the enrichment of complete ammonium oxidation (comammox) bacteria, which are affiliated with Nitrospira and not able to generate nitrous oxide (N2O, a potent greenhouse gas) through biological pathways, in two commonly ...

Analysis of 16S rRNA gene variability in soil nitrifying bacteria of the genus Nitrosomonas

open access: yesBIO Web of Conferences, 2021
The main goal of the work was to assess variability of 16S rRNA gene sequence within the nitrifying bacterial genus Nitrosomonas to find specific sequences for its detection.

Biochar Addition Inhibits Nitrification by Shifting Community Structure of Ammonia-Oxidizing Microorganisms in Salt-Affected Irrigation-Silting Soil

open access: yesMicroorganisms, 2022
Biochar has been widely recognized as an effective and eco-friendly ameliorant for saline soils, but information about the mechanism of how biochar influences nitrification in salt-affected agroecosystem remains fragmented.

Insights into activated sludge/Chlorella consortia under dark condition compared with light condition

open access: yesWater Science and Technology, 2022
Bacteria–algae consortia in the light bring the benefit of O2 production and CO2 reduction for wastewater treatment, while the bottleneck for application is how it behaves in the dark.

Preservation of Nitrosomonas [PDF]

open access: yesNature, 1957
IN a communication under this title in Nature of April 13, Mr. K. Gundersen concludes that preservation under paraffin oil seems to be more promising than any other method used. He was evidently not aware that I mentioned in an article in Nature of February 12, 1955, the use of mineral oil for the maintenance of crude and pure cultures of nitrifying ...

Small Sample Stress: Probing Oxygen-Deprived Ammonia-Oxidizing Bacteria with Raman Spectroscopy In Vivo

open access: yesMicroorganisms, 2020
The stress response of ammonia-oxidizing bacteria (AOB) to oxygen deprivation limits AOB growth and leads to different nitrification pathways that cause the release of greenhouse gases.
