Preservation of Nitrosomonas [PDF]
Nature, 1957 IT is well known that the isolation of Nitrosomonas in pure culture is rather difficult; another problem is how the pure cultures can be successfully preserved. Nitrosomonas seems to be more frail than most other bacteria when in pure culture, and unfortunately the majority of strains isolated during past years have been lost.

Effect of Organic Compounds on Nitrosomonas [PDF]
Nature, 1950 THE growth of nitrifying bacteria (Nitrosomonas and Nitrobacter) is usually inhibited by comparatively low concentrations of soluble organic substances, particularly amino-compounds1–3. A rather exceptional resistance was shown by a strain of Nitrosomonas that was isolated from farmyard manure and in other respects appeared typical (oval rods, motile ...

Isolation of Nitrosomonas from Rothamsted Soil [PDF]
Nature, 1949 SINCE Nitrosomonas, a bacterium which oxidizes ammonia to nitrite, was discovered by Warington1 and the Franklands2 and first isolated by Winogradsky3, nearly sixty years ago, there are only a few records of its isolation in pure culture.

Diversity and characterization of the ammonia-oxidizing bacteria responsible for nitrification in tea field soils [PDF]
Scientific ReportsAmmonia-oxidizing bacteria (AOB), ammonia-oxidizing archaea (AOA), and comammox Nitrospira have been considered to coexist in acidic soils, oxidizing ammonia within their respective niches.

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

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]
Journal 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.
