Preservation of Nitrosomonas [PDF]

open access: yesNature, 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.

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.

Isolation of Nitrosomonas from Rothamsted Soil [PDF]

open access: yesNature, 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.

Effect of Organic Compounds on Nitrosomonas [PDF]

open access: yesNature, 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 ...

Light induced Nitrosomonas inhibition

Water Research, 1987
The purpose of this study was to evaluate and verify the impact of light exposure on an enriched Nitrosomonas culture. Resting cells maintained under aerobic conditions without an exogenous ammonium-nitrogen source were fully inhibited within a 10 min period of ambient light contact (i.e. fluorescent and indirect natural room light).

Chemoorganoheterotrophic Growth of Nitrosomonas europaea and Nitrosomonas eutropha

Current Microbiology, 2009
The ammonia oxidizers Nitrosomonas europaea and Nitrosomonas eutropha are able to grow chemoorganotrophically under anoxic conditions with pyruvate, lactate, acetate, serine, succinate, alpha-ketoglutarate, or fructose as substrate and nitrite as terminal electron acceptor.

Anaerobic metabolism of Nitrosomonas europaea

Archives of Microbiology, 1992
Nitrosomonas europaea is capable of maintaining an anaerobic metabolism, using pyruvate as an electron donor and nitrite as an electron acceptor; utilization of nitrite depends upon supply of both pyruvate and ammonia. The role of ammonia in this reaction was not determined.

Ethylene oxidation by Nitrosomonas europaea

Archives of Microbiology, 1984
Incubation of whole cells of the nitrifying bacterium Nitrosomonas europaea with ethylene led to the formation of ethylene oxide. Ethylene oxide production was prevented by inhibitors of ammonium ion oxidation, and showed properties implying that ethylene is a substrate for the ammonia oxidising enzyme, ammonia monooxygenase.

Exploring nitrifier denitrification in Nitrosomonas communis and Nitrosomonas europaea through physiology and proteomic analysis

2023
The current understanding of how ammonia oxidizing bacteria (AOB) produce the potent greenhouse gas nitrous oxide is incomplete and inaccurate since most studies are focused on the model organism for the group, Nitrosomonas europaea, which does not represent the physiological diversity of AOB.
