Cometabolism of trihalomethanes by Nitrosomonas europaea. [PDF]

Appl Environ Microbiol, 2005
ABSTRACT The ammonia-oxidizing bacterium Nitrosomonas europaea (ATCC 19718) was shown to degrade low concentrations (50 to 800 μg/liter) of the four trihalomethanes (trichloromethane [TCM], or chloroform; bromodichloromethane [BDCM]; dibromochloromethane [DBCM]; and tribromomethane [TBM], or bromoform ...

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

Microorganisms, 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.

Evidences towards deciphering the mode of action of dimethylpyrazole-based nitrification inhibitors in soil and pure cultures of Nitrosomonas europaea

Chemical and Biological Technologies in Agriculture, 2022
Background Agriculture relies on the intensive use of synthetic nitrogen (N) fertilizers to maximize crop yields, which has led to the transformation of agricultural soils into high-nitrifying environments.

Metabolic and Proteomic Responses to Salinity in Synthetic Nitrifying Communities of Nitrosomonas spp. and Nitrobacter spp.

Frontiers in Microbiology, 2018
Typically, nitrification is a two-stage microbial process and is key in wastewater treatment and nutrient recovery from waste streams. Changes in salinity represent a major stress factor that can trigger response mechanisms, impacting the activity and ...

Growth ofNitrosomonas europaeaon hydroxylamine [PDF]

FEMS Microbiology Letters, 1995
Hydroxylamine is an intermediate in the oxidation of ammonia to nitrite, but until now it has not been possible to grow Nitrosomonas europaea on hydroxylamine. This study demonstrates that cells of N. europaea are capable of growing mixotrophically on ammonia and hydroxylamine. The molar growth yield on hydroxylamine (4.74 g mol−1 at a growth rate of 0.

Gradient microfluidics enables rapid bacterial growth inhibition testing [PDF]

, 2014
Bacterial growth inhibition tests have become a standard measure of the adverse effects of inhibitors for a wide range of applications, such as toxicity testing in the medical and environmental sciences. However, conventional well-plate formats for these

Cometabolism of 17α-ethynylestradiol by nitrifying bacteria depends on reducing power availability and leads to elevated nitric oxide formation

Environment International, 2021
17α-ethynylestradiol (EE2) is a priority emerging contaminant (EC) in diverse environments that can be cometabolized by ammonia oxidizing bacteria (AOB). However, its transformation kinetics and the underlying molecular mechanism are unclear.
