Differential Responses of the Catalytic Efficiency of Ammonia and Nitrite Oxidation to Changes in Temperature

Frontiers in Microbiology, 2022
Microbially mediated nitrification plays an important role in the nitrogen (N) cycle, and rates of activity have been shown to change significantly with temperature.

Comparative physiological and genomic characterization of a novel Nitrobacter vulgaris strain from a nitrate-contaminated subsurface

Applied and Environmental Microbiology
Nitrite-oxidizing bacteria (NOB) represent a crucial node in the global nitrogen cycle. By catalyzing the second step of nitrification—the oxidation of nitrite to nitrate to generate energy for growth—NOB activity controls the fate of nitrite (NO2-) in ...

Autecological Study of the Chemoautotroph Nitrobacter by Immunofluorescence [PDF]

Applied Microbiology, 1974
Fluorescent antibodies (FA) prepared for Nitrobacter agilis and N. winogradskyi were highly reactive in homologous staining. Low-level cross-reactions between the two species were removed by adsorption.

Effects of repeated application of sulfadiazine-contaminated pig manure on the abundance and diversity of ammonia and nitrite oxidizers in the root-rhizosphere complex of pasture plants under field conditions

Frontiers in Microbiology, 2013
In a field experiment, the impact of repeated application of the antibiotic sulfadiazine (SDZ)-contaminated pig manure was assessed on functional microbial communities involved in ammonia and nitrite oxidation in the root-rhizosphere complexes (RRCs) of ...

Detection and counting of Nitrobacter populations in soil by PCR [PDF]

Applied and Environmental Microbiology, 1995
Although the biological conversion of nitrite to nitrate is a well-known process, studies of Nitrobacter populations are hindered by their physiological characteristics. This report describes a new method for detecting and counting Nitrobacter populations in situ with the PCR.

Physiological and Metagenomic Characterizations of the Synergistic Relationships between Ammonia- and Nitrite-Oxidizing Bacteria in Freshwater Nitrification

Frontiers in Microbiology, 2018
Nitrification plays a crucial role in global nitrogen cycling and treatment processes. However, the relationships between the nitrifier guilds of ammonia-oxidizing bacteria (AOB) and nitrite-oxidizing bacteria (NOB) are still poorly understood ...

Isolation and characterization of pure cultures for metabolizing 1,4-dioxane in oligotrophic environments

Water Science and Technology
1,4-Dioxane concentration in most contaminated water is much less than 1 mg/L, which cannot sustain the growth of most reported 1,4-dioxane-metabolizing pure cultures.
