Characterization of the First “
mBio, 2018 Nitrification is a key process of the biogeochemical nitrogen cycle and of biological wastewater treatment. The second step, nitrite oxidation to nitrate, is catalyzed by phylogenetically diverse, chemolithoautotrophic nitrite-oxidizing bacteria (NOB ...

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

Evolutionary relationships among ammonia- and nitrite-oxidizing bacteria
Journal of Bacteriology, 1994 Comparative 16S rRNA sequencing was used to evaluate phylogenetic relationships among selected strains of ammonia- and nitrite-oxidizing bacteria. All characterized strains were shown to be affiliated with the proteobacteria. The study extended recent 16S rRNA-based studies of phylogenetic diversity among nitrifiers by the comparison of eight strains ...

Kinetic plasticity of nitrite-oxidizing bacteria containing cytoplasmic nitrite oxidoreductase [PDF]
The ISME JournalAbstract Nitrite-oxidizing bacteria (NOB) use either periplasmic (pNXR) or cytoplasmic (cNXR) nitrite oxidoreductase to oxidize nitrite, and this distinction influences nitrite affinity and energy yield. cNXR-containing NOB have historically been considered low-affinity, copiotrophic nitrifiers adapted to high nitrite and neutral pH ...

Nitrite-oxidizing bacteria adapted to low-oxygen conditions dominate nitrite oxidation in marine oxygen minimum zones [PDF]
The ISME JournalAbstract Nitrite is a central molecule in the nitrogen cycle because nitrite oxidation to nitrate (an aerobic process) retains fixed nitrogen in a system and its reduction to dinitrogen gas (anaerobic) reduces the fixed nitrogen inventory.

Application of hierarchical oligonucleotide primer extension (HOPE) to assess relative abundances of ammonia- and nitrite-oxidizing bacteria. [PDF]
BMC Microbiol, 2017 Background Establishing an optimal proportion of nitrifying microbial populations, including ammonia-oxidizing bacteria (AOB), nitrite-oxidizing bacteria (NOB), complete nitrite oxidizers (comammox) and ammonia-oxidizing archaea (AOA), is important for ...

Comparison of Oxidation Kinetics of Nitrite-Oxidizing Bacteria: Nitrite Availability as a Key Factor in Niche Differentiation [PDF]
Applied and Environmental Microbiology, 2015 ABSTRACT Nitrification has an immense impact on nitrogen cycling in natural ecosystems and in wastewater treatment plants. Mathematical models function as tools to capture the complexity of these biological systems, but kinetic parameters especially of nitrite-oxidizing bacteria (NOB) are lacking because of a limited number of ...
