Towards robust partial nitrification in low-ammonia wastewater: Electrospinning nanofiber composite-enhanced hydrogel beads immobilized comammox Nitrospira.

Bioresource Technology
Stable partial nitrification (PN) in low-ammonia wastewater has been a critical challenge, but comammox Nitrospira shows great potential in PN systems due to unique physiological characteristics.

Phylum BVIII. Nitrospirae phy. nov.

2001
The phylum Nitrospirae is based mainly on phylogenetic grounds. At present, it consists of a single class, order, and family of Bacteria and environtaxa that branch deeply in the major reference trees; member taxa consistently group together. Gram-negative, curved, vibrioid or spiral-shaped cells.

Comammox Nitrospira Species Dominate in an Efficient Partial Nitrification-Anammox Bioreactor for Treating Ammonium at Low Loadings.

Environmental Science and Technology, 2021
Bacteria capable of complete ammonia oxidation (comammox) are widespread and contribute to nitrification in wastewater treatment facilities. However, their roles in partial nitrification-anaerobic ammonium oxidation (anammox) systems remain unclear.

Nitrite concentration influences the population structure of Nitrospira ‐like bacteria

Environmental Microbiology, 2006
Summary Chemolithoautotrophic nitrite oxidizers of the genus Nitrospira are a monophyletic but diverse group of organisms, are widely distributed in many natural habitats, and play a key role in nitrogen elimination during biological wastewater treatment.

Nitrospira as versatile nitrifiers: Taxonomy, ecophysiology, genome characteristics, growth, and metabolic diversity

Journal of Basic Microbiology, 2021
The global nitrogen cycle is of paramount significance as it affects important processes like primary productivity and decomposition. Nitrification, the oxidation of ammonia to nitrate via nitrite, is a key process in the nitrogen cycle.
