Insight into the structure and metabolic function of iron-rich nanoparticles in anammox bacteria.

Science of the Total Environment, 2021
Anaerobic ammonium-oxidizing (anammox) bacteria are iron abundant and depend heavily on iron-binding proteins. The iron demand of anammox bacteria is relatively large.

Achieving simultaneous nitritation, anammox and denitrification (SNAD) in an integrated fixed-biofilm activated sludge (IFAS) reactor: Quickly culturing self-generated anammox bacteria.

Science of the Total Environment, 2021
In this study, by inoculating nitritation suspended sludge, simultaneous nitritation, anammox and denitrification (SNAD) was established quickly in an integrated fixed-biofilm activated sludge (IFAS) reactor to treat high-ammonia municipal wastewater ...

Multi-omics analysis revealed the selective enrichment of partial denitrifying bacteria for the stable coupling of partial-denitrification and anammox process under the influence of low strength magnetic field.

Water Research, 2023
The microbial consortium involving anaerobic ammonium oxidation (anammox) and partial denitrification (PD), known as PD-anammox, is an emerging energy-efficient and lower carbon nitrogen removal process from wastewater.

Potential Role of the Anammoxosome in the Adaptation of Anammox Bacteria to Salinity Stress.

Environmental Science and Technology
The underlying adaptative mechanisms of anammox bacteria to salt stress are still unclear. The potential role of the anammoxosome in modulating material and energy metabolism in response to salinity stress was investigated in this study.

The coupling of anammox with microalgae-bacteria symbiosis: Nitrogen removal performance and microbial community.

Water Research
The partial nitrification-anammox process for ammonia nitrogen wastewater treatment requires mechanical aeration to provide oxygen, which is not conducive to energy saving.

Inhibitory effects of free ammonia on Anammox bacteria

Biodegradation, 2012
Anammox bacteria can effectively treat high ammonia and nitrite concentrations under anoxic environments. However, the presence of high ammonia and nitrite concentrations may cause free ammonia and nitrous acid inhibition at high pH and temperature environments.

Simultaneous enrichment of denitrifying methanotrophs and anammox bacteria

Applied Microbiology and Biotechnology, 2014
Interaction between denitrifying anaerobic methane oxidation (DAMO) and anaerobic ammonium oxidation (anammox) processes may play an important role in global carbon and nitrogen cycles. In this study, a coculture of denitrifying methanotrophs (DAMO archaea and DAMO bacteria) and anammox bacteria, initially sourced from the environment, was enriched ...

Nitrogen removal performance and characteristics of gel beads immobilized anammox bacteria under different PVA:SA ratios

Water environment research, 2021
Although polyvinyl alcohol and sodium alginate gel (PVA/SA) cell immobilization technology has been successfully applied in anaerobic ammonium oxidation (anammox) processes, there is no comprehensive evaluation of the PVA:SA ratio in PVA/SA gel beads ...

Using Fe(II)/Fe(III) as catalyst to drive a novel anammox process with no need of anammox bacteria.

Water Research, 2020
A novel 'anammox' in the absence of anammox bacteria was confirmed to occur in an anaerobic sludge slurry system, in which Fe(II)/Fe(III) cycle driven by NO2--induced Fe(II) oxidation and subsequent NH4+-induced Fe(III) reduction (Feammox) pushed the ...
