Effect of exogenous hydrazine on metabolic process of anammox bacteria

Journal of Environmental Management, 2021
The effect of N2H4 (hydrazine) on AnAOB (anaerobic ammonia oxidizing bacteria) metabolic pattern is unknown. Therefore, the main purpose of this paper was to explore the effects of exogenous N2H4 on the SAA (specific anammox activity), characteristics and metabolic pathway of AnAOB.

Partnering of anammox and denitrifying bacteria benefits anammox's recovery from starvation and complete nitrogen removal

Science of The Total Environment, 2022
The cooperative metabolic activity of anammox and denitrifying bacteria could speed up anammox's recovery and reduce nitrate generated from the anammox reaction. In this study, a laboratory-scale model system containing a defined anammox culture AMX and a simultaneous nitrification and denitrification (SND) bacterium - Thauera sp.

Vacuum lyophilization preservation and rejuvenation performance of anammox bacteria

Journal of Bioscience and Bioengineering, 2020
The storage of anaerobic ammonia oxidizing bacteria (anammox) plays an important role in the application of anammox. Glycerol, sodium alginate and DMSO were used as the cryoprotectant, and vacuum lyophilization was used to prepare the anammox bacteria powder.

Individual and combined effect of salinity and nitrite on freshwater Anammox bacteria (FAB).

Water Research, 2020
Anaerobic ammonium oxidation (Anammox) based technology has potential for nitrogen removal from wastewater with high salinity, but both salt and nitrite (a substrate for Anammox) have negative effect on microbial activity.

Potential Growth of Anammox Bacteria under Aerobic Conditions

Environmental Science & Technology
Anammox bacteria are obligate anaerobic bacteria that exist widely in nature with sufficient amounts of dissolved oxygen. However, whether anammox bacteria can grow under aerobic conditions remains unclear. In this study, we found that the production of nitrate in the anammox system under aerobic conditions was significantly higher than that under ...

Anammox bacteria enrichment and denitrification in moving bed biofilm reactors packed with different buoyant carriers: Performances and mechanisms.

Science of the Total Environment, 2020
Anaerobic ammonium oxidation (anammox) is recognized as the most cost-effective process for nitrogen removal from wastewater. In this study, effects of polyethylene plastics, nonwoven fabric, granular activated carbon (GAC) and polyurethane sponge as ...

Temperature dependence for anammox bacteria enriched from freshwater sediments

Journal of Bioscience and Bioengineering, 2012
The anoxic ammonium oxidation (anammox) process has been regarded as an attractive alternative process to treat wastewater containing high ammonium concentrations. By the implementation of anammox process at moderately low temperatures (

Specific and effective detection of anammox bacteria using PCR primers targeting the 16S rRNA gene and functional genes.

Science of the Total Environment, 2020
Anaerobic ammonium-oxidizing (anammox) bacteria play an important role in the nitrogen cycle by coupling ammonium and nitrite to produce dinitrogen gas (N2).
