Effect of Nitric Oxide on Anammox Bacteria [PDF]

open access: yesApplied and Environmental Microbiology, 2010
ABSTRACT The effects of nitrogen oxides on anammox bacteria are not well known. Therefore, anammox bacteria were exposed to 3,500 ppm nitric oxide (NO) in the gas phase. The anammox bacteria were not inhibited by the high NO concentration but rather used it to oxidize additional ammonium to dinitrogen gas under conditions relevant to ...

Anaerobic Ammonium Oxidation in Acidic Red Soils

open access: yesFrontiers in Microbiology, 2018
Anaerobic ammonium oxidation (anammox) has been proven to be an important nitrogen removal process in terrestrial ecosystems, particularly paddy soils. However, the contribution of anammox in acidic red soils to nitrogen loss has not been well-documented

Metabolic acclimation of anammox consortia to decreased temperature

open access: yesEnvironment International, 2020
Widespread application of anammox process has been primarily limited to the high sensitivity of anammox consortia to fluctuations of temperature. However, the metabolic acclimation of anammox consortia to decreased temperature remains unclear, which is ...

Nitrogen removal in marine environments: recent findings and future research challenges [PDF]

open access: yes, 2005
Respiratory reduction of nitrate (denitrification) is recognized as the most important process converting biologically available (fixed) nitrogen to N2. In current N cycle models, a major proportion of global marine denitrification (50–70%) is assumed to

Increased salinity improves the thermotolerance of mesophilic nitrification [PDF]

open access: yes, 2014
Nitrification is a well-studied and established process to treat ammonia in wastewater. Although thermophilic nitrification could avoid cooling costs for the treatment of warm wastewaters, applications above 40 A degrees C remain a significant challenge.

Effects of antimicrobials in anammox mediated systems: critical review

open access: yesWater Science and Technology, 2022
Anammox-mediated systems are thought to be cost-effective and efficient technologies for removing nitrogen from wastewater by converting nitrite and ammonium into dinitrogen gas.

Extreme enrichment in atmospheric 15N15N. [PDF]

open access: yes, 2017
Molecular nitrogen (N2) comprises three-quarters of Earth's atmosphere and significant portions of other planetary atmospheres. We report a 19 per mil (‰) excess of 15N15N in air relative to a random distribution of nitrogen isotopes, an enrichment that ...

Anoxic nitrification in marine sediments [PDF]

open access: yes, 2004
Nitrate peaks are found in pore-water profiles in marine sediments at depths considerably below the conventional zone of oxic nitrification. These have been interpreted to represent nonsteady- state effects produced by the activity of nitrifying ...

Characterization of a Microbial Community in an Anammox Process Using Stored Anammox Sludge [PDF]

open access: yesWater, 2017
This study investigated a rapid start-up anaerobic ammonium oxidation (Anammox) process by inoculation with stored Anammox sludge and characterized the associated microbial communities. The Anammox process took only 43 days to start. A high nitrogen removal rate of 1.13 kg N m−3 d−1 and a nitrogen loading rate of 1.28 kg N m−3 d−1 were achieved.
