Rapid achieving partial nitrification in domestic wastewater: Controlling aeration time to selectively enrich ammonium oxidizing bacteria (AOB) after simultaneously eliminating AOB and nitrite oxidizing bacteria (NOB)

Bioresource Technology, 2021
This study developed a novel strategy for rapidly achieving partial nitrification (PN) without additional chemical agents, and infrastructure costs, only by controlling aeration time to selectively enrich ammonium oxidizing bacteria (AOB) after simultaneously eliminating AOB and nitrite oxidizing bacteria (NOB).

Ammonia-Oxidizing Bacteria (AOB): opportunities and applications—a review

Reviews in Environmental Science and Biotechnology, 2018
Recently, partial nitrification has been adopted widely as a first step of both nitrite shunt and deammonification processes towards efficient and economical nitrogen removal from wastewater. Effective partial nitrification relies on stimulating the first step of nitrification while inhibiting the second step and by consequence accumulating ammonia ...

Chemical Acylation of Water‐Soluble Antioxidant of Bamboo Leaves (AOB‐w) and Functional Evaluation of Oil‐Soluble AOB (cAOB‐o)

Journal of Food Science, 2014
Abstract Antioxidant of bamboo leaves (AOB) is a novel natural food antioxidant approved in China since 2004. Natural phenolics contained in the current AOB are usually polyhydroxy derivatives exhibiting hydrophilic character, which has been marked as water‐soluble AOB (AOB‐w).

Effects of ultrasonic treatment on the ammonia-oxidizing bacterial (AOB) growth kinetics

Science of the Total Environment, 2019
Ultrasound has in the past few decades found applications in a variety of disciplines including chemistry, medicine, physics, and to a much less extent microbiology. Our previous studies found that ultrasonic treatment increases the activity of ammonia-oxidizing bacteria (AOB) while suppressing nitrite-oxidizing bacteria (NOB), resulting in beneficial ...

Ultrasonic Treatment Enhanced Ammonia-Oxidizing Bacterial (AOB) Activity for Nitritation Process

open access: yesEnvironmental Science & Technology, 2015
Oxidation of ammonia to nitrite rather than nitrate is critical for nitritation process for wastewater treatment. We proposed a promising approach by using controlled ultrasonic treatment to enhance the activity of ammonia-oxidizing bacteria (AOB) and suppress that of nitrite-oxidizing bacteria (NOB).

AOB Nitrosospira cluster 3a.2 (D11) dominates N2O emissions in fertilised agricultural soils

open access: yesJournal of Environmental Management
Ammonia-oxidation process directly contribute to soil nitrous oxide (N2O) emissions in agricultural soils. However, taxonomy of the key nitrifiers (within ammonia oxidising bacteria (AOB), archaea (AOA) and complete ammonia oxidisers (comammox Nitrospira)) responsible for substantial N2O emissions in agricultural soils is unknown, as is their ...

Effect of ammonia oxidizing bacteria (AOB) kinetics on bioaugmentation

Bioresource Technology, 2012
Bioaugmentation with ammonium oxidizing bacteria (AOB) was tested for 620d. A seeding reactor (R1), two seeded reactors (R2 at 21°C; R3 at 15°C) and an unseeded-control reactor (R4 at 21°C) were operated in parallel (2 ...
