Unravelling the reasons for disproportion in the ratio of AOB and NOB in aerobic granular sludge [PDF]
Applied Microbiology and Biotechnology, 2012 In this study, we analysed the nitrifying microbial community (ammonium-oxidizing bacteria (AOB) and nitrite-oxidizing bacteria (NOB)) within three different aerobic granular sludge treatment systems as well as within one flocculent sludge system. Granular samples were taken from one pilot plant run on municipal wastewater as well as from two lab-scale

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 ...

Environment International, 2020 Starting up or recovering partial nitritation is a major challenge for achieving or maintaining stable partial nitritation/anammox (PN/A) during mainstream wastewater treatment. This study presents a novel strategy for recovering the nitrite pathway by selectively reviving ammonium oxidizing bacteria (AOB) after thoroughly inhibiting AOB and nitrite ...

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).

Correlation between nitrite accumulation and the concentration of AOB in a nitritation reactor
Environmental Earth Sciences, 2014 Nitritation is an innovative biological nitrogen removal method in wastewater, and it has the advantages of energy and economy. The correlation between a nitrite conversion rate and the gene copy numbers of ammonia oxidizing bacteria (AOB) in a ...

Ammonia-Oxidizing Bacteria (AOB): opportunities and applications—a review
Reviews in Environmental Science and Biotechnology, 2018Recently, 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 ...

Effect of ammonia oxidizing bacteria (AOB) kinetics on bioaugmentation
Bioresource Technology, 2012Bioaugmentation 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 ...

Kinetic analysis on the two-step processes of AOB and NOB in aerobic nitrifying granules
Applied Microbiology and Biotechnology, 2009 Complete granulation of nitrifying sludge was achieved in a sequencing batch reactor. For the granular sludge, batch experiments were conducted to characterize the kinetic features of ammonia oxidizers (AOB) and nitrite oxidizers (NOB) in the granules ...

Spatial distribution and abundances of ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB) in mangrove sediments [PDF]
Applied Microbiology and Biotechnology, 2010 We investigated the diversity, spatial distribution, and abundances of ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB) in sediment samples of different depths collected from a transect with different distances to mangrove forest in ...
