Unravelling the reasons for disproportion in the ratio of AOB and NOB in aerobic granular sludge [PDF]

open access: yesApplied 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

Models for nitrification process design: one or two AOB populations? [PDF]

open access: yesWater Science and Technology, 2010
Models for engineering design of nitrifying systems use one ammonia oxidizer biomass (AOB) state variable. A simple extension using two AOB populations allows a more accurate prediction of nitrification systems at switching process environments. These two AOB subpopulations are characterized by two different sets of kinetic parameters.

Transposition and Intermingling of Galphai2 and Galphao afferences into single vomeronasal glomeruli in the Madagascan lesser Tenrec Echinops telfairi. [PDF]

open access: yesPLoS ONE, 2009
The vomeronasal system (VNS) mediates pheromonal communication in mammals. From the vomeronasal organ, two populations of sensory neurons, expressing either Galphai2 or Galphao proteins, send projections that end in glomeruli distributed either at the ...

The AOB subdivisions in rats respond differently to social stimulation [PDF]

open access: yesProcedia - Social and Behavioral Sciences, 2012
AbstractThe animal's ability to recognise and differentiate between familiar and unfamiliar conspecifics, plays a crucial role in their social behaviour. To study the neural mechanisms underlying individual recognition, the expression patterns of the Immediate Early Genes c-Fos, Egr.1, and Arc were investigated immunocytochemically in the brains of ...

Recovering partial nitritation in a PN/A system during mainstream wastewater treatment by reviving AOB activity after thoroughly inhibiting AOB and NOB with free nitrous acid

open access: yesEnvironment 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 ...

Consumption of ammonia-nitrogen by aob in immobilized batch culture [PDF]

open access: yesJournal of Fundamental and Applied Sciences, 2018
This study investigated the performance of bio-filters immobilized nitrifying bacteria, ammonia oxidizing bacteria (AOB) and nitrite oxidizing bacteria (NOB). In particular, it wasto assess the consumption of ammonia-nitrogen (NH3-N) by the AOB. The experiment wasconducted in a one litre reactor.The reactor consisted of bio-filters with NH3-N as ...

AOB - Acoustic Oceanographic Buoy: concept and feasibility [PDF]

open access: yes, 2006
The AOB - Acoustic Oceanographic Buoy is the single node of a network of “smart” buoys for acoustic surveillance, Rapid Environmental Assessment (REA) and underwater communications. The AOB is a lightweight surface buoy with a vertical array of acoustic receivers and temperature sensors to be air dropped or hand deployed from a small boat. The received

Biological nitrification inhibition by rice root exudates in two different soils of Uruguay

open access: yesActa Agriculturae Scandinavica. Section B, Soil and Plant Science, 2021
Rice root exudates can control nitrification by releasing biological nitrification inhibitors (BNIs), reducing nitrogen losses in agricultural soils. However, the inhibitory effect on nitrification and the abundance of ammonia oxidisers in different soil
