A novel strategy combining aerobic starvation and free ammonia (FA) was proposed to achieve partial nitrification (PN). The impact of the combined strategy on nitrifying bacteria was explored in a 200-day experiment. The effluent concentration of ammonia

The ammonia oxidation process driven by microorganisms is an essential source of nitrous oxide (N2O) and nitric oxide (NO) emissions. However, few evaluations have been performed on the changes in the community structure and abundance of soil ammonia ...

Archaea, 2018 An increase in the number of publications in recent years indicates that besides ammonia-oxidizing bacteria (AOB), ammonia-oxidizing archaea (AOA) may play an important role in nitrogen removal from wastewater, gaining wide attention in the wastewater ...

The controversial arguments on the true substrate in nitritation kinetics might be due to the cells' dual substrate-transport system. Our experiments revealed that, under ammonia-rich environments, it diffused into the membrane (ammonia was the direct ...

Unravelling the reasons for disproportion in the ratio of AOB and NOB in aerobic granular sludge
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 ...

Oxidative Stress and Antioxidant Biofactor (AOB®)
1997Antioxidant biofactor (AOB®) is an unique processed grain food obtained from soybean, wheat, rice germ, rice bran, tear grass, green tea, sesame, citron, green leaves extracts and malted rice. These ingredients were degraded to low molecular weight compounds by roast and fermentation with Aspergilus oryzae (Fig. 1).
