“…As we understand the processes now, there is no, or at least lower, N 2 O emission via the anammox or ANME coupled to denitrification pathway, which is another great advantage over conventional nitrification and denitrification (Kampschreur et al 2008;Zhu et al 2008). Therefore, the ratio of anammox to conventional nitrification/denitrification could influence net fluxes of these trace gases, with ramifications for global warming and the catalytic destruction of ozone in the stratosphere.…”

Anaerobic ammonium oxidation (anammox) and anaerobic methane oxidation (ANME coupled to denitrification) with nitrite as electron acceptor are two of the most recent discoveries in the microbial nitrogen cycle. Currently the anammox process has been relatively well investigated in a number of natural and man-made ecosystems, while ANME coupled to denitrification has only been observed in a limited number of freshwater ecosystems. The ubiquitous presence of anammox bacteria in marine ecosystems has changed our knowledge of the global nitrogen cycle. Up to 50% of N 2 production in marine sediments and oxygendepleted zones may be attributed to anammox bacteria. However, there are only few indications of anammox in natural and constructed freshwater wetlands. In this paper, the potential role of anammox and denitrifying methanotrophic bacteria in natural and artificial wetlands is discussed in relation to global warming. The focus of the review is to explore and analyze if suitable environmental conditions exist for anammox and denitrifying methanotrophic bacteria in nitrogen-rich freshwater wetlands.

“…In this context, it is worth noting that N 2 O emissions are mainly related to the processes associated with the biological nitrogen removal (Kampschreur et al, 2009). N 2 O can be produced both during nitrification and/or denitrification processes (Kampschreur et al, 2008;Law et al, 2012b).…”

“…The PN-anammox process is applicable to reject water (Desloover et al, 2011;Kampschreur et al, 2008;2009a;Joss et al, 2009;Okabe et al, 2011), landfill leachate (Wang et al, 2010), and wastewater from semiconductor factory (Tokutomi et al, 2011). N 2 O emission from PN-anammox processes, especially from the PN process, has been reported (Desloover et al, 2011;Kampschreur et al, 2008;Okabe et al, 2011).…”

Source identification of nitrous oxide on autotrophic partial nitrification in a granular sludge reactor

Emission of nitrous oxide (N 2 O) during biological wastewater treatment is of growing concern since N 2 O is a major stratospheric ozone-depleting substance and an important greenhouse gas. The emission of N 2 O from a lab-scale granular sequencing batch reactor (SBR) for partial nitrification (PN) treating synthetic wastewater without organic carbon was therefore determined in this study, because PN process is known to produce more N 2 O than conventional nitrification processes. The average N 2 O emission rate from the SBR was 0.32 ± 0.17 mg-N L -1 h -1 , corresponding to the average emission of N 2 O of 0.8 ± 0.4% of the incoming nitrogen load (1.5 ± 0.8% of the converted NH 4 + ). Analysis of dynamic concentration profiles during one cycle of the SBR operation demonstrated that N 2 O concentration in off-gas was the highest just after starting aeration whereas N 2 O concentration in effluent was gradually increased in the initial 40 min of the aeration period and was decreased thereafter. Isotopomer analysis was conducted to identify the main N 2 O production pathway in the reactor during one cycle. The hydroxylamine (NH 2 OH) oxidation pathway accounted for 65% of the total N 2 O production in the initial phase during one cycle, whereas contribution of the NO 2 -reduction pathway to N 2 O production was comparable with that of the NH 2 OH oxidation pathway in the latter phase. In addition, 3 spatial distributions of bacteria and their activities in single microbial granules taken from the reactor were determined with microsensors and by in situ hybridization. Partial nitrification occurred mainly in the oxic surface layer of the granules and ammonia-oxidizing bacteria were abundant in this layer. N 2 O production was also found mainly in the oxic surface layer. Based on these results, although N 2 O was produced mainly via NH 2 OH oxidation pathway in the autotrophic partial nitrification reactor, N 2 O production mechanisms were complex and could involve multiple N 2 O production pathways.
