“…The nitrogen removal rate was six to 31 times higher than the values reported in other studies that used a column reactor fed deep sea water containing minerals (20), a column reactor fed a synthetic salt-based medium (12), and sequencing batch reactors fed a sea salt-based medium (35). The high nitrogen removal rate in this study was attributed to the short HRT.…”

“…Since neither marine anammox bacteria nor wastewater anammox bacteria have been isolated in pure cultures, enrichment of marine anammox bacteria is valuable for understanding a microbial community in association with the marine anammox reaction and in situ activities of marine anammox bacteria and for application to the treatment of industrial wastewater containing high levels of ammonium and salt. Although "Candidatus Scalindua" is dominant in marine environments, only a few "Candidatus Scalindua" species have been enriched from sea sediment (12,20,35). Furthermore, the cultures showed a low population density (67-90% of total bacteria) and/or low conversion rates (0.07-0.35 g L −1 day −1 ) after long periods of enrichment.…”

We established an enrichment culture of marine anaerobic ammonium oxidation (anammox) bacteria using an upflow column reactor fed with artificial sea water supplemented with nitrogen and minerals and inoculated with coastal surface sediment collected from Hiroshima Bay. After 2 months of reactor operation, simultaneous removal of NH4 + and NO2− was observed, suggesting that an anammox reaction was proceeding. A total nitrogen removal rate of 2.17 g-N L −1 day −1 was attained on day 594 while the nitrogen loading rate was 3.33 g-N L −1 day −1 . Phylogenetic analysis revealed that at least two dominant "Candidatus Scalindua" species were present in this reactor. Moreover, many uncultured bacteria and archaea, including candidate division or ammonia-oxidizing archaea, were present. Fluorescence in situ hybridization (FISH) revealed that anammox bacteria accounted for 85.5 ± 4.5% of the total bacteria at day 393. We also designed two oligonucleotide probes specific to each dominant "Candidatus Scalindua" species. A simultaneous FISH analysis using both probes showed that two different "Candidatus Scalindua" species were clearly recognizable and coexisted during reactor operation, although there was some variation in their abundance. The marine anammox bacteria enriched in this study have potential applications to the treatment of industrial wastewater containing high levels of ammonium and salt.

The importance of anaerobic ammonium oxidation (anammox) -a metabolic pathway that can generate dinitrogen -remains poorly described in temperate estuarine systems. We evaluated the relative importance of anammox and denitrification along the salinity gradient of the Cávado River estuary (NW Portugal) during a seasonal survey. Potential rates of anammox and denitrification were measured in anaerobic sediment slurries using N 2 in the slurries was quantified using membrane inlet mass spectrometry (MIMS). Environmental parameters such as salinity, temperature and inorganic nitrogen were also monitored. Anammox and denitrification potentials in Cávado estuarine sediments varied from 0 to 3.3 and from 1.1 to 10.8 nmol N cm −3 wet sediment h −1 , respectively. During 1 sampling occasion, anammox activity accounted for as much as 72% of the measured production of dinitrogen, while annual averages varied from 17 to 33% depending on location. Nitrate availability and temperature appeared to be the primary environmental controls of anammox. Higher concentrations of NO 3 − and intermediate temperatures in the estuarine water (14 to 16°C) supported higher anammox activities. Using 16S rRNA gene-specific primers, anammox-like bacterial sequences were recovered from Cávado sediments -corroborating the measured anammox activities. Our results support the environmental importance of anammox for removal of nitrogen in estuarine sediments, and suggest that this process is apparently regulated by few variables.

“…Furthermore, all species share similar physiological traits (Kartal et al 2007;van de Vossenberg et al 2008). Anammox bacteria contain a separated intracytoplasmic compartment named the anammoxosome, where anammox catabolism was shown to take place Niftrik et al 2004Niftrik et al , 2008a.…”

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.
