The anaerobic ammonium-oxidizing (anammox) and nitrite-dependent methane-oxidizing (n-damo) bacteria in a paddy soil core (0-100 cm) were investigated with newly designed primers targeting the hydrazine synthase β-subunit (hzsB) of anammox recently published pmoA 16S rRNA genes n-damo bacteria. hzsB gene was identified as proper biomarker to explore bacterial biodiversity abundance soil. present throughout highest 2.7 × 10(6) copies g(-1) dry at 40-50 cm not detectable below 70 cm.

Abstract Achieving nitrogen removal from domestic wastewater using anaerobic ammonium oxidation (anammox) has the potential to make treatment energy-neutral or even energy-positive. The challenge is suppress growth of nitrite-oxidizing bacteria (NOB). This study presents a promising method based on intermittent aeration with low dissolved oxygen limit NOB growth, thereby providing an advantage anammox form partnership ammonium-oxidizing (AOB). results showed that was successfully suppressed...
The electrolysis of nitrate reduction to ammonia (NRA) is promising for obtaining value-added chemicals and mitigating environmental concerns. Recently, catalysts with high-performance synthesis from has been achieved under alkaline or acidic conditions. However, NRA in neutral solution still suffers the low yield rate selectivity due binding affinity nucleophilicity NO 3 − . Here, we confirmed that in-situ-generated Fe(II) ions existed as specifically adsorbed cations inner Helmholtz plane...
The hypothesis of an anammox hotspot in river riparian zones was put forward based on our investigation freshwater ecotones for over 25 years and previous research. Here we used a complementary array methods including isotope-pairing technique, quantitative PCR assays, 16S rRNA hydrazine synthase gene (hzsB) clone libraries to document the spatiotemporal evidence high abundance zone bacteria sediment with observed 1.3-12 × 10(6) (summer) 1.4-20 10(8) (winter) copies g(-1), which is highest...
An integrated approach to document high anammox activity and biodiversity in a constructed wetland (CW) was performed showed that substantial could mitigate undesirable N(2)O emission. The enhanced bacterial abundance, were achieved by supplementing activated sludge the CW. Up 3.38 × 10(7) gene copies g(-1) dry soil of bacteria enriched measured isotope pairing technique increased from 1.6 nmol N h(-1) original 18 CW, with specific cellular 5.1 12.8 fmol cell(-1) d(-1). 33% produced N(2) be...
The anaerobic oxidation of ammonium (anammox) process has been observed in diverse terrestrial ecosystems, while the contribution anammox to N2 production paddy soils is not well documented. In this study, activity and abundance diversity bacteria were investigated assess potential 12 typical collected southern China. Anammox related "Candidatus Brocadia" Kuenenia" two novel unidentified clusters detected, with comprising 50% population. prevalence was confirmed by quantitative PCR results...
Abstract Anaerobic oxidation of ammonium (anammox) is recognized as an important process for nitrogen (N) cycling, yet its role in agricultural ecosystems, which are intensively fertilized, remains unclear. In this study, we investigated the presence, activity, functional gene abundance and anammox bacteria rhizosphere non-rhizosphere paddy soils using catalyzed reporter deposition–fluorescence situ hybridization, isotope-tracing technique, quantitative PCR assay 16S rRNA clone libraries....
Summary The distribution and importance of anaerobic ammonium oxidation (anammox) nitrite‐dependent methane (n‐damo) have been identified in aquatic ecosystems; their role agricultural upland soils however has not yet well investigated. In this study, we examined spatio‐temporal distributions anammox n‐damo bacteria soil profiles (300 cm depth) from an upland. Monitoring nitrogen (N) conversion activity using isotope‐tracing techniques over the course one year showed denitrification (99.0%...
