The process of nitrite-dependent anaerobic methane oxidation (n-damo) was recently discovered and shown to be mediated by "Candidatus Methylomirabilis oxyfera" (M. oxyfera). Here, evidence for n-damo in three different freshwater wetlands located southeastern China obtained using stable isotope measurements, quantitative PCR assays, 16S rRNA particulate monooxygenase gene clone library analyses. Stable experiments confirmed the occurrence examined wetlands, potential rates ranged from 0.31...
The Qiantang River is a typical freshwater ecosystem that acts as an irreplaceable water source in Zhejiang Province southeastern China. However, the effects of environmental factors on bacterial community this have not been determined. In study, seven sediment samples were collected along river. Their communities identified using 454 high-throughput sequencing, and primary responsible for shaping structure analyzed. number operational taxonomic units (OTUs) ranged from 2637 to 3933. Using...
Anaerobic ammonium oxidation (anammox) and nitrite-dependent anaerobic methane (n-damo) are two of the most recent discoveries in microbial nitrogen cycle. In present study, we provide direct evidence for cooccurrence anammox n-damo processes a flooded paddy field southeastern China. Stable isotope experiments showed that potential rates ranged from 5.6 to 22.7 nmol N2 g(-1) (dry weight) day(-1) varied 0.2 2.1 CO2 different layers soil cores.

Abstract Anaerobic oxidation of methane (AOM) reduces emissions from marine ecosystems but we know little about AOM in rivers, whose role the global carbon cycle is increasingly recognized. We measured potentials driven by different electron acceptors, including nitrite, nitrate, sulfate, and ferric iron, identified microorganisms involved across contrasting riverbeds. activity was confined to more reduced, sandy riverbeds, whereas no less gravel riverbeds where there were few anaerobic...
ABSTRACT Anaerobic ammonium-oxidizing (anammox) bacteria have been detected in many marine and freshwater ecosystems. However, little is known about the distribution, diversity, abundance of anammox terrestrial In this study, were found to be present various agricultural soils collected from 32 different locations China. Phylogenetic analysis 16S rRNA genes showed “ Candidatus Brocadia,” Kuenenia,” Anammoxoglobus,” Jettenia” soils, with Brocadia” being dominant genus. Quantitative PCR that...
Anaerobic ammonium oxidation (anammox) is an important process in the marine nitrogen cycle. However, little known about distribution, diversity and abundance of anammox bacteria inland river ecosystems. Here, we found presence diverse a freshwater - Qiantang River, Zhejiang Province (China). The phylogenetic analysis 16S rRNA genes showed that Brocadia genus, Kuenenia Scalindua genus three new bacterial clusters could be detected together River sediments, suggesting higher ecosystem than...
Ammonia oxidation is performed by both ammonia-oxidizing archaea (AOA) and bacteria (AOB). However, the current knowledge of distribution, diversity, relative abundance these two microbial groups in freshwater sediments insufficient. We examined spatial distribution analyzed possible factors leading to niche segregation AOA AOB Qiantang River, using clone library construction quantitative PCR for archaeal bacterial amoA genes. pH NH4(+)-N content had a significant effect on operational...
Nitrite-dependent anaerobic methane oxidation (n-damo), which couples the of to denitrification, is a recently discovered process observed in "Candidatus Methylomirabilis oxyfera". M. oxyfera affiliated with "NC10" phylum, phylum having no members pure culture. Based on isotopic labeling experiments, it hypothesized that has an unusual intra-aerobic pathway for production oxygen via dismutation nitric oxide into dinitrogen gas and oxygen. In addition, bacterial species unique ultrastructure...
