Abstract Denitrification, anaerobic ammonium oxidation (anammox), and dissimilatory nitrate reduction to (DNRA) are three competing processes of microbial that determine the degree ecosystem nitrogen (N) loss versus recycling. However, global patterns drivers relative contributions these N cycling soil or sediment remain unknown, limiting our understanding balance management. Here, we compiled a dataset 1570 observations from wide range terrestrial aquatic ecosystems. We found...
Abstract The importance of denitrification and anaerobic ammonium oxidation (anammox) in removing nitrogen (N) from upland runoff has been well documented riparian wetlands. However, the relative contributions anammox to N removal rhizosphere non‐rhizosphere soils zones remain unclear. Here, we explored rates bulk (0–5 10–15 cm) 39 wetlands along Yangtze River using 15 isotope pairing technique. Additionally, used a quantitative polymerase chain reaction assay determine abundance soil...
The spatial pattern and driving mechanism of biodiversity along elevational gradients are key topics in ecology. However, it is still unclear whether the multidimensional diversity different types organisms shows a similar response to elevation changes. Here, we measured species phylogenetic plants, bacteria, fungi, microbial functional groups (nitrifiers, denitrifiers, methanogens, methanotrophs) 36 wetland sites on Qinghai-Tibetan Plateau. results showed that both fungi exhibited...
A central goal in microecology is to understand the ecological factors shaping spatial patterns of microbial communities and underlying mechanisms. However, biogeographical functional groups involved nitrogen cycling (e.g., nitrifiers denitrifiers) their drivers at a large scale remain poorly understood. In this study, we evaluated geographical distributions denitrifiers riparian rhizosphere soils, bulk channel sediments 30 river regions along latitudinal gradient from 21.8°N 45.1°N across...
Anaerobic ammonium oxidation mediated by MnO2 (termed Mn-ANAMMOX) is a newly discovered microbial nitrogen removal pathway. However, few studies have reported on the Mn-ANAMMOX process and related communities in agricultural drainage ditches. In this study, Mn(Ⅳ)-reducing bacteria (MnBR) enrichment cultivation was carried out for 340 days an isotope tracing technique high-throughput sequencing technology were used to provide convincing evidence of occurrence Mn-ANAMMOX. The results showed...
Anaerobic ammonium oxidation coupled to iron (Ⅲ) reduction (termed Feammox) is a recently discovered pathway of nitrogen cycling. However, little known about the pathways N transformation via Feammox process in riparian zones. In this study, evidence zone soil layers (0-20 cm) was demonstrated using isotope tracing technique and high-throughput sequencing technology. The results showed that occurred zones four different (A:0-5 cm, B:5-10 C:10-15 D:15-20 rates ranged from 0.25 mg·(kg·d)-1...
Feammox is a newly discovered process of anaerobic ammonium oxidation driven by Fe(III) reduction. Nitrate-dependent Fe(II) (NDFO) the coupling and nitrate reduction to produce N 2 under conditions. It has not been reported whether two reactions exists in natural enrichment. In this study, enrichment culture experiments were carrired out prove occurrence with NDFO. The results indicate that removal efficiencies nitrogen total incubation about 92.9% 20% respectively. Organic carbon sodium...
Surface water, Elodea nuttallii and undisturbed sediment cores from the Qinshui River in Gonghu Bay were collected to carry out a simulation experiment laboratory study effect of nuttallii-immobilized nitrogen-cycling bacteria on nitrogen removal mechanisms river water. In this study, transformation fate ammonium among four different treatment groups investigated by using stable 15 N isotope pairing technique combined with high-throughput sequencing technology[Treatment A:bare sediment,...
To explore the rate variation and contribution to N loss of denitrification anaerobic ammonia oxidation (ANAMMOX) in nitrogen migration process farmland soils southern China, we assess physicochemical characteristics soil samples different layers from land use types (farmland, river channel, riparian zone, lake sediment) a wheat-rice rotation area Wanshandang Lake. Illumina MiSeq sequencing quantitative real-time polymerase chain reaction (qPCR) are used investigate microbial community...
The process of complete ammonia oxidation (comammox), which can convert into nitrate in one step, has recently changed the concept traditional nitrification. However, comparative studies comammox different ecosystems and microbial community analysis are still scarce. In this paper, distribution diversity farmlands, riparian zones, river sediments summer winter were investigated by high-throughput sequencing fluorescence quantitative techniques. relationships between other microorganisms...
