Abstract. Nitrification is a series of processes that oxidizes ammonia to nitrate, which contributes hypoxia development in coastal oceans, especially eutrophicated regions. The nitrification rate bulk water (NRb) and particle free (NRpf, > 3 μm eliminated) were determined along the Chang Jiang River plume August 2011 by nitrogen isotope tracer technique. Measurements dissolved oxygen (DO), community respiration (CR), nutrients, organic (DON), total suspended matter (TSM), particulate...
Prokaryotic microbes, the most abundant organisms in ocean, are remarkably diverse. Despite numerous studies of marine prokaryotes, zonation their communities pelagic zones has been poorly delineated. By exploiting persistent stratification South China Sea (SCS), we performed a 2-year, large spatial scale (10, 100, 1000, and 3000 m) survey, which included pilot study 2006 comprehensive sampling 2007, to investigate biological bacteria archaea using 16S rRNA tag shotgun metagenome sequencing....
Abstract. Dinitrogen (N2) and/or nitrous oxide (N2O) are produced through denitrification, anaerobic ammonium oxidation (anammox) or nitrification in sediments, of which entangled processes complicate the absolute rate estimations gaseous nitrogen production from individual pathways. The classical isotope pairing technique (IPT), most common 15N nitrate enrichment method to quantify has recently been modified by different researchers (1) discriminate between N2 denitrification and anammox...
Endozoicomonas are often predominant bacteria and prominently important in coral health. Their role dimethylsulfoniopropionate (DMSP) degradation has been a subject of discussion for over decade. A previous study found that degraded DMSP through the dddD pathway. This process releases dimethyl sulfide, which is vital corals coping with thermal stress. However, little known about related gene regulation metabolic abilities metabolism Endozoicomonadaceae. In this study, we isolated novel...
Abstract Endozoicomonas , the predominant bacterium associated with corals, is believed to play crucial roles in maintaining coral health. Its role dimethylsulfoniopropionate (DMSP) degradation has been a subject of discussion for over decade. A previous study found degraded DMSP through dddD pathway. This process releases dimethyl sulfide (DMS), which vital corals coping thermal stress. However, little known about related gene regulation and metabolic abilities metabolism...
Abstract. Nitrification rates of bulk water (NRb) and particle free (NRpf, > 3 μm eliminated) were determined along the Changjiang River plume in August 2011 by nitrogen isotope tracer technique. Dissolved oxygen (DO), community respiration rate (CR), nutrients, dissolved organic nitrogen, total suspended matter (TSM), particulate carbon/nitrogen (POC/PON), acid-leachable iron manganese on particles both archaeal β-proteobacterial amoA abundance size-fractioned (> 0.22–3 μm) measured....
Abstract Reservoirs are active sites in the terrestrial environment terms of carbon transformation and storage. Continuous reservoir construction reinforces importance such artificial storage; however, knowledge pertaining to sources, cycling, preservation autochthonous/allochthonous particulate organic (POC) reservoirs remains incomplete. We monitored flux isotope composition sinking particles a subtropical deep reservoir, results were compared with isotopic signatures potential POC sources...
Abstract. Dinitrogen (N2) and/or nitrous oxide (N2O) are produced through denitrification, anaerobic ammonium oxidation (anammox) or nitrification in sediments, of which entangled processes obfuscate the absolute rate estimation gaseous nitrogen production from individual pathway. Recently, classical isotope pairing technique (IPT), most common 15N-nitrate enrichment method to quantify has been modified by different researchers (1) discriminate relative contribution N2 denitrification...
<p>Although global models of nitrogen (N) cycling typically focus on nitrate ecosystem N saturation, dissolved organic (DON) is the dominant form export from many watersheds. In previous hypotheses, DON dynamics in watersheds was treated as being functionally equivalent to inorganic forms. However, unlike N, contained within molecules controlled not only by direct biological demand for but also heterotrophic reduced C, which attached. During 2016-2018, we evaluated release...
