“…Compared with the bacterial communities in the water column, variation was lower in the structures of bacteria communities in the sediment samples, which might be attributed to the thick sampling layer (10 cm) of sediment was used in our study. Sampling depth of sediment for bacterial analysis varied among different studies (Matulewich & Finstein 1978;Tamaki et al 2005), and bacteria in the sediment distributed in the surface layer (0-5 cm in depth) or oxic layer are more abundant and diverse (Li, Chen, Qu, Xin, Li & Zhao 2002;Song, Deng, Acosta-Martínez & Katsalirou 2008). Bacteria distributing in surface layer of sediment might be diluted when the thick sampling layer of sediment was used.…”

Bacterial communities in the water column and sediment of 12 commercial grass carp (Ctenopharyngodon idellus) farming ponds were analysed. At the same time, physical and chemical environmental parameters were measured, including secchi depth (SD), total nitrogen (TN), total phosphorus (TP) and chemical oxygen demand (CODMn). From 12 water samples and 12 sediment samples, 39 different ribotypes were detected with PCR‐denaturing gradient gel electrophoresis (PCR‐DGGE). The ribotype richness showed that bacterial species in the water column differed among these ponds, and the result of sequencing further revealed the dominant and common bacterial species. In total, 32 bacterial species belonging to seven phyla (Proteobacteria, Bacteroidetes, Actinobacteria, Cyanobacteria, Acidobacteria, Fibrobacteres and Fusobacteria) were identified. Ordination via canonical correspondence analysis (CCA) on the DGGE data and environmental parameters indicated that the composition of bacterial community was significantly influenced by SD.

“…10, but of net production rate for NH,+. Finstein (1978) suggest that the site of active nitrification in rivers may be at the bottom, rather than in the water column. In the Delaware, however, water-column processes account for most of the oxidation of NH,+ to NOz-and N03- (Fig.…”

A comprehensive investigation of the nitrogen cycle in the Delaware River was carried out using 15N tracers to measure rates for important transformations of nitrogen. Daily, depth-averaged 15N rates for the principal inorganic nitrogen species were consistent with rates derived from longitudinal profiles of concentration in the river.The data indicated that nitrification was a rapid, irreversible sink for NH4+, with export of the product N03-from the study area. Utilization of NO,-by primary producers was negligible, owing to low irradiance levels and to high NH,+ concentrations.The oxygen sag near Philadelphia was found to result from oxygen demand in the water column, with only minor benthic influence. Reaeration provided the major oxygen input. Nitrification accounted for about 1% of the net oxygen demand near Philadelphia but as much as 25% farther downstream.Many rivers and coastal waters act as treatment facilities for large inputs of primary-treated sewage. Microbial processes convert the organic material and inorganic nitrogen to more oxidized forms. Water quality declines owing to low oxygen concentrations, phytoplankton blooms, and high turbidity due to sewage-derived suspended particulate material. Investigation of the nitrogen cycle in such systems must account for the complexity and dynamic nature of the various nitrogen transformations and for the influence of light (Lipschultz et al. 198 5; Stanley and Hobbie 198 1;Dugdale and Goering 1967; Garside 198 l), dissolved oxygen content (Goreau et al. 1980; Lipschultz et al. 198 1;Lipschultz 1984), and flushing rates (Wofsy et al. 198 1).Most investigations of nitrogen cycling have been focused on a restricted subset of metabolic processes, principally phytoplankton uptake of NH,+ and N03-. Recent studies, however, have emphasized the need to expand the number of processes under investigation in order to understand the nitrogen cycle in a system (e.g. see Glibert et al. 1982;Lipschultz et al. 1985; Olson 198 1;McCarthy et al. 1984).We describe here 15N tracer experiments on the Delaware River intended to permit ' This work was funded by NSF grant BSR 83-16359 and by EPA grant R8 10219-01-O to Harvard University. identification of the important processes from an expanded set of nitrogen transformations and to relate the measured rates to observed changes in inorganic nitrogen concentration. Rates were integrated over depth and time to account for their sensitivity to light (Lipschultz et al. 198 5). This permitted quantitative comparisons and identification of the principal processes in the ecosystem. Net production (or loss) rates were then calculated for each inorganic nitrogen species at seven stations along the river near Philadelphia, and net production rates derived from 15N incubations were compared to net rates derived from river concentration data using a mass conservation model.

“…In our microbial-plant integrated systems, inoculation of INCB into the eutrophic water column could increase by 1 to 2 orders of magnitude compared to non-inoculated control, and the combination with macrophyte resulted in greater increase in these bacteria. These bacteria can distribute in different habitats: sediments, macrophyte and waterbody (Körner, 1999;Matulewich and Finstein, 1978). So the abundance of INCB in different habitats need further study.…”

“…Aquatic ecosystems play a major role in returning N 2 gas back to the atmosphere by bacteria-mediated processes of nitrification and denitrification (Matulewich and Finstein, 1978;Northup et al, 1995). Most aquatic ecosystems, including natural wetlands, have relatively poor inefficiency rates of producing N 2 gas, because of the low growth rates of nitrifying and denitrifying bacteria.…”

Eichhornia crassipes and Elodea nuttallii had different potentials in purification of eutrophic water. Floating macrophyte+bacteria (INCB) performed best in improving water quality (during the first experiment) and decreased total nitrogen (TN) by 70.2%, nitrite and ammonium by 92.2% and 50.9%, respectively, during the experimental period, when water transparency increased from 0.5 m to 1.8 m. When INCB was inoculated into the floating macrophyte system, the populations of nitrosating, nitrifying, and denitrifying bacteria increased by 1 to 2 orders of magnitude compared to the un-inoculated treatments, but ammonifying bacteria showed no obvious difference between different treatments. Lower values of chlorophyll a, COD(Mn), and pH were found in the microbial-plant integrated system, as compared to the control. Highest reduction in N was noted during the treatment with submerged macrophyte+INCB, being 26.1% for TN, 85.2% for nitrite, and 85.2% for ammonium at the end of 2nd experiment. And in the treatment, the populations of ammonifying, nitrosating, nitrifying, and denitrifying bacteria increased by 1 to 3 orders of magnitude, as compared to the un-inoculated treatments. Similar to the first experiment, higher water transparency and lower values of chlorophyll a, COD(Mn) and pH were observed in the plant+ INCB integrated system, as compared to other treatments. These results indicated that plant-microbe interaction showed beneficial effects on N removal from the eutrophic waterbody.
