Have we overemphasized the role of denitrification in aquatic ecosystems? A review of nitrate removal pathways
© The Ecological Society of America www.frontiersinecology.org E nitrogen (N) concentrations, often in the form of nitrate, present a water-quality problem of growing concern. Nitrate concentrations in groundwater and rivers in developed areas of the world have risen substantially as a result of the use of synthetic N fertilizers and cultivation of N-fixing crops (Turner and Rabalais 2003). Inc...
متن کاملNitrate Removal from Wastewater through Biological Denitrification with OGA 24 in a Batch Reactor
Nitrates pollution of waters is a worldwide problem and its remediation is a big challenge from the technical and the scientific point of view. One of the most used and promising cleaning techniques is the biological treatment of wastewaters operated by denitrifying bacteria. In this paper we begin a thorough study of denitrifying performances of the bacterium Azospira sp. OGA 24, recently isol...
متن کاملRemoval of highly elevated nitrate from drinking water by pH-heterogenized heterotrophic denitrification facilitated with ferrous sulfide-based autotrophic denitrification.
The performance of acetic acid-supported pH-heterogenized heterotrophic denitrification (HD) facilitated with ferrous sulfide-based autotrophic denitrification (AD) was investigated in upflow activated carbon-packed column reactors for reliable removal of highly elevated nitrate (42 mg NO(3)-Nl(-1)) in drinking water. The use of acetic acid as substrate provided sufficient internal carbon dioxi...
متن کاملDenitrification and environmental factors influencing nitrate removal in Guaymas Basin hydrothermally altered sediments
We measured potential nitrate removal and denitrification rates in hydrothermally altered sediments inhabited by Beggiatoa mats and adjacent brown oil stained sediments from the Guaymas Basin, Gulf of California. Sediments with Beggiatoa maintained slightly higher rates of potential denitrification than did brown sediments at 31.2 ± 12.1 versus 21.9 ± 1.4 µM N day(-1), respectively. In contrast...
متن کاملLong-term tillage and residue management effect on soil compaction and nitrate leaching in a Typic Haploxerert soil
A field experiment was conducted to compare the effects of long-term tillage and cropresidue management on some physical properties and nitrate leaching of a Typic Haploxerertsoil under winter wheat (Triticum vulgare L.)-soybean (Glycine max L.) double-croppingsystem. The tillage systems consisted of conventional tillage with stubble (CT1), conventionaltillage with stubbles burned (CT2), heavy ...
