Denitrification Performance and Microbial Community Structure of a Combined WLA–OBCO System
The contamination of surface water by nitrogen due to fertilizer application and discharge of wastewater is an increasingly serious problem. A multifunctional device, which combines water-lifting and aeration (WLA) with oligotrophic biological contact oxidation (OBCO), was developed for pretreatment of raw water to reduce nitrogen. The performance of nitrogen removal and changes in microbial co...
متن کاملDenitrification and the Denitrifier Community in Coastal 1 Microbial
18 Denitrification was measured in three structurally different coastal microbial mats by 19 using the stable isotope technique. The composition of the denitrifying community was 20 determined by analyzing the nitrite reductase (nirS and nirK) genes using clone libraries 21 and the GeoChip. The highest potential rate of denitrification (7.0±1.0 mmol N m d) 22 was observed during summer at stati...

متن کاملThe Oldest Operating Wetland Mitigation Bank In The U . S . A Review
The construction of a wetland as a means of compensating for the loss of a natural wetland has been an operative practice in the management of the resource for many years. Generally, compensation by creation of new areas is a last resort in the mitigation sequencing used by wetlands management programs. Typically, development of a land parcel must first attempt to avoid any wetlands present. Wh...
متن کاملMicrobial Community Structure in Lake and Wetland Sediments from a High Arctic Polar Desert Revealed by Targeted Transcriptomics
While microbial communities play a key role in the geochemical cycling of nutrients and contaminants in anaerobic freshwater sediments, their structure and activity in polar desert ecosystems are still poorly understood, both across heterogeneous freshwater environments such as lakes and wetlands, and across sediment depths. To address this question, we performed targeted environmental transcri...
