A full-scale biofilm-enhanced aerated lagoon using fixed submerged media was monitored using automated water quality monitoring stations over the span of one year to quantify its nitrification performance. The system was operating at a high organic loading rate averaging 5.8 g total CBOD5 /m2 of media per day (23.9 g total CBOD5 /m3 of lagoon per d...

En assainissement, la nitrification est une étape de traitement biologique qui permet, par l’intermédiaire de bactéries nitrifiantes, de transformer les ions ammonium en ions nitrate. Les ouvrages dans lesquels se déroule la nitrification sont construits avec des matériaux cimentaires qui subissent des dégradations de plus en plus visibles ces dern...

Invasive plants often change a/biotic soil conditions to increase their competitiveness. We compared the microbially-mediated soil nitrogen (N) cycle of invasive Mikania micrantha and two co-occurring native competitors, Persicaria chinensis and Paederia scandens. We assessed how differences in plant tissue N content, soil nutrients, N cycling rate...

One of the major global challenges of this century is to find the balance between the intensive agricultural production and the environmental damage that it causes by contributing to climate change and deterioration of water resources and soils. Agriculture accounts for up to one third of anthropogenic emissions of greenhouse gases (GHGs) which exa...

AbstractSoils are among the main biological sources of nitrous oxide (N2O), and nitrification and denitrification processes are the major N2O production factors in soils. The nitrogen of mineral and organic fertilizers applied to the fields is easily involved in the biogeochemical cycle of soil nitrogen and contributes to the N2O emission to the at...

Adding nitrogen fertilizers to agricultural soils contributes to increasing concentrations of nitrous oxide (N2 O) in the atmosphere. However, the impacts of N addition on soil organic matter (SOM) turnover, SOM availability, and the ensuing SOM-derived N2 O emissions remain elusive. Within this context, the net change in direction and rate of SOM-...

Many drinking water utilities in the United States using chloramine as disinfectant treatment in their drinking water distribution systems (DWDS) have experienced nitrification episodes, which detrimentally impact the water quality. Identification of potential predictors of nitrification in DWDS may be used to optimize current nitrification monitor...

Ammonia-oxidizing archaea (AOA) are ubiquitous in diverse ecosystems and play a pivotal role in global nitrogen and carbon cycling. Although AOA diversity and distribution are widely studied, mainly based on the amoA (alpha subunit of ammonia monooxygenase) genotypes, only limited investigations have addressed the relationship between AOA genetic a...

AbstractThe plant biomass (postharvest and crop residues, green manure crops, etc.) actively used in Siberian agriculture partly contributes to the replenishment of mineral nutrients needed to sustain field crop yields and to maintain soil fertility. A comparative assessment of kinetic parameters for mineralization of manure, green manure crops (sw...
