AbstractThe nitrogen mineralization capacity of soils characterizes the rate of organic nitrogen-containing compounds decomposition and reflects their ability to accumulate mobile mineral nitrogen, an objective indicator of the availability of this major nutrient to plants. We have studied gray forest soil (Luvic Greyzemic Phaeozem), widespread amo...

Ammonia oxidation is a significant process of nitrogen cycles in a lot of ecosystems sediments while there are few studies in shrimp culture pond (SCP) sediments. This paper attempted to explore the community diversity and abundance of ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB) in SCP sediments at different culture stages....

Agronomic, nutritional, and environmental aspects are integrated to promote sustainable tropical grassland production. Biological nitrification inhibition (BNI) is a plant-based strategy to improve nitrogen use efficiency by grasses in which they suppress the pace of soil nitrification via exudation of inhibitory compounds. To evaluate the effect o...

The third domain Archaea was known to thrive in extreme or anoxic environments based on cultivation studies. Recent metagenomics-based approaches revealed a widespread abundance of archaea, including ammonia-oxidizing archaea (AOA) of Thaumarchaeota in non-extreme and oxic environments. AOA alter nitrogen species availability by mediating the first...

Soil microbial transformations of nitrogen (N) can be affected by soil health management practices. Here, we report in situ seasonal dynamics of the population size (gene copy abundances) and functional activity (transcript copy abundances) of five bacterial genes involved in soil N cycling (ammonia-oxidizing bacteria [AOB] amoA, nifH, nirK, nirS, ...

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...

The cyclic nature of specific conversions in the nitrogen cycle imposes strict limitations to the conversions observed in nature and explains for example why anaerobic ammonium oxidation (anammox) bacteria can only use nitrite – and not nitrate – as electron acceptor in catabolism, and why nitrite is required as additional electron donor for inorga...

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...

Les filtres plantés de roseaux (FPR) constituent aujourd’hui un procédé de traitement des eaux usées avantageux du point de vue de leurs faibles coûts d’investissement/exploitation et de leur maintenance simple. Ce procédé largement développé en France depuis plus de 20 ans, notamment pour les petites collectivités, a montré de bonnes performances ...
