Molecular ecology of denitrifiers

Résumé

Denitrifying micro-organisms are capable to reduce soluble oxidized nitrogen compounds into gaseous N2 O or N2 for energy conservation. the denitrification process has received a lot of attention because it accounts for significant losses of nitrogen fertilizer from agricultural soils. Denitrification is also responsible for the emission of N2 O, an important greenhouse gas with a global warming potential 250 times higher that of carbon dioxide. understanding the relationships between denitrifier community ecology and N-fluxes by denitrification is therefore important for a better management of N-input in agriculture and mitigation strategies. indeed, the last decade several molecular methods have been developed and extensively applied to study the diversity, the abundance and the distribution of the denitrifying community in the environment. this talk will summarize our current knowledge of this functional community and of its environmental controls and present some preliminary steps toward bridging denitrifier community ecology and denitrification process.
