Micro-organisms are largely responsible for the flow of matter and energy in the biosphere and are important actors in the functioning and dynamics of ecosystems. We focus our research on 2 bacterial functional groups involved in the nitrogen cycle (nitrifiers, denitrifiers) and to a lesser extent on mineralizers and free nitrogen fixers. These functional groups are responsible for complementary processes that are key steps in the nitrogen cycle. The group of nitrifiers, responsible for the oxidation of ammoniacal and / or nitrous nitrogen) and the group of denitrifiers, responsible for the reduction of the oxidized forms of nitrogen, are functionally connected at the level of nitrite and / or nitrate. Nitrification, denitrification and fixation participate jointly and in connection with mineralization in the control of nitrogen exchanges between the biosphere and the atmosphere and in the equilibrium between the main forms of mineral nitrogen assimilable by plants (ammonium and nitrate). Nitrification and denitrification are involved in the loss of nitrogen from the soil system, in the control of the nitric load of surface or phreatic waters, as well as in the emission of trace pollutant gases (nitrogen oxides).

Our research themes are organized schematically in four main areas :

  • An important aspect of the work of our team is the study of the mechanisms of regulation of the intensity of the functions ensured by model microorganisms or functional groups of model microorganisms, taking into account the different levels of regulation possible, namely the the diversity, diversity and functionality of these organizations. An important issue here is to elucidate the modalities of the expression of genes encoding key enzymes (nitrate reductase, nitrite oxido-reductase ...) in the laboratory and in natural conditions. This makes it possible to specify the determinism of the niche of these organisms and their distribution in space.
  • A second key aspect of our work is to analyze the diversity-function relationships in these microbial groups, and more specifically to evaluate the role of taxonomic and functional diversity, in interactions with environmental conditions, on the achievement of the function provided. by these model microbial groups. The notion of functional complementarity between microorganisms with different niches is particularly used to better understand the diversity-functioning relationships.
  • A third important aspect of our team’s work is to evaluate the effect of plant diversity, and in particular plant functional diversity, on the diversity and functioning of nitrifying and denitrifying groups. This takes into account different types of possible mechanisms, ranging from direct impacts of plants on microbial communities (exudation of specific compounds having a trophic or even signaling role) to indirect impacts on environmental variables influencing microbial groups.
  • Finally, a fourth key aspect of our work is the study of the effects of different factors of global changes (climate change and / or changes in land use patterns) and the ecology of stress (extreme events, pollutants) on the environment. activity, size and diversity of model functional groups, focusing on their role in the functioning of ecosystems.

To achieve these objectives, our team has standard tools and innovative tools to characterize the workforce (quantitative PCR, flow cytometry), diversity (metagenomics and high-throughput sequencing targeting particular genes specific functional groups ... ), the key enzyme pools (serology) and the activity (measurement by gas chromatography, 15N isotope dilution crude nitrogen flux measurement) of the nitrifying, denitrifying and fixing groups as well as the bacterial community as a whole. It should be noted that our team has developed for the first time a tool to characterize the diversity of the Nitrobacter nitrating community in environmental samples by targeting the nxrA gene. In order to characterize the mechanisms regulating denitrification and nitrification, our team uses bacterial genetics methods (transcriptional and translational fusion, mutant construction, measurement of ß-galactosidase activity ...). Our team is also increasingly using analytical methods to characterize the diversity of natural substances in the rhizosphere and soil, as well as the bacterial metabolome. Finally, to address the high-throughput approaches of modern biology, we regularly use robotic methods available in the laboratory.

In addition, members of the team have a key role in major research and training projects of regional, national and international scope :

  • The Institute of Environmental Engineering and Ecodevelopment (IG2E) is directed by A. Richaume-Jolion (
  • The European network BiodivERsA, supported by the European Commission through its H2020 programme, is coordinated by X. Le Roux (
