Laboratory of Microalgal and Bacterial Bioenergetics and Biotechnology (LB3M)
Research and biotechnological applications in the field of photosynthesis, hydrogen and biodiesel production by photosynthetic micro-organisms (microalgae, cyanobacteria).
The main scientific objectives of the laboratory are to understand the photosynthetic mechanisms of conversion and storage of the light energy by microalgae or cyanobacteria, to identify the limiting steps and to define and validate strategies of optimization in order to propose new ways of production of biofuel (biohydrogene, biodiesel).

Laboratory of Microbial Ecology of the Rhizosphere and Extreme Environments (LEMIRE)
The research goals of the LEMIRE are :
- to understand how the rhizosphere functions by characterizing the carbon fluxes and molecules exuded by plants and the structuring effect they have on soil bacteria populations. The Pseudomonas brassicacearum-Arabidopsis thaliana model is used to decode the molecular dialog between plants and bacteria and to determine the effects of their association on plant physiology and health and vice versa.
- to characterize tolerance mechanisms to ionising radiation and desiccation in Deinococcus deserti.
- to study the Ramlibacter tataouinensis cell cycle and its tolerance to desiccation.

Membrane exchange and signaling laboratory (LEMS)
We are studying signal transduction mechanisms and transporters involved in osmoregulation and cell detoxification in response to biotic and abiotic stress in higher plants.
Research group in applied phytotechnics (GRAP)
The mission of the GRAP is that of a service provider for its "client" laboratories. Within this framework, specific experimental conditions are possible upon demand.
Laboratory of developmental plant biology (LBDP)
The main goal of the LBDP is to elucidate the phosphate signalling pathway in plants. Besides its interest for fundamental research (mechanisms triggering ion perception by plants remain mostly unknown), Pi modulates the availability of cations (including metals) in soil and is also a key parameter controlling the production of energetic compounds (starch, lipids). Therefore, our research may find applications in the field of bioenergy and bioremediation.
Cellular Bioenergetics Laboratory (LBC)
The LBC laboratory is studying the nature, structure and function of different soluble and membrane-bound proteins involved in bacterial mechanisms of bioenergetic oxidoreduction and metallic or xenobiotic stress resistance.
Laboratory for protein metal interaction studies (LIPM)
Constituted in 2006, the Laboratory of Protein Metal Interactions (Laboratoire des Interactions Protéine Métal, LIPM) develops researches in the field of environmental nuclear toxicology.
The objectives of the Laboratory are the analysis of mechanisms involved in the physiological response related to bacteria exposure to toxic metals, radionuclides and in particular uranium, on environmental bacteria from naturally uranium-rich or radionuclide contaminated soils, and on Escherichia coli; the analysis of target proteins of metals and of structural determinants of metal sites properties, with the longer-term objective to engineer uranium binding architectures.
These projects are carried out by a multidisciplinary approach of microbiology, genetics, biochemistry combined with the use of mass spectrometry and infra-red spectroscopy (IRTF) for the study of the metal sites in proteins.

Laboratory of plant molecular ecophysiology (LEMP)
The Laboratory is interested in the response of photosynthetic processes to environmental factors.
Our objectives are to describe the mechanisms that regulate energy fluxes, gas exchanges and redox equilibrium in the chloroplast and the leaf, and to study protection, repair and signaling mechanisms in the chloroplast, in particular the reactions associated with photooxidative stress
