Invisible but key players of biogeochemical cycles that underpin the functioning of the biosphere, the microorganisms have a considerable impact on the environment, health and economy. The microorganisms are, in fact, most of the diversity of the living world, and only the knowledge of the relationship between environmental changes and changes in the diversity of microbial communities can help control microbial processes that govern the operation and sustain our environment. The microorganisms are, in addition, of primary interest study models in molecular and cellular biology, genetics, immunology, in the field of evolution and ecology.
In the laboratory (UMR CNRS 6023), over 90 people are currently working on prokaryotic and eukaryotic microorganisms (Archaea, Bacteria, protists, fungi), as well as viruses, to different levels of integration, from molecular aspects to the cellular roles of these organisms in ecosystems.
The specificity of the laboratory is therefore to combine, in a single structure, skills and approaches in genomics, on one hand, and the level of population biology and ecosystems and ecology, on the other hand. A particular focus was on the development of molecular ecology, with the implementation of the latest tools of genomics and post-genomics science service issues related to the functioning of ecosystems, and interdisciplinary approaches.
The application areas of this work relate to the environment, especially to water resources management and soil remediation, and human and animal health since many parasites are related to microorganisms in particular Protistes.
