Research in LEMiRE addresses questions about the adaptive responses of bacteria to environmental fluctuations. Based on an integrative approach and functional genomics tools, these studies build our knowledge of the functioning of environmental bacteria and of how bacteria acclimate to environmental stress.
Ramlibacter tataouinensis TTB310, a betaproteobacterium isolated from a semi-arid region of South Tunisia (Tataouine), is characterized by the presence of both cyst-like and rod-shaped cells in pure culture. The original cell cycle of strain TTB310, with desiccation tolerant cyst-like cells capable of division and desiccation-sensitive motile rods capable of dissemination, appears to be a novel adaptation for life in a hot and dry desert environment.
We use R. tataouinensis as bacterial model to address questions on bacterial adaptation to dry and hot desert, especially through the effect of light on cell cycle.
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
