Les bioréacteurs de grandes dimensions, en raison de phénomènes de transfert limitant, sont le siège d’hétérogénéités se traduisant par des gradients locaux de concentration et température. Les microorganismes circulant au sein de ces bioréacteurs subissent donc des fluctuations environnementales qui peuvent affecter leur comportement aux niveaux métaboliques et/ou moléculaires. La réponse microbienne est fonction de la nature, de l’intensité, de la fréquence et de la durée de la perturbation. L’objectif de ce travail est l’étude quantitative de l’impact de l’intensité, la fréquence et l’amplitude d’un stress nutritionnel sur le comportement dynamique d’Escherichia coli, à savoir des ajouts pulsés de glucose lors de cultures continues en ré...
