Méta-omiques et écosystèmes microbiens

Le métaprogramme MEM initié en 2010, est un programme de recherche transdisciplinaire et transversal qui implique des équipes de microbiologistes associés à des mathématiciens concernés par des approches globales de différents écosystèmes microbiens.

Le préfixe Méta- signifie «ce qui est au-delà de, ce qui dépasse et englobe». Le suffixe -omique correspond à des technologies qui permettent d'étudier un grand nombre de données concernant un ensemble d'objets biologiques, telles qu'un ensemble de gènes (génomique), d'ARN (transcriptomique), de protéines (protéomique), de métabolites (métabolomique), etc...

Les approches méta-omiques sont donc utilisées pour appréhender dans leur globalité des écosystèmes microbiens complexes tels que l'ensemble des micoorganismes du sol, de l'intestin humain ou des aliments fermentés.
