Summary:A bacterial consortium well adapted to a complex medium can be easily maintained in a stable state and resist to environmental changes. To adapt to these changes, the consortium was able to exhibit elaborate behaviours and to maintain an invariant global "organization". The robustness and the coherence of such a consortium are linked to new and unexpected properties. These results are opposed to certain ideas concerning the prevalence of competition and the brittleness of cocultures. Such observations, although very fundamental, will open the way with the use of consortia to solve concrete problems in the fields of bioremediation and production.
