Étude de la survie de contaminants bactériens modèles d’origine industrielle, isolés d’environnements oligotrophes, et élaboration de milieux synthétiques permettant leur croissance

Abstract : The development of culture media to quickly and reproducibly detect fastidious microorganisms represents a significant change in the control of industrial products and processes.Two synthetic culture media have been developed to reach specifications. The development was performed by combining the analysis of nutritional compounds to the study of specific bacterial metabolisms. The formulations of the resulting culture media allow the growth of microorganisms with different nutritional requirements as those frequently isolated in industrial water.In parallel experiments on multi-species biofilms, using bacteria isolated from industrial water systems, it was observed that the survival of bacteria in nutrient-poor environments is dependent on cooperative interactions, based on "swarming" and "hitchhiking".
