RechercheLe cycle biogéochimique des gaz à l’état de trace contribuant soit directement ou indirectement au bilan radiatif terrestre constitue le thème central des recherches de Philippe Constant. Ses travaux visent entre autres à identifier les micro-organismes modulant le bilan atmosphérique des gaz à l’état de trace et à prédire l’impact du changement global sur leurs fonctions biogéochimiques. Les micro-organismes ayant le pouvoir d’oxyder les gaz présents à l’état de trace dans l’atmosphère sont dotés de voies métaboliques ayant évolué en intégrant des enzymes démontrant une affinité extrêmement élevée pour leur substrat. Chez certaines bactéries, la capture des gaz à l’état de trace procurerait une source d’énergie alternative pour la survie ou la production de métabolites secondaires. L’évaluation du potentiel biotechnologique de ces micro-organismes représente également un objectif important à l’agenda de l’équipe de recherche de Philippe Constant, qui oriente ses travaux afin de répondre à ces questions d’intérêt général :
