Présentation

Je suis Directrice de recherches (DR2) au CNRS à l’Institut Méditerranéen d’Océanologie (MIO, unité mixte CNRS/AMU/IRD/UTLN) à Marseille.

J’effectue mes recherches en océanographie microbienne, en particulier l’étude de l’activité et de la régulation de la fraction hétérotrophe du compartiment bactérien en relation avec sa diversité et son rôle dans le réseau trophique microplanctonique et les cycles biogéochimiques.

Activité, cela signifie tout d’abord de pouvoir mesurer les flux d’utilisation et de transformation de la matière organique à toutes ses étapes : l’hydrolyse des polymères par les ectoenzymes, l’assimilation des monomères, la production bactérienne, la respiration.

Régulation, cela signifie déterminer les balances entre production et broutage (bottom up versus top down control); ca veut dire aussi déterminer la balance entre production et respiration des bactéries, i.e. mesurer son rendement de croissance ou BGE (bacterial growth efficiency). C’est mettre en relation les activités avec la biodisponibilité de la matière organique dont elles disposent : sa composition biochimique, son spectre de taille, les rapports stœchiométriques du carbone avec les autres éléments (N, P) qui la constitue.

En relation avec sa diversité, c’est savoir qui fait quoi. Ne plus appréhender la boite des « bactéries hétérotrophes » dans son ensemble mais connaître les organismes responsables des activités et savoir comment ils se succèdent en fonction de la qualité de la matière organique dont ils disposent, de la nature des processus qui contrôlent, des capacités métaboliques et cataboliques qu’ils possèdent.

Son rôle dans le réseau trophique microplanctonique et les cycles biogéochimiques, c’est établir les bilans de matière du réseau trophique microbien, par exemple établir les bilans de pyramide trophique ou étudier le couplage production primaire - production bactérienne. Les stocks et les flux sont toujours étudiés en fonction des conditions environnementales physiques, hydrodynamiques et à diverses échelles de temps et d’espace.

I am working as a CNRS senior research scientist, at the Mediterranean Institute of Oceanography in Marseille. This Institute is a mixed research unit, component of the Centre National de la Recherche Scientifique (CNRS), Aix-Marseille University (AMU), Toulon University (UTLN) and Institut de Recherches pour le Développement (IRD).

Research interest: Microbial Oceanography - Biogeochemical role of the heterotrophic prokaryotes in the marine environment.

I focus on the activity of heterotrophic prokaryotes within euphotic layers (production, respiration, bacterial growth efficiency, hydrolysis of macromolecules), in relation with the activity of phytoplankton and the stoichiometry of available nutrients (C/N/P) in their mineral and organic (particulate/dissolved) forms. I link these activities in relation with the taxonomic distribution of phytoplankton and heterotrophic prokaryotes, as well as the potential mixotrophy of some functional groups of phytoplankton.

I work principally within oligotrophic – open oceanic waters. Based in Marseille, my main natural laboratory is the P-limited Mediterranean Sea where I study competition between phytoplankton and heterotrophic bacteria for the availability of phosphorus. I study also a N-limited environment, the Western Tropical South Pacific, where di-nitrogen fixers are the main source of new N in the euphotic layers.

My tools: Flow cytometry and epifluorescence microcopy (abundances, cell sorting), radio-isotopic labeling (leucine and leucine techniques for heterotrophic bacterial production, spectrofluorimetry (fluorogenic substrates for ectoenzymatic activities), dilution/biodegradation experiments (bacterial growth efficiency), enrichment experiments (limitation factors), C and O budgets (balance autotrophy heterotrophy).
