En résumé

Returning from a one year postdoctoral project at The National Autonomous University of Mexico (UNAM) on the study of Anammox process in extremophiles soil, I seek to integrate a dynamic team working on innovative projects.

I am now specialized in the study of complex microbial system in water and soil, extraction and characterisation of biomolecules, proteomics, enzymology, cell culture.

  • UNAM - Postdoctoral researcher

    Ciudad de México 2014 - 2015 Postdoctoral project: Demonstration of the presence of Anammox activity in hypersaline soils.

    The former Lake of Texcoco is an ancient salty lake located in the Valley of Mexico, more than 2,000 meters above mean sea level. This closed lake without current water outfall was drained to counter major problems of chronic flooding in the nearby city of Mexico.Its soils are saline and sodic, with a pH between 9.8 and 10.4, electrical conductivities in saturation extracts between 22 and 150 ms dm-1 and a large percentage of exchangeable sodium (60-80). In those extreme conditions, until now no anaerobic oxidation of ammonium (ANAMMOX activity) was ever observed. in order to determine the occurrence of this activity in those soils, ANAMMOX bacteria growth was specifically enhanced and the evolution of the concentrations of the different species of nitrogen were monitored.

    Toulouse 2008 - 2012 PhD project: Characterization Polymer matrix (EPS) of granular aerobic biomass

    For ten years, methods using aerobic granular sludge process for wastewater treatment have been extensively studied. Although the operating conditions leading to the production of dense microbial aggregates have been defined, little evidence has been reported about the biological mechanisms promoting the formation and stability of granules. However, exopolymeric substances (EPS) are major components of the extracellular matrix and various studies have suggested their involvement in the physicochemical properties of the formed granules (density, cohesion). To answer this question, a dual approach was undertaken, based partly on analysis of the chemical properties of the EPS extracted from granules, and also on measurement of the granule cohesion performed after enzymatic digestion or chemical treatment of the EPS matrix.

    At the end of this project we were able to determine the specific role of proteins and of the major specie of polysaccharides present in extracellular matrix. Thanks to this information, we built a structure model of granules explaining how the cohesion was maintained in the aggregate.
