  • research domains

    LCSNSA’s main topic explores tropical biodiversity in the south-western
    Indian Ocean and agri-industrial systems by studying their properties as part
    of sustainable, innovative chemistry, linked to the tropical bioeconomy. Its
    main objectives are :

    • Identifying and promoting natural resources derived from marine and
      terrestrial biodiversity (plants, marine invertebrates and micro organisms).
    • The search for useful molecules to use and produce in the fields :

    (1) of pharmacology and cosmetics,

    (2) colourings, pigments and flavouring,

    (3)the environment and bioenergy, and

    (4) chemical ecology.

     

    Areas of expertise

    • Secondary metabolite analysis from plants, marine organisms and micro-organisms, including :
      – Extraction, bio-guided sub-division and isolation of molecules using chromatographic techniques (TLC, CLMP, HPLC) ;
      – Identification and structural characterisation of molecules using spectroscopy techniques (NMR mono- and bi-dimensional, SMHR, GC-MS, HPLC-MS, UV, IR) and quantum chemical methods (molecular modelling).
    • Exploration of production of colourings, flavouring and bioactive products using microbial methods. Development of micro-organisms.

  • Main scientific collaborations

    GDR 3658 MEDIATEC : CHEMICAL MEDIATION IN THE
    ENVIRONMENT – CHEMICAL ECOLOGY / NATIONAL
    This research group (GDR) seeks to promote chemical ecology in
    France, to foster a scientific community of biologists, ecologists
    and chemists with an interest in marine and continental
    environments, microorganisms, plants, invertebrates, insects and
    mammals. It also addresses current scientific challenges through
    global and transversal “omic”-type approaches, from genomics to
    environmental metabolomics.

    QUALIREG / REGIONAL AND INTERNATIONAL
    Regional food industry cooperation network (50 partners) to
    improve product quality and promote co-development in the
    Indian Ocean area. Participation in continuing professional
    education.
