METAFUN

Functional metagenomics

Investigation of unknown bacterial for the discovery of new bioactives compounds

This innovative approach is based on a set of high throughput screening technologies enabling the analysis of the entire genome of all microorganisms belonging to an ecological niche, including those which are not cultivable.

Hervé Blottière - Scientific director of Metafun

An automated process ensuring high throughput screening

  • 575,000

    manufactured clones

  • 23 MILLION

    cloned unknown genes

  • 400,000

    genes tested / week

  • A certified method for libraries production

    Construction of large insert genomic and metagenomic libraries

    Functional screening of large clone libraries with thousands genomic or metagenomic DNA fragments >> Identification of bacteria – cell cross-talk

    Implementation of cell-based bioassays using a high-throughput strategy >> Identification of functional bacterial genes and metabolic pathways involved in the dialogue with the host

  • Partnerships

    METAFUN is ready to collaborate with the scientific and industrial communities, by applying its skills and know-how for:

    The design of functional metagenomic projects:
    – Expert advice to design the study
    – Construction of large insert genomic and metagenomic libraries
    – Functional screening and analysis

    High throughput screening from existing libraries: from the construction of the project to the analysis of the results

     Main research areas with our industrial partners:
    – Screening for microbial species/strain that may interact with the host
    – Identification of the function of a species/strain on a specific metabolic pathway: immunity, intestinal barrier, inflammation, taste receptor, oxidative stress.
    – Impact of a molecule or nutrient on microbial metabolism (synthesis or catabolism: bacterial metabolites)
