Thesis subject: Inferring model metabolism of reduced microbial community

Presentation

I worked in the Dyliss Team as an engineer and a PhD student by developing methods to study the metabolism of organism. This goes from the metabolism of microbiota to the metabolism of alga. These methods answer biologist question according to specific data (taxonomic affiliations form metabarcoding, genomes, Mass-to-Charge ratio). To answer these questions I have developed methods combining Knowledge engineering, Comparative Genomics and Systems Biology to infer and make prediction on the metabolism of microbial community, alga and taxonomic groups.

Softwares

Metage2Metabo: Identify key species in community by using metabolic complementarity from either genomes (in GenBank format) or metabolic networks (in SBML). Also other tools were developed with Metage2Metabo:

  • emapper2gbk: Conversion of eggnog-mapper output files into a GenBank files (that can be used with Metage2Metabo).
  • mpwt: Multiprocessing implementation of Pathway Tools to reconstruct draft metabolic networks in large-scale.

PathModel: Prototype using the Metabolic Pathway Drift assumption to infer alternative metabolic pathway from a reference metabolic pathway and known molecules (or mass-to-charge ratio) from metabolomics.

AuCoMe: Automatic comparison of metabolism for a group of organisms. By using heterogeneously annotated genomes from public databases, AuCoMe reconstructs homogenized metabolic networks by using sequence comparison.

EsMeCaTa: Estimating Metabolic Capabilities for Taxonomic Affiliations. From a taxonomic affiliations, EsMeCaTa searches for proteome on UniProt then clusters them with MMseqs to find the set of shared protein clusters among the protein and then extracts their annotations. By combining with Pathway Tools, it is then possible to have metabolic networks for a taxon.
