WORKSHOP

METABOLIC MODELS APPLIED TO MICROBIOMES

Antony, 12-14th of March 2025

About the Workshop

Metabolism is the unifying feature of life on our planet. Every microbe harbors a series of integrated biochemical reactions encoded in its genome that generate energy and supply the essential building blocks for cell assembly. By examining metabolism, we can understand microbial ecosystems—microbiomes—in mechanistic terms, as the flow of energy and matter between the environment and cells.

The complete set of genome-encoded enzymes offers deep insight into a microbe’s phenotypic landscape. It reveals the organism’s potential food sources, its biochemical pathways, and how these processes work together to build biomass. Within a community, these enzymes also highlight molecular cross-feeding, cooperation, and competition for valuable resources among coexisting metabolic strategies.

In this workshop, we will explore state-of-the-art approaches to reconstruct genome-scale metabolic models from complete genome sequences or metagenome-assembled genomes (MAGs), evaluate their quality, and apply computational methods to interrogate the structure and function of microbiomes from the perspective of reconstructed microbial metabolisms.

Please enroll by filling out the form below and bring a laptop to follow the practicals. The workshop will take place in the Salle Seine. Batiment Lavosier at INRAE/PROSE in Antony

Session 0: Preparing for the Workshop

Before March 12

Install the necessary packages in your laptop

Session 1: Reconstructing and manipulating GSMMs

12th of March 2025

2-5 p.m.

In this session we will learn how to work with COBRApy, reconstruct a draft genome-scale metabolic model starting from a fasta file, use the modelSEED pipeline

Gapfilling GSMM with DNNGIOR and building your own training-testing dataset

13th of March 2025

10 a.m. - 12 noon

In this session, we will use the deep learning-based approach DNNGIOR, combined with fast gapfilling to complete draft models so that they are able to produce biomass.

Answering biological questions with GSMMs

13th of March 2025

2-5 p.m.

In this session we will use a suite of computational tools to explore scientific questions using genome-scale metabolic models. Then we will work on examples provided by some of the participants.
