Focus on Microbial Ecology Modelling at the NEM days meeting in Rennes

Published: May 6, 2025 by FME Lab

The French NEM (Nutrition & Microbial Ecosystems) network hold its annual meeting this last two days (5th – 6th of May) in Rennes. Julien Tap, researcher from the FME lab presented the first results of his Ferment du Future SynthPlex project and how Engineering food microbial consortia can be performed using microfermentors to reveal strain epistasis. With the Support of Holoflux and Digit-Bio INRAE Metaprogram, He also co-organized with Guillaume Gautreau from the MaIAge Unit a specific workshop on modelling of microbial ecosystems.

In this session, Bastien Renard and Ayité Adama-Hondegla, PhD students involved in the #DominoEU project, presented their pioneering work in the design of microbial consortia for plant-based fermented foods using genome-scale modelling. The session resumed with additional strategies and perspectives presented by Maxime Lecomte (INRAE, STLO) and Daniel-Rios Garza (INRAE, Prose). Altogether, they showed that despite the promises that GSM can bring, many challenges remains to be overcome. A very interesting scientific field to follow in the near future.

During NEM days, Microbiome Modelization specific sessions program was:

Bastien Renard: Design of microbial solutions for healthy and sustainable innovative fermented cereal beverages
Ayite Adama-Hondegla: Microbial community assembly and metabolic diversity in a legume-based matrix
Maxime Lecomte: Revealing the dynamics and mechanisms of bacterial interactions in cheese production with metabolic modelling
Daniel-Rios Garza: Towards the Development of Closed-Loop Microbiome Controllers

From food spontaneous fermentations to food designed consortia

The FME lab communicates about the links between the microbiome, nutrition and health.

On Thursday 27 November, the FME lab took part in the Food System Microbiomes Conference in Wageningen during the session dedicated to the connections between microbiomes, nutrition and health. The session was co-chaired by Stéphane Chaillou (INRAE, Micalis) and Prof. Christophe Courtin (KU Leuven), and provided an opportunity to showcase advances from two major European projects: DOMINO and HealthFerm.

Understanding How Fermented Foods Shape Health Insights From a New PIMENTO Review

A new scoping review published in Frontiers in Nutrition¹ as part of the COST Action PIMENTO initiative provides a comprehensive assessment of what is currently known about the health effects of fermented foods in specific human populations. This work reflects a substantial collective effort. We conducted an extensive and rigorous screening of the scientific literature, reviewing and selecting studies across many categories of fermented foods and health outcomes.
