In the human gut microbiota, small ecosystems called microbial guilds exists. These guilds share a metabolic process.
By using graph theory, we were able to show that a higher species richness within these guilds is directly linked a higher efficiency of the metabolic process and redundancy.
This work provides a first step towards a rational approach with respect to microbiota intervention.
