Natural bacterial ecosystems

Eugenio Cinquemani, Alexandre Dawid, Hidde de Jong, Delphine Ropers

Microbial communities in the environment contain thousands or even millions of species per sample. This diversity includes bacteria, archaea, fungi, and viruses. Microorganisms within the community interact through cooperation, competition, predation, or chemical signalling. These communities are also closely linked to their environment, to which they adapt and which they shape (nitrogen fixation, carbon cycle, etc.). We model the dynamics of community growth to unravel the complexity of interactions within the community and with its environment, particularly the environmental impact of the community.
