Simplified gut communities growing in bioreactors grow and metabolize reproducibly, with only moderate variations, even when individual members of the community are absent!
Microbe of the episode
Microbe of the episode: Citrobacter virus Merlin
In this study, a simplified community of only 14 species is grown repeatedly in bioreactors, and one species at a time is left out of the community to see what will change in its absence. This reveals effects different species have on the overall growth, carbon source consumption, and production of various metabolites relevant to gut health. Some microbes have large effects, but none of them appears to be crucial for the overall function and stability of the community.
