From: Feeding Drosophila gut microbiomes from young and old flies modifies the microbiome

Microbial supplementation positively affects lifespan. Lifespan of D. melanogaster males is positively affected by supplementation with bacterial suspension from both old and young flies as compared to sucrose control (p = 0.034 and p = 0.0087, log-rank). No difference is observed between the two microbial supplements (p = 0.5, log-rank) (n = 80).
