Predatory bacteria as members of human microbiomes and their impact on gut diversity and homeostasis

Johannes Zimmermann, Julia Johnke

This study identifies predatory bacteria (BALOs) in the human gut microbiome, showing they enhance microbial diversity and may contribute to gut homeostasis by controlling harmful bacteria.

Predatory bacteria impact C. elegans life-history traits by modulating microbiota community dynamics and thereby vitamin B12 availability

Janna Wülbern, Levke Hansen, Catherine C. Bannon…·Julia Johnke

This study shows predatory bacteria alter C. elegans microbiota, increasing vitamin B12 availability, which extends lifespan by suppressing a detoxification pathway.
