Gut microbiota composition of C. elegans and bacterial effects on host physiology. a, Gut microbiota composition of C. elegans fed HQbiome. b, Gut microbiota composition of C. elegans fed HQbiome-1. c, Gut microbiota composition of C. elegans fed HQbiome-3 in day 5 of adulthood. d, C. elegans egg-laying time fed HQbiome, HQbiome-1, HQbiome-2, and HQbiome-3, respectively. n = 3 independent experiments, each scoring 35 animals. e, C. elegans mean lifespan fed HQbiome, HQbiome-1, HQbiome-2, and HQbiome-3, respectively. n = 80–108 worms per bacterial isolate. Source data of d and e are presented in Additional file 6. P values in d and e were generated from one-way ANOVA, followed by Tukey’s post hoc test. *P  <  0.05; **P <  0.01; ***P  <  0.001; ****P  <  0.0001. Boxes indicate the first and third quartile of counts, lines in boxes indicate median values, and whiskers indicate 1.5 × IQR in either direction. f, C. elegans survival curves fed HQbiome, HQbiome-1, HQbiome-2, and HQbiome-3, respectively. n = 80–108 worms per bacterial isolate. Log-rank test was used for the assessment of significance
