  1. Mean ± SEM are shown and highlighted in boldface for those families with significant differences after correction for False Discovery Rate (q < 0.05).
  2. *Note that the family Hyphomicrobiaceae contains the genera Gemmiger, which shows high 16S rRNA gene sequence homology to members of the Ruminococcaceae family (Firmicutes), and may thus be taxonomically misplaced.
