  1. Data are mean log10 16S rRNA GC mL−1 fermentation effluent from 6 h after CD vegetative cells inoculation (log10 9.8 cfu in 250 mL volume PC reactor) and during the following 16 days. Samples were analyzed in duplicate. The detection limit of qPCR of CD was log10 4.4 GC mL−1
  2. PC, proximal colon; TDC, transverse-distal colon; CD, C. difficile; ND, not detected
