Oxygen consumption by bacteria along the intestinal tract. (A) Proportion of the four major bacterial phyla comprising the gut microbiota in luminal and mucosal samples throughout the length of the intestinal tract, as determined by 16S rRNA gene tag sequencing. (B) Total bacterial abundance in luminal and mucosal samples, as quantified by real-time qPCR of 16S rRNA gene copies. (C) Estimated oxygen consumption rate by luminal and mucosally adherent bacteria along the intestinal tract.
