Figure 2. MF consumption shifts bile composition toward greater proportion of taurocholate and promotes growth of B. wadsworthia (Bw) in vitro.
A. Chemical structures of taurocholic and glycocholic acids, illustrating the distinctive sulfur moiety with taurine conjugation. b. Gall bladder aspirates from SPF IL10−/− mice consuming LF, PUFA or MF for 5 weeks were analyzed by HPLC and mass spectrometry to determine bile composition. c. The gallbladder aspirates were then added to the growth media of Bw at time=0. Normal Bw growth media contains taurine, however added taurine in this media was removed. Bile was added at 1% of media and optical density was recorded every hour for 24 hrs. At 4 hours post-innoculation, Bw growth began to rapidly increased in the media containing bile from MF-fed mice.
