In Ian Lipkin et al 2017 study, low bacteroides caccae was reported (on average). [Index to all posts on Study].
- ” the elevated biotin level was due to an alteration in metabolism related to biotin synthesis by Bacteroides caccae in this mouse model.” So low Vitamin B7
- Fermentation of pectin and glucose, and activity of pectin-degrading enzymes in the rabbit caecal bacterium Bacteroides caccae .
- “Effects of apples and specific apple components on the cecal environment of conventional rats: role of apple pectin “The observed increase in butyrate, which is considered beneficial for gut health, correlated with an increase in the Clostridia XVIa cluster that harbors many butyrate producing species. The evidence thus suggests that apples have a health-promoting effect on the rat intestinal microbiota, and that this effect is mainly explained by the presence of pectin in the apples. However, there are lots of cautions to be taken when extrapolating data from animal experiments to humans, and it should be kept in mind that rats metabolize the ingested apple components differently from humans.”
I almost gave up on finding more information until I found the diagram below (which also contains Faecalibacterium prausnitzii which is also low!)

The best growth medium are:
- Xylose Amazon
- Ribose (shown to help CFS in studies) Amazon
- Rhamnose – very expensive
- N-actylneuraminic acid
- Glucuronic acid
- Arabinose Amazon
- Mannose – Amazon
- Glucose (which also is liked by two other low bacteria)
- Chondroitin sulfate
- Pectic galactan (potatoand lupin)
It looks like Inulin and Ribose are again on our list, and many of the above are also available on Amazon etc.
