Sugar, butyrate, and bacterial growth

Caption

This schematic illustrates the growth or “fitness” of various Bacteroides species exposed to different sugars, alone and with the bacterial metabolite butyrate. The strains in green on the right are the most fit and best able to tolerate butyrate, while those shown in red die off. The fitness profiles vary from species to species and from sugar to sugar.
