Figure 4

Heat map of relative abundance of taxa with significant differences at the genus level for SCFAs-producing bacteria, SCFAs-related bacteria (bacteria that grow on SCFAs, bacteria whose presences are directly proportional to the level of SCFAs, or close relatives of SCFA-producing bacteria), and bacteria unrelated to SCFAs, in the cecal microbiota compositions comparing long-term powdered diet-fed mice and control diet-fed mice (mean relative abundance > 0.1%). The abundance of each genus is plotted in a brown–blue color scale. The brown and blue colors indicate high and low abundance, respectively. n = 8 per group.
