Figure 4. Investigation of the microbial genetic traits involved in SCFAs and vitamin biosynthesis. The heat map illustrates the genome-level presence (colored box) or absence (black box) of genes involved in the biosynthesis of organic acids (violet) and B-group vitamins (light blue). These investigations are based on the search for the gene encoding the final enzyme in the pathway, which is specified through the EC number reported on the first row. SCFAs: Short-chain fatty acids; EC: Enzyme Commission.
