Discovery of potential genes contributing to the biosynthesis of short-chain fatty acids and lactate in gut microbiota from systematic investigation in E. coli

Synthetic pathways of SCFAs and lactate in bacteria. The genes shown in blue or dashed line are described in this paper. Most genes were studied in E. coli strains. The ptb-buk gene does not exist in E. coli but in some Clostridium strains. DHAP: dihydroxyacetone-phosphate; AcCoA: acetyl-CoA; BuCoA: butyryl-Co
