Figure 2: Metabolic schematic for direct photosynthetic biofuel production. Biofuel production pathways for traditional fermentative processes (grey), nonfermentative higher chain alcohols (green), isoprenoid fuels (blue), and fatty acid fuels (red) from CO2 through photosynthesis. Abbreviations: 2 KIV (2-ketoisovalerate), 3PG (3-phosphoglycerate), ACP (acyl carrier protein), CoA (coenzyme A), DMAPP (dimethylallyl diphosphate), G3P (glyceraldehyde-3-phosphate), PSI (photosystem I), PSII (photosystem II), and RuBP (ribulose-1,5-bisphosphate).
