Synthetic Biology Guides Biofuel Production

Figure 1

Metabolic schematic for biofuel production. Biofuel production pathways for traditional fermentative processes (grey), nonfermentative higher chain alcohols (green), isoprenoid fuels (blue), and fatty acid fuels (red) from central metabolism. Abbreviations: 2 KB (2-ketobutyrate), 2 KIV (2-ketoisovalerate), 2KIC (2-ketoisocaproate), 2 MB (2-methyl-1-butanol), 3 MB (3-methyl-1-butanol), ACP (acyl carrier protein), CoA (coenzyme A), DMAPP (dimethylallyl diphosphate), FAEE (fatty acid ethyl ester), FAME (fatty acid methyl ester), FFA (free fatty acid), G3P (glyceraldehyde-3-phosphate), IPP (isopentyl diphosphate), and OAA (oxaloacetate).
