Abstract:
As the consequences of climate change become apparent, metabolic engineers and synthetic biologists are exploring sustainable sources for transportation fuels. The design and engineering of microorganisms to produce bio-gasoline and other biofuels from renewable feedstocks can significantly reduce dependence on fossil fuels as well as lower the emissions of greenhouse gases. A significant amount of research over the past two decades has led to the development of microbial strains for the production of advanced fuel compounds. Crucial to these efforts are robust methods to quantify the amount of the biofuel compound being produced as well as the other metabolites that might be present during fermentation. Here, we provide a protocol for the quantification of branched-chain alcohols, specifically isobutanol and isopropanol, using high-performance liquid chromatography (HPLC).

In aerobic organisms, pyruvate is metabolized via the citric acid cycle to produce reduced coenzymes NADH and FADH2. These coenzymes are then oxidized in the electron transport chain to produce ATP and, in the process, regenerate the NAD+ and FAD. As seen in some cell types and organisms, fermentation...
