471238 Technoeconomic Analysis of Conversion of Corn Fiber to Ethanol Using Engineered Thermophilic Bacteria
In the main part of this presentation, we present a technoeconomic analysis of thermophilic conversion of corn fiber. In particular, we analyze the parametric impact of key performance parameters on payback period, including solubilization yield (fractional sugars solubilized), fermentation yield (ethanol produced per sugar fermented), and ethanol titer. Integrated separation of a dilute ethanol stream resulting from thermophilic corn fiber fermentation with a larger flow of more concentrated ethanol produced from corn starch fermentation is analyzed. It is concluded that economic viability can be achieved at lower ethanol titer in a bolt-on configuration as compared to a stand-alone configuration. Results support corn fiber conversion as a low-capital/high return point-of-entry for industrial application of engineered thermophilic microbes.
