Metabolic Modeling Of Bacterial Co-Cultures For Co-To-Butyrate Conversion In Bubble Column Bioreactors, Naresh Kandlapalli Oct 2021

Metabolic Modeling Of Bacterial Co-Cultures For Co-To-Butyrate Conversion In Bubble Column Bioreactors, Naresh Kandlapalli

Masters Theses

One of the most promising routes to renewable liquid fuels and chemicals is the fermentation of waste carbon by specialized microbes. Commercial development of gas fermentation technology is underway but many fundamental research problems must be addressed to further advance the technology towards economic competitiveness. This thesis addresses the important problem of developing integrated metabolic and transport models that predict gas fermentation performance in industrially relevant bubble column reactors. The computational models describe the conversion of CO-rich waste streams including synthesis gas to the platform chemical butyrate. The proposed modeling approach involves combining genome-scale reconstructions of bacterial species metabolism with …

Metabolic Modeling Of Gas Fermentation For Renewable Fuel And Chemical Production, Xiangan Li

Doctoral Dissertations

Gas fermentation has emerged as a technologically and economically attractive option for producing renewable fuels and chemicals from carbon monoxide (CO) rich waste streams. As compared to traditional catalyst technologies, microbial systems have several advantages including operation near ambient temperature and pressure, high conversion efficiencies, robustness to gas impurities and high product yields that have motivated both fundamental research and commercial development. While microbial production of high-value products from waste gases is challenging because wild-type strains capable of gas consumption tend to synthesize these products at low yields, strategy like metabolically engineering the gas fermenting acetogens have been studied to …
