Synthetic Biology For Autotrophic And Heterotrophic Production Of Ethanol, Nathanael Braselton

Electronic Theses and Dissertations

Growing energy demand and rising levels of greenhouse gases has put massive strain on the global environment. Alternatives to fossil fuels are being developed in an attempt to curb climate change. Biotechnology has made large strides in order to create a completely renewable energy source by genetically modifying microbes to produce biofuels and other “green” high value compounds. In this thesis project, (1) E. coli ATCC9637 (E. coli W) was genetically modified to produce bioethanol from beet juice which contains mainly sucrose. The ethanol productivity by engineered E. coli W was 18.8 mg/L/H/OD₆₀₀.
