Development Of Novel Crispr-Based Methods For Transcriptional Control Over Bacterial Gene Expression, Katia Tarasava
Materials Science & Engineering Graduate Theses & Dissertations
One of the challenges of the 21st century is creating a sustainable economy that is able to serve the needs of a growing population with the decreasing supply of natural resources. In addition to alternative energy sources, renewable economy concerns production of materials and chemicals. The chemical and polymer industries rely heavily on petroleum for manufacturing consumer goods. Many of these chemicals can be produced from renewable resources using microorganisms. However, the amounts produced are often not enough to make the process commercially viable. By rewiring cellular metabolism and regulation, it is possible to redirect metabolic flux to increase the ...
Engineering Bacterial Gene Expression: Applications Towards Biofuels And Antibiotic Resistance, Peter Britton Otoupal
Chemical & Biological Engineering Graduate Theses & Dissertations
Nature is rarely static. Organisms live in diverse and stressful environments that necessitate rapid response strategies for survival. Microorganisms have responded to this by evolving bet-hedging, wherein they exhibit constitutively heterogeneous gene expression to maximize fitness across numerous background. The goal of this thesis is to “hijack” this phenomenon using novel gene expression engineering techniques to alter how bacteria respond to their environments, in order to address pressing societal concerns.
This begins with a systematic exploration of how bacterial gene expression naturally responds to antibiotics and biofuels. This reveals promising gene candidates for targeted manipulation, for which a library of ...
