Elucidating Mechanisms And Genotypes Underlying Robust Phenotypes In Yarrowia Lipolytica, Caleb M. Walker
Elucidating Mechanisms And Genotypes Underlying Robust Phenotypes In Yarrowia Lipolytica, Caleb M. Walker
Doctoral Dissertations
Robustness is an important phenotype for bioenergy microbes to acquire but is difficult to engineer. Hence, tools for engineering microbial robustness are critical to unlock novel phenotypes for innovative bioprocessing strategies. The oleaginous yeast, Yarrowia lipolytica, is an exceptionally robust microbe that can tolerate stressful environments, assimilate a wide range of substrates, and produce high-value chemicals. In this doctoral dissertation, the impacts of systems biology and metabolic engineering to reveal mechanisms and identify genotypes- underlying robust phenotypes are addressed.
The first approach employs adaptive laboratory engineering to generate a platform strain by which to study superior robust mechanisms. This …

Doctoral Dissertations
Metabolic engineering and synthetic biology enable controlled manipulation of whole-cell biocatalysts to produce valuable chemicals from renewable feedstocks in a rapid and efficient manner, helping reduce our reliance on the conventional petroleum-based chemical synthesis. However, strain engineering process is costly and time-consuming that developing economically competitive bioprocess at industrial scale is still challenging. To accelerate the strain engineering process, modular cell engineering has been proposed as an innovative approach that harnesses modularity of metabolism for designing microbial cell factories. It is important to understand biological modularity and to develop design principles for effective implementation of modular cell engineering. In this …
