Application Of Synthetic Biology For Increasing Anaerobic Biodiesel Production In Escherichia Coli, Michael Christopher Wierzbicki
Masters Theses
The ever-increasing demand for transportation biofuels requires new and novel approaches to solve the complexities associated with efficient biofuel production. Ethanol, the most common biofuel, has physical limitation associated with difficulty of separations and issues with water contamination and as such is not a long-term transportation fuel solution. (Lou & Singh, 2010; Wheals, Basso, Alves, & Amorim, 1999) Biodiesel is seen as a possible alternative to ethanol due to its hydrophobicity and also has comparable energy density and cetane number to its petroleum derived counterpart. (Kalscheuer, Stölting, & Steinbüchel, 2006) Because of feedstock limitations, biodiesel produced from vegetable oils is …

Doctoral Dissertations
Biodiesel fuel has increased in popularity in recent years as an alternative fuel choice, but there are concerns related to the impact it will have on diesel engines and aftertreatment systems relative to conventional diesel fuel. One major concern is the presence of sodium (Na) in finished biodiesel fuel due to the use of Na-hydroxyl as a liquid-phase catalyst during biodiesel synthesis. The current study focuses on determining the impact of biodiesel-based Na on the performance and materials characterization of diesel aftertreatment devices including lean NOx traps (LNT), diesel oxidation catalysts (DOC), diesel particulate filters (DPF), and Cu-zeolite selective catalytic …
