Analysis Of The Effect Of Corrosion On The Surface Chemistry Of Mild Steel Exposed To Biofuel, Timothy D. Plourde
Analysis Of The Effect Of Corrosion On The Surface Chemistry Of Mild Steel Exposed To Biofuel, Timothy D. Plourde
Theses and Dissertations
The use of biofuels in society is steadily becoming more prevalent. Through this proliferation a concern regarding the role of the fungus Byssochlamys nivea in microbially induced corrosion has surfaced. Through the use of X-ray Photoelectron Spectroscopy (XPS) and Scanning Electron Microscope (SEM) technology, this thesis focused on attempting to determine what effect, if any, Byssochlamys nivea has on the corrosion of mild steel. For this analysis, samples were placed in environments that simulated the conditions of fuel tanks containing the biofuel B20, water, and spores of Byssochlamys nivea for varying lengths of time. However, due to a variety of …

Thermotoga maritima is an anaerobic hyperthermophilic bacterium known for its high amounts of hydrogen (H2) production. In the current study, the kinetic modeling was applied on the engineered strains of T. maritima that surpassed the natural H2 production limit. The study generated a kinetic model explaining H2 overproduction and predicted a continuous fermentation system. A Leudking-Piret equation-based model predicted that H2 production by Tma200 (0.217 mol-H2 g–1-biomass) and Tma100 (0.147 mol-H2 g–1-biomass) were higher than wild type (0.096 mol-H2 g–1 -biomass) with reduced rates of maltose utilization. …
