The Role Of Endophytes In Conferring Salinity Tolerance In Prairie Cordgrass And The Winter Wheat Mint Variety, Jeffery Bartel
The Role Of Endophytes In Conferring Salinity Tolerance In Prairie Cordgrass And The Winter Wheat Mint Variety, Jeffery Bartel
Electronic Theses and Dissertations
Prairie Cordgrass (PCG) Spartina pectinata is a native grass to North America that survives saline conditions, can be harvested multiple times in a year, and can be used as biofuel. Endophytes are bacteria that reside in plant tissues and often have growthpromoting capabilities. They can assist plants by obtaining nutrients by improving the tolerance of plants against a broad range of stresses, such as plant pathogens, viruses, flooding, drought, acids, or bases. PCG can survive ocean levels of salinity. Endophytes that naturally bond with PCG may not only be able to not only help PCG but be transferred to other …
Development Of Heterogeneous Catalysts For Upgrading Biomass Pyrolysis Bio-Oils Into Advanced Biofuels, Shouyun Cheng
Development Of Heterogeneous Catalysts For Upgrading Biomass Pyrolysis Bio-Oils Into Advanced Biofuels, Shouyun Cheng
Electronic Theses and Dissertations
The massive consumption of fossil fuels and associated environmental issues result in an increased interest in alternative resources such as biofuels. The renewable biofuels can be upgraded from bio-oils that are derived from biomass pyrolysis. Catalytic cracking and hydrodeoxygenation (HDO) are two most promising bio-oil upgrading techniques for biofuel production. Heterogeneous catalysts are essential for upgrading bio-oil into hydrocarbon biofuel. Although some progresses have been made, the cost and effectiveness of catalysts still remain challenges. The main objective of this study was to develop efficient heterogeneous catalysts for upgrading bio-oils into advanced hydrocarbon biofuel with low costs. In catalytic cracking, …
Enhancing The Industrial Potential Of Filamentous Cyanobacteria, Tylor J. Johnson
Enhancing The Industrial Potential Of Filamentous Cyanobacteria, Tylor J. Johnson
Electronic Theses and Dissertations
The objectives of this project were to improve the industrial potential of filamentous N2-fixing cyanobacteria by increasing its biofuel tolerance, and to evaluate the economic feasibility and environmental impacts of a theoretical, cyanobacteria-based biofuel production facility. To develop a method to quantify filamentous cyanobacteria in dilute culture media, a dual-stained fluorescence assay was evaluated. While the viable cell stain (SYTO® 9) was accurate, the non-viable cell stain (propidium iodide) also bound to viable cells. Additional non-viable cell stains were evaluated, but none were accurate at quantifying viability. Thus we concluded that the viable cell stain SYTO® 9 is a reliable …
