Screening For Cry Proteins With Unique Receptors In Fall Armyworm (Spodoptera Frugiperda) And Corn Earworm (Helicoverpa Zea), Aria C. Deluna Aug 2021

Screening For Cry Proteins With Unique Receptors In Fall Armyworm (Spodoptera Frugiperda) And Corn Earworm (Helicoverpa Zea), Aria C. Deluna

Masters Theses

Bacillus thuringiensis (Bt) proteins have been the primary method for controlling Lepidopteran pests of corn and cotton over the past 20 years, due to their effectiveness and high level of target specificity. The fall armyworm (Spodoptera frugiperda) developed resistance to Cry1f, a Bt protein produced by both corn and cotton, within three years of registration in Puerto Rico. The evolution of resistance in pest insects poses as a threat to food safety as well as potentially resulting in economic losses of over $1 billion. The majority of Cry proteins follow a three domain (I to III) …


Switchgrass Extractives Have Potential As A Value-Added Antimicrobial Against Plant Pathogens And Foodborne Pathogens, Alexander Ian Bruce Dec 2016

Switchgrass Extractives Have Potential As A Value-Added Antimicrobial Against Plant Pathogens And Foodborne Pathogens, Alexander Ian Bruce

Masters Theses

Panicum virgatum (switchgrass), a perennial grass native to North America, is a leading biomass feedstock candidate for the manufacture of cellulosic ethanol. Switchgrass is considered a viable option for biofuel production due to its cheap production cost and ability to grow on marginal land. Biofuel derived from switchgrass has been shown to be very energy efficient, producing 540% more renewable energy versus nonrenewable energy expended. Switchgrass-derived biofuel is also estimated to have greenhouse gas emissions that are 94% lower than emissions from gasoline (Schmer et al 2008). Biofuels are created through biochemical processes that utilize various enzymes and microorganisms for …
