Switchgrass Extractives Have Potential As A Value-Added Antimicrobial Against Plant Pathogens And Foodborne Pathogens, Alexander Ian Bruce
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 …
Multilayered Regulation Of The Type I Toxin Zoro In Ehec, Jia Wen
Multilayered Regulation Of The Type I Toxin Zoro In Ehec, Jia Wen
Doctoral Dissertations
A bacterial type I toxin-antitoxin system contains two genes: one encodes a small toxic protein and the second, a small regulatory RNA (sRNA) that inhibits toxin production. To date, very few type I loci have been described thoroughly in regards to the regulation of toxin and the function of the toxin at endogenous levels. In this study, I demonstrated that the zor-orz locus of Escherichia coli O157:H7 is composed of two highly homologous type I toxin-antitoxin systems: zorO-orzO and zorP-orzP. The zor genes encode the toxins and the orz genes encode the antitoxin sRNAs. Overexpression of zorO is toxic …
