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 …
Trypanosoma Brucei Mitochondrial Dna Polib Cell Cycle Localization And Effect On Polic When Polib Is Depleted, Sylvia L. Rivera
Trypanosoma Brucei Mitochondrial Dna Polib Cell Cycle Localization And Effect On Polic When Polib Is Depleted, Sylvia L. Rivera
Masters Theses
Trypanosoma brucei is the causative agent of Human African Trypanosomiasis (HAT), also known as African sleeping sickness. T. brucei is unique in several ways that distinguish this organism from other eukaryotes. One of the unique features of T. brucei is the organism’s mitochondrial DNA, which is organized in a complex structure called kinetoplast DNA (kDNA). Since kDNA is unique to the kinetoplastids, kDNA may serve as a good drug target against T. brucei. Previews studies have shown that kDNA has 4 different family A mitochondrial DNA polymerases. Three of these mitochondrial DNA polymerases (POLIB, POLIC, and POLID) are essential …
Distribution Of Enterotoxigenic Clostridium Perfringens Spores In U.S. Retail Spices, Chi-An Lee
Distribution Of Enterotoxigenic Clostridium Perfringens Spores In U.S. Retail Spices, Chi-An Lee
Masters Theses
246 samples of bulk and packaged spices from retail stores in the western, southeastern, southern, midwestern, and northeastern areas of the U.S. were examined for the presence of Clostridium -perfringens. Isolates were checked for the presence of the lecithinase gene (cpa) and enterotoxin genes (cpe) by PCR. Enterotoxin formation during sporulation was investigated using the Oxoid Toxin Detection Kit. Forty-three confirmed isolates (from 17% of total samples) were cpa-positive. Of those, 27 were cpe-positive. Together, levels of C. perfringens spores ranged from 3.6-2400/gm. The amount of enterotoxin in cell extracts ranged from …
