Antibacterial Activity And Chemical Characterization Of Resin From Sciadopitys Verticillata (Thunb.) Siebold And Zuccarini, David Ira Yates
Doctoral Dissertations
Sciadopitys verticillata produces white viscous resin that is unique among the conifers. This research investigated effects of resin on bacteria from different ecological niches and the chemical composition of the resin. Each bacterial species was evaluated separately for response to winter- and summer-collected resins. Exposure to winter-collected resin reduced numbers of colonies of Bacillus cereus, Erwinia amylovora, Agrobacterium tumefaciens, and Escherichia coli and increased numbers of Xanthomonascampestris, Pseudomonas fluorescens, and Pseudomonas syringae. Summer-collected resin affectedpopulation growth of two bacterial species; population counts of E. amylovora decreased and those of P. fluorescens increased. Selected strains of …
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 …
