Abstract:: Aquatic fecal contamination from non-point sources impairs environmental health and serves as a vehicle for transmission of waterborne disease, resulting in economic losses worldwide. Accurate methods of diagnosing fecal pollution and its source are needed to prevent human exposure, remediate pollution, and reduce economic impacts. In order to obtain this...

Creator:: Doughty, David M.
Abstract:: The regulation of monooxygenase enzymes has been demonstrated in bacteria that grow on methane and long chain-length alkanes (>C10). Less is known about monooxygenase regulation in short chain alkane oxidizing bacteria that grow on intermediate chain-length alkanes C2-C10. This dissertation focuses on the regulation of butane monooxygenase (BMO) expression and...

Creator:: Starkenburg, Shawn R.
Abstract:: The chemolithoautotrophic nitrite oxidizing bacteria (NOB) participate in the biogeochemical cycling of nitrogen by catalyzing and conserving energy from the oxidation of nitrite (NO₂-) to nitrate (NO₃-) via a nitrite oxidoreductase (NXR). The main objective of this work was to comparatively annotate and analyze the genome sequences of Nitrobacter winogradskyi...

Creator:: Kim, Eugene
Abstract:: Cereal and commercial grass-seed straws are abundant plant biomass materials that are currently being considered for application in industrial processes aimed at the production of biofuels, biomaterials, and biochemicals. The carbohydrate fraction of these straws is of particular interest in this context due to its chemical functionality and relative ease...

Creator:: Bottoms, SueAnn I.
Abstract:: Research suggests that long-term participation in professional development is critical in helping teachers meet the increasing demands of reform efforts and changing practice (Gallucci, 2003; Darling-Hammond, 1995; Little, 1993). Understanding the influence that participation in a community of teachers as a community of practice may have on teachers’ professional growth...

Creator:: Skinner, Kristin M.
Abstract:: Graphium sp., a eukaryotic alkanotroph, is able to oxidize small-molecular weight gaseous n-alkanes, diethyl ether and the branched ether, methyl tert butyl ether (MTBE). However, information regarding the biochemistry of fungal-mediated alkane and ether metabolism is limited, and questions regarding the identity of alkane oxidation catalysts and the genetic underpinnings...
