Construction of a model organism for performing calcium carbonate precipitation in a porous media reactor

Creator:: Kaufman, Megan J.
Abstract:: Aquifers are an important storage location and source of fresh groundwater. They may become polluted by a number of contaminants including mobile divalent radionuclides such as strontium-90 which is a byproduct of uranium fission. A method for remediating such divalent radionuclides is sequestration through co-precipitation into calcium carbonate. Calcium carbonate...

Effects of physiological state upon nitrosoguanidine-mediated allelic recombination in Saccharomyces cerevisiae

Creator:: Buettner, Michael John
Abstract:: Saccharomyces cerevisiae strain XS-380, a. heteroallelic diploid strain, carries six genetically analyzed loci on the left arm of chromosome VII. Nitrosoguanidine (NMG) at low concentrations was observed to cause allelic recombination (either mitotic recombination or gene conversion) of the heteroallelic loci with low lethality. The NMG-inducible heteroallelic system was used...

Full Text:: . Obviously before such experiments could be attempted, a well-defined genetic map had to be constructed in

Understanding chlamydial biology through genome sequencing and comparative genomics

Creator:: Jeffrey, Brendan
Abstract:: The human pathogen Chlamydia trachomatis displays different phenotypes between serovars both in vivo and in vitro. The study of chlamydial biology has been hampered by the lack of a tractable genetic system. Here, chlamydial isolates with known phenotypes as well as strains generated though recombination were fully sequenced to address...

Characterization of the interaction between Mycobacterium avium subsp. paratuberculosis and bovine epithelial cells in culture and identification of invasion-associated genes by transposon mutagenesis

Creator:: Patel, Dilip
Abstract:: Mycobacterium avium subsp. paratuberculosis (MAP) is a cause of Johne's disease (JD) in cattle and other ruminants. MAP infection in the bovine host is not well characterized. It is assumed that crossing the bovine intestinal mucosa is important for MAP to establish infection. MAP's ability to infect bovine epithelial cells...

Macrophage infection with wild-type Mycobacterium avium or isogenic attenuated PPE mutant revealed differences in gene expression and mycobacterial vacuole proteins

Creator:: Jha, Samradhni
Abstract:: Mycobacterium avium is a ubiquitous environmental organism found in water and soil. It can cause disease in patients with pre-existing pulmonary conditions, immunocompromised patients with the most prevalent being AIDS patients, as well as apparently healthy people. Studies have indicated that, upon macrophage uptake, Al. avium prevents phagosome-lysosome fusion, thus...

An investigation of carbon and nitrogen metabolism through a genomic analysis of the genus Nitrobacter

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...

Identification of an aerotaxis transducer in Vibrio cholerae

Creator:: Boin, Markus A.
Abstract:: The ability to move towards favorable environmental conditions, called chemotaxis, is common among motile bacteria. In particular aerotaxis has been extensively studied in Escherichia coli. Three putative aer gene homologs were identified in the V. cholerae genome designated VCAer-1 (VC0512) VCAer-2 (VCA0658), and VCAer-3 (VCA0988). Deletion analyses indicated that only...
Resource Type:: Masters Thesis
