Inhibition of the ammonia oxidizing bacteria Nitrosomonas europaea by the emerging contaminant triclosan

Creator:: Hughes, Jamie L.
Abstract:: Identifying the inhibition of ammonia oxidizing bacteria (AOB) by emerging organic contaminants is crucial due to the importance of AOB in wastewater treatment, the widespread use of antibacterial agents such as triclosan (TCS) in consumer products, and the sensitivity of N. europaea to inhibitors. Triclosan inhibition of nitrification by AOB...

Evaluation of peptide phosphorodiamidate morpholino oligomers as a novel antibiotic therapy

Creator:: Kaller, Margo
Abstract:: Peptide-phosphorodiamidate morpholino oligomers (PPMOs) are synthetic DNA mimics that bind and silence gene targets. Through designing PPMOs that silence essential or resistance genes in pathogens, these antisense oligomers could be utilized as novel antimicrobials. Towards this end, my thesis employed minimum inhibitory concentration assays (MICs) to identify PPMOs capable of...

Significance of pigments in radiation resistance of Micrococcus radiodurans

Creator:: Krabbenhoft, Kenneth Louis
Abstract:: An ecological study of a microorganism similar to that isolated in 1956 and designated as Micrococcus radiodurans indicated that the organism could be isolated from several different environments. By taking advantage of its radio-resistivity, high levels of gamma radiation were used in the isolation procedures to inactivate most of the...

The response of nitrifying bacteria to treatments of N-Serve and Roundup in continuous-flow soil columns

Creator:: Rhodes, Albert N.
Abstract:: This study examined the effects of Roundup [N-(phosphonomethyl) glycine] and N-Serve [2-chloro-6- (trichloromethyl) pyridine] on nitrifying organisms in static batch, perfusion soil columns, and a new continuous-flow soil column system. The continuous-flow method is new to nitrification studies and was shown to produce greater nitrifier activity than either static batch...

Salinity and temperature interactions and their relationship to the microbiology of the estuarine environment

Creator:: Morita, Richard Y., Jones, Larry P., Griffiths, Robert P., and Staley, Thomas E.
Abstract:: An estuary, unlike the open ocean, is a dynamic system that is continuously undergoing changes in its physical and chemical properties. Marked fluctuations in the levels and kinds of nutrients, temperature, and salinity are normally found in estuarine environments. These changes occur principally as a result of freshwater intrusions, tidal...

Growth and development of tetracycline resistant Chlamydia suis

Creator:: Lenart, Jennifer
Abstract:: Tetracycline is a front line antibiotic for the treatment of chlamydial infections in both humans and animals, and the emergence of tetracycline resistant (tet[superscript R]) Chlamydia is of significant clinical importance. Recently, several tet[superscript R] chlamydial strains have been isolated from swine (Sus scrofa) raised in production facilities in Nebraska....

Detection, identification, and antibiotic treatments of bacterial contaminants from micropropagated strawberries

Creator:: Tanprasert, Piyarak
Abstract:: Bacterial contamination is one of the most important problems both in plant tissue culture research and commercial laboratories. Early detection of contaminants saves time, effort, and money. Strawberry runner explants were screened for contaminants during June to August, 1994 and 1995. Most contaminants found were bacterial rather than fungal. Bacterial...

The disposition of four therapeutically important antimicrobial agents in llamas

Creator:: Murdande, Sharad B.
Abstract:: The disposition of four therapeutically important antimicrobial agents was studied in llamas following intravenous bolus administration. Six llamas were each given ampicillin, tobramycin, trimethoprim and enrofloxacin at a dose of 12 mg/kg, 1 mg/kg, 3 mg/kg and 5 mg/kg of body weight with a wash out period of 3 days...

Decoding DOM Degradation with Metatranscriptomics : How Do Sunlight and Microbial Communities Interact to Degrade Dissolved Organic Matter in Arctic Freshwaters?

Creator:: Nalven, Sarah G.
Abstract:: Arctic soils are warming, making vast stores of organic carbon available for conversion to CO₂. This could create a positive feedback loop and accelerate global warming, but the processes that convert this carbon into CO₂ are not well understood. We investigated how the combined activities of sunlight and microbes degrade...
