Transcriptome profiling of Nitrosomonas europaea grown singly and in co-culture with Nitrobacter winogradskyi

Creator:: Pérez, José
Abstract:: In most environments, ammonia (NH₃) is oxidized to nitrate (NO₃⁻) via the intermediate nitrite (NO₂⁻). This is a microbe-driven process involving phylogenetically distinct types of microorganisms, namely, ammonia-oxidizing bacteria (AOB) and Thaumarchaea (AOA), and nitrite-oxidizing bacteria (NOB). Nitrosomonas europaea and Nitrobacter winogradskyi are the best studied AOB and NOB, respectively,...

Transcriptome Responses of the Nitrifying Bacteria Nitrosomonas europaea and Nitrobacter hamburgensis to Low Oxygen

Creator:: Dobie, Michael
Abstract:: Nitrification is the process within the global Nitrogen Cycle where ammonia (NH3) is oxidized to nitrate (NO₃⁻) and can be carried out by two distinct groups of bacteria. The ammonia-oxidizing bacteria (AOB) first oxidize NH₃ to nitrite (NO₂⁻), and second, the nitrite-oxidizing bacteria (NOB) oxidize NO₂⁻ to NO₃⁻. In aerobic...

Carbon Aerogel-Supported Nickel and Iron for Gasification Gas Cleaning. Part I: Ammonia Adsorption

Creator:: Gomez-Capiro, Oscar, Hinkle, Adrian, Delgado, Aaron M., Fernandez, Camila, Jimenez, Romel, and Arteaga-Perez, Luis E.
Abstract:: Biomass gasification is a promising way to obtain green energy, but the gas composition makes it unsuitable for use in traditional technologies (i.e., IC engine). Gas purification over nickel and/or iron catalysts is an attractive alternative. Cellulose-based carbon aerogels (CAGs) have shown suitable physical chemical properties for use as catalyst...

Bacterial and Host Factors Contributing to Mycobacterium avium subspecies paratuberculosis Persistent Infection

Creator:: Phillips, Ida L.
Abstract:: Mycobacterium avium subspecies paratuberculosis (MAP) is the causative agent of Johne’s disease, a chronic granulomatous enteritis that plagues domestic and wild ruminants globally. During the silent stages of Johne’s disease, infected animals intermittently shed bacteria for years prior to clinical diagnosis during advanced disease stages. This strategy allows MAP to...

An Examination of Factors Controlling the Activity of Ammonia- and Nitrite-oxidizers in Diverse Soils

Creator:: Giguere, Andrew T.
Abstract:: Nitrification is a critical step in the global nitrogen cycle involving the biological oxidation of ammonia (NH₃) to nitrite (NO₂⁻ ) and then to nitrate (NO₃⁻). The first step in nitrification is carried out by NH₃-oxidizing bacteria (AOB) and archaea (AOA), and the second by NO₂⁻-oxidizing bacteria (NOB). In addition...

Creator:: Pérez-Pérez, Marcos, Garza-Gil, Dolores, Varela-Lafuente, Manuel, and Surís-Regueiro, Juan
Abstract:: The aim of this work is to develop a predator-prey model for two species of commercial importance captured by the European fishing fleet in the European Grounds. In this model, the hake (Merluccius merluccius) represents the predator, and the blue whiting (Micromesistius poutassou) is the prey. Both the predator and...

Quantitative trait locus analysis of agronomic and malting quality traits in the Harrington x Morex barley (Hordeum vulgare L.) mapping population

Creator:: Marquez-Cedillo, Luis A.
Abstract:: Characterization of the determinants of economically important phenotypes showing complex inheritance should lead to more effective use of genetic resources. This study was conducted to determine the number, genome location and effects of QTLs determining malting quality and agronomic traits in the two North American barley quality standards. Using a...

Influence of commensal microorganisms on Clostridium botulinum type E.

Creator:: Patrick, Lui-sun Kwan
Abstract:: Achromobacter A43 produced a compound inhibitory to the outgrowth of Clostridium botulinum type E spores. The inhibitor could be produced in various laboratory media and the outgrowth of germinated spores was completely inhibited by 1/10th dilution of the A43 spent medium. Germination was not affected. The spores lost refractility in...

Factors that motivate Latino students to pursue higher education in selected colleges in the state of Oregon

Creator:: Meza Discua, José Luis
Abstract:: Latinos are the largest and most rapidly growing ethnic minority in the United States, and they have the highest dropout rates of any major ethnic group in the country (U.S. Department of Labor, 2003). Latinos' educational attainment is consistently lower than that of other students (Gandara, 2008). The majority of...
