Heat and Pressure Resistance of Escherichia coli and Its Inactivation In the Presence of Antimicrobial Compounds
DownloadFall 2014
Verotoxigenic Escherichia coli (VTEC) are pathogens causing severe foodborne disease. E. coli AW1.7 is a heat resistant beef carcass isolate that may be used as a surrogate organism to study the survival of VTEC on food. This dissertation examines the heat and pressure resistance of E. coli and...

Escherichia coli and Salmonella are contaminants in meat products and pose a risk for foodborne illness. Thermal lethality is the traditional method for controlling pathogens in meat products. It is recommended that ground beef and poultry products be cooked to internal temperatures of 71°C and...

Fall 2011
The mechanism of heat resistance in an exceptionally resistant strain of E. coli was investigated. E. coli AW1.7 was compared to a heat sensitive strain, E. coli GGG10. The heat resistance of both strains was increased by inclusion of NaCl, but only E. coli AW1.7 exhibited a consistent heat...

Fall 2016
Patterns of microbial host specificity have been observed at all host-related taxonomic levels, and several studies have demonstrated that Escherichia coli (E. coli) appears to display some level of host adaptation and specificity. Colonization of the gastrointestinal tract by E. coli largely...

Inactivation of Escherichia coli Using Electrochemical Disinfection with Potassium Periodate (KIO4)
DownloadSpring 2020
Electrochemical disinfection of water has drawn attention in recent years as an alternative for conventional chlorine-based water treatment, due to the generation of toxic disinfection by-products (DBP) during chlorination, and increased antibiotics resistant, chlorine resistant and virulent E....

Membrane lipid homeostasis and stress resistance in Escherichia coli and Lactobacillus plantarum
DownloadSpring 2017
Food processing, preservation and storage impose stresses on food bacteria. The maintenance of membrane lipid homeostasis through modification of phospholipids is a key strategy for bacteria to adapt environmental changes and survival in food. Mechanisms of adaptation are generally comparable...

Molecular Mechanisms Used by Auxiliary Regulator NlpE to Signal the Cpx Envelope Stress Response in Escherichia coli
DownloadSpring 2017
The Cpx two-component system senses and mediates adaptation to envelope stresses in Escherichia coli. NlpE is an outer membrane lipoprotein that senses surface adhesion and signals the Cpx pathway. This work focused on investigating the molecular mechanisms used by NlpE to signal the Cpx pathway...

New insights about barnacle reproduction: Spermcast mating, aerial copulation and population genetic consequences
DownloadSpring 2014
Barnacles are mostly hermaphroditic and they are believed to mate via copulation or, in a few species, by self-fertilization. However, isolated individuals of two species that are thought not to self-fertilize, Pollicipes polymerus and Balanus glandula, nonetheless carried fertilized...

Spring 2016
Polar bears (Ursus maritimus) were among the first large mammals to be assessed for genetic variation in the wild, and they remain a common subject of genetics studies. Although recent advances in genotyping technology have allowed for more accurate determination of population structure and the...

Fall 2023
High pressure processing (HPP) is a non-thermal processing technology aimed to inactivate bacteria and improve the shelf life of food. Commercial parameters for ready-to-eat (RTE) meat products are 600 MPa for 3-7 min at cold or room temperatures. Many regulatory agencies require a 5-log...
