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...

Impact of carbohydrates and carnocyclin A on growth and gene expression of Listeria monocytogenes
DownloadSpring 2024
L. monocytogenes is the foodborne pathogen that causes listeriosis, which has a high fatality rate of 20 to 30%. L. monocytogenes is often associated with ready-to-eat food products. Therefore, techniques to control growth of this organism are needed for the safety of these foods....

Fall 2014
The growth of Listeria monocytogenes and spoilage microorganisms is a concern in sodium-reduced ready-to-eat (RTE) meats. To assess the microbial risk of sodium-reduced RTE meats, the microbiota of retail RTE meats was profiled and the growth of L. monocytogenes and an autochthonous microbiota...

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....

Influence of cyclopropane fatty acids on heat, high pressure, acid, and oxidative stress resistance in Escherichia coli
Download2016-01-01
Chen, Yuan Yao, Gänzle, Michael G.
Heat and high pressure resistant strains of Escherichia coli are a challenge to food safety. This study investigated effects of cyclopropane fatty acids (CFAs) on stress tolerance in the heat- and pressure-resistant strain E. coli AW1.7 and the sensitive strain E. coli MG1655. The role of CFAs...

Inhibition of Listeria monocytogenes growth and biofilm production by nisin and phenolic compounds.
DownloadFall 2017
The synergistic antimicrobial and anti-biofilm activities of nisin and phenolic compounds against Listeria monocytogenes were investigated. Among the twenty six phenolic compounds tested in this study, butyl gallate, octyl gallate, lauryl gallate, propyl gallate, naringenin and quercetin...
