Towards the microbial production of a switchable solvent by using the enzyme indoleamine N-methyltransferase
DownloadSpring 2016
Switchable solvents are a novel class of chemicals that are characterized with the ability to reversibly switch specific properties with the addition/removal of a trigger. For instance, a solution of low ionic strength can become one of high ionic strength, and vice versa. Switchable solvents...

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...

Development and validation of a surrogate strain cocktail to evaluate bactericidal effects of pressure on verotoxigenic Escherichia coli
Download2015-01-01
Garcia-Hernandez, Rigoberto, McMullen, Lynn, Gänzle, Michael G.
Many strains of verotoxigenic Escherichia coli (VTEC) are highly resistant to pressure. To facilitate future studies to improve the elimination of VTEC by pressure processing of food, this study developed and validated a cocktail of non-pathogenic strains of E. coli with equal or higher...

Mechanisms of pressure-mediated cell death and injury in Escherichia coli: From fundamentals to food applications
Download2015
High hydrostatic pressure is commercially applied to extend the shelf life of foods, and to improve food safety. Current applications operate at ambient temperature and 600 MPa or less. However, bacteria that may resist this pressure level include the pathogens Staphylococcus aureus and strains...

Combining a PagP fusion protein system with nickel ion-catalyzed cleavage to produce intrinsically disordered proteins in E. coli
Download2015-01-01
Zahran, Somaya, Pan, Jonathan S., Liu, Philip B., Hwang, Peter M.
Many proteins contain intrinsically disordered regions that are highly solvent-exposed and susceptible to post-translational modifications. Studying these protein segments is critical to understanding their physiologic regulation, but proteolytic degradation can make them difficult to express and...

The Cpx envelope stress response of Escherichia coli regulates and is regulated by the small RNA RprA
DownloadFall 2015
When bacteria sense changes in their environment, they adapt by altering the expression of their genes in such a way that accommodates the change. To do this, bacterial cells can modulate the activity of their genes at either the level of transcription, or at the post-transcriptional level....

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...

Environmental Risk Factors Associated with Contamination of Private Drinking Water Wells with Escherichia coli
DownloadFall 2014
The focus of this research was to identify environmental risk factors that play a critical role in the contamination of drinking water wells with Escherichia coli. This study used data from a case control-study carried out between April 2005 and September 2006 in Ontario and Alberta, using...

Application of antimicrobials for the elimination of Escherichia coli and Listeria monocytogenes in brine injected beef
DownloadFall 2013
The application of antimicrobials to a brine-injected raw beef roast for the elimination/inhibition of heat resistant Escherichia coli and Listeria monocytogenes was investigated. The choice of antimicrobials for use in brine injected beef was based on minimum bactericidal concentration in brine...
