Effect of chitosan, and bacteriocin – Producing Carnobacterium maltaromaticum on survival of Escherichia coli and Salmonella Typhimurium on beef
Download2018-01-01
Hu, Zi Yi, Balay, Danielle, Hu, Ying, McMullen, Lynn M., Gänzle, Michael G.
The aim of this study was to investigate the synergistic effect of chitosan and bacteriocins against Escherichia coli and Salmonella in media and in lean beef. The inhibitory effects of chitosan and bacteriocins against E. coli AW1.7 and S. enterica Typhimurium in media were determined by a...

Effect of drying on oxidation of membrane lipids and expression of genes encoded by the Shiga toxin prophage in Escherichia coli
Download2020-01-01
Fang, Yuan, McMullen, Lynn M., Gänzle, Michael G.
Drying processes do not eliminate pathogenic Escherichia coli in foods but induce sublethal injury, which may also induce the Shiga toxin (Stx) prophage. This study investigated the effect of drying on membrane lipid oxidation and stx expression in E. coli. Lipid peroxidation was probed with...

Li, Hui, Garcia-Hernandez, Rigoberto, Driedger, Darcy, McMullen, Lynn M., Gänzle, Michael G.
The pressure resistance of Shiga-toxin producing Escherichia coli (STEC) depends on food matrix. This study compared the resistance of two five-strain E. coli cocktails, as well as the pressure resistant strain E. coli AW1.7, to hydrostatic pressure application in bruschetta, tzatziki, yoghurt...

Effects of nisin and reutericyclin on resistance of endospores of Clostridium spp. to heat and high pressure
Download2013-05-01
Hofstetter, Simmon, Gebhardt, David, Ho, Linda, Gänzle, Michael G., McMullen, Lynn M.
The effects of high pressure, temperature, and antimicrobial compounds on endospores of Clostridium spp. were examined. Minimal inhibitory concentrations (MIC) of nisin and reutericyclin were determined for vegetative cells and endospores of Clostridium sporogenes ATCC 7955, Clostridium...

Lethality of high-pressure carbon dioxide on Shiga toxin-producing Escherichia coli, Salmonella and surrogate organisms on beef jerky
Download2020-05-16
Schultze, Danielle M., Couto, Ricardo, Temelli, Feral, McMullen, Lynn M., Gänzle, Michael G.
Low water activity (aW) foods permit the survival of low-infectious dose pathogens including Escherichia coli and Salmonella. Desiccation of non-heat resistant E. coli and Salmonella enterica increases their heat resistance; therefore, alternative methods are necessary to ensure the safety of low...

The effect of growth temperature, process temperature, and sodium chloride on the high pressure inactivation of Listeria monocytogenes on ham
Download2016-01-01
Teixeira, Januana S., Maier, Maximilian B., Miller, Petr, Gänzle, Michael G., McMullen, Lynn M.
This study investigated the effect of growth temperature (8–32 °C), process temperature (−17 to 32 °C), and sodium chloride concentration (0–3 %) on the lethality of pressure to Listeria monocytogenes. Pressure treatments were performed using a 5-strain cocktail of L. monocytogenes. Cultures...

The locus of heat resistance (LHR) mediates heat resistance in Salmonella enterica, Escherichia coli and Enterobacter cloacae
Download2017-06-01
Mercer, Ryan G., Walker, Brian D., Yang, Xianqin, McMullen, Lynn M., Gänzle, Michael G.
Enterobacteriaceae comprise food spoilage organisms as well as food-borne pathogens including Escherichia coli. Heat resistance in E. coli was attributed to a genomic island called the locus of heat resistance (LHR). This genomic island is also present in several other genera of...

Transduction of stx2a mediated by phage (Φ11-3088) from Escherichia coli O104:H4 in vitro and in situ during sprouting of mung beans
Download2022-12-16
Fang, Yuan, Brückner, Luisa Linda, McMullen, Lynn M., Gänzle, Michael G.
Escherichia coli O104:H4 strain 11-3088 encoding Stx2a is epidemiologically related to the foodborne outbreak associated with sprouts in Germany, 2011. Sprouting provides suitable conditions for bacterial growth and may lead to transduction of non-pathogenic strains of E. coli with Stx phages....

Use of the fluorescent probe LAURDAN to label and measure inner membrane fluidity of endospores of Clostridium spp.
Download2012-10-01
Hofstetter, Simmon, Denter, Christian, Winter, Roland, McMullen, Lynn M., Gänzle, Michael G.
A method for measuring the fluidity of inner membranes of populations of endospores of Clostridium spp. with a fluorescent dye was developed. Cells of Clostridium beijerinckii ATCC 8260 and Clostridium sporogenes ATCC 7955 were allowed to sporulate in the presence of...
