Climate and air quality impacts of boreal wildfires — new analytical approaches for the investigation of light absorption and atmospheric reactivity of wildfire particulate matter
DownloadSpring 2022
Wildfire smoke emissions contain substantial amounts of light-absorbing aerosols that can affect the radiation and cloud processes, resulting in climate impacts on regional and even global scales. The radiative impact of these light-absorbing aerosols is largely contributed by brown carbon (BrC),...

Veeman, Michele M., Adamowicz, Wiktor
Public concern regarding food safety has emerged as a major policy issue. Chemicals and biotechnological processes are perceived as risks of food safety despite their contribution to an efficient, low cost agriculture and food industry. Increases in uses of biotechnological processes for foods...

Control of Listeria monocytogenes and Heat-Resistant Escherichia coli on Vacuum-Packaged Beef
DownloadSpring 2012
Novel methods to control Listeria monocytogenes and Escherichia coli on vacuum-packaged raw beef were investigated. Bacteriocin-negative Lactobacillus sakei FUA3058 and bacteriocin-positive Carnobacterium maltaromaticum UAL307 were tested as biopreservatives, alone or in combination with...

Contamination by lactic acid bacteria is a major source of inefficiency in the bioethanol industry. Contaminated fermentations exhibit lowered ethanol yields and contamination events often require shutdown of the entire process for cleaning and decontamination. The first objective of this study...

Effect of bacterial stress response on pathogen enumeration and its implications for food safety
DownloadSpring 2011
To determine the impact of stress response on enumeration, cell association status and the viability of Escherichia coli DH5α, Staphylococcus aureus ATCC 13565 and Listeria monocytogenes CDC 7762 were evaluated using fluorescence microscopy and were compared with the outcomes of traditional plate...

Examining the structure, function and mode of action of bacteriocins from lactic acid bacteria
DownloadSpring 2010
Carnocyclin A (CclA) is a remarkably stable, potent bacteriocin produced by Carnobacterium maltaromaticum UAL307. Elucidation of the amino acid and genetic sequences revealed that CclA is a circular bacteriocin. Preliminary structural studies (dynamic light scattering, NMR, circular dichroism,...

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...

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...
