Fall 2009
The objectives of this study were to determine the microbial ecology of “blown-pack” fresh beef obtained from a federally inspected facility and to use biopreservation to prevent spoilage of vacuum packaged chilled beef. Organic acids and alcohols in the purge obtained from the “blown” beef...

Combined Adsorption and Biodegradation Processes for Oil Sands Process-Affected Water Treatment
DownloadFall 2014
The oil sands process-affected water (OSPW) generated from bitumen extraction of oil sands by industries in Northern Alberta, Canada, is a great environmental concern because of the OSPW toxicity in the environment. This toxicity has been attributed to a group of alicyclic and aliphatic compounds...

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...

In order to determine the degradation of Naphthenic Acids (NAs) in oil sands process-affected water (OSPW), a series of semi-batch ozonation experiments have been conducted resulting in a maximum reduction of NAs greater than 99%. Compared to the high NAs removal, the reduction of both COD and...

Development and Validation of a Sclerotinia sclerotiorum-Specific Quantitative PCR Assay to Assess Risk of Sclerotinia Stem Rot of Canola (Brassica napus)
DownloadFall 2016
Sclerotinia stem rot, caused by Sclerotinia sclerotiorum, is a major disease of canola (Brassica napus) commonly managed by the routine application of fungicides. Petal infestation is an important stage of the disease cycle and has been the focus of previously developed Sclerotinia stem rot risk...

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...

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 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...
