Fall 2016
“Blown-pack” spoilage of beef by psychrotrophic Clostridium spp. occurs sporadically and resistance of the endospores to most interventions makes them very difficult to control. Current interventions used to control spoilage and pathogenic bacteria, such as acid washes and heat treatments, do...

Application of Anoxic-Aerobic Membrane Bioreactors (MBRs) for Oil Sands Process-Affected Water (OSPW) Treatment
DownloadFall 2016
The enormous volumes of oil sands process-affected water (OSPW) produced during oil sands bitumen extraction have been a public concern due to the toxicity and persistence of the organic contaminants contained in the water. Among all the contaminants in OSPW, naphthenic acids (NAs) are regarded...

Application of Ozone and Peroxone Processes for Naphthenic Acids Degradation in Oil Sands Process-Affected Water: Characterization of Water Before and After Treatment
DownloadFall 2017
Appling ozone (O3) with high doses (>100 mg/L) to remove naphthenic acids (NAs) from oil sands process-affected water (OSPW); limits its application and feasibility in the OSPW remediation. To decrease the required doses and their associated costs, this study examined the application of ozone...

Feed efficiency affects profitability and sustainability in beef production systems. Since ruminal microbes play essential roles in feed digestion and conversion, the overall objective of this project was to investigate the association between ruminal bacteria and feed efficiency of beef cattle....

Enterococcus faecalis 710C is a lactic acid bacterium that produces two bacterocins, ent7A and ent7B. Both ent7A and ent7B have strong activity against gram-positive food pathogens including Listeria spp., Clostridium spp., vancomycin-resistant enterococci (VRE) and methicillin-resistant...

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...
