Listeria monocytogenes is a foodborne pathogen of concern in meat products. Also, many fresh meat products packaged for retail sale with oxygen permeable films are prone to browning, leading to a decrease in sales. The first objective of this study was to investigate the inhibitory effect of C....

Shiga toxin-producing 𝘌𝘴𝘤𝘩𝘦𝘳𝘪𝘤𝘩𝘪𝘢 𝘤𝘰𝘭𝘪 (STEC) is a food-borne pathogen that causes acute gastroenteritis. It has a low infectious dose and children have an elevated risk of developing severe complications (e.g., hemolytic uremic syndrome). To prevent secondary spread, Alberta’s microbiological...

Stress is a major factor every organism needs to mitigate to survive. Environmental factors such as oxygen content, temperature, and alkalinity can all induce stress and prevent life from progressing. For Escherichia coli and other members of the mammalian gastrointestinal tract they need to...

Methane is the second most important greenhouse gas after carbon dioxide with a global warming potential over 100 years 25 times that of CO2. Today, anthropogenic sources of methane comprise 60% of the global methane budget per year and tools for mitigating emissions have become increasingly...

Acinetobacter baumannii remains a poorly understood, but very dangerous opportunistic pathogen. Though it lacks clear virulence traits expected of pathogens, it none the less poses a massive threat to the hospital system due to its inherent and acquired resistance to antibiotics, survival on...

Protein glycosylation, the covalent attachment of carbohydrates to amino acids, was once thought to be a unique attribute of Eukaryotes and select bacteria. However, both N- (attached to asparagine) and O- (attached to serine or threonine) glycosylation systems have been identified in an ever...

The type VI secretion system (T6SS) is a contact-dependent molecular weapon used by bacteria to transport a variety of effectors into neighbours. Attacked cells must have immunity proteins specific to each incoming effector in order to neutralize their cytotoxic effects. Vibrio cholerae, a...

The bacterial envelope is a critical barrier that not only shields bacteria from harsh environments but also serves as a key organizing centre for processes such as metabolism, virulence, and even DNA replication. In Gram-negative bacteria, the envelope is composed of inner and outer membranes...

Methylotrophic bacteria are ecologically widespread chemotrophs which utilize single carbon compounds as their primary energetic and assimilatory substrate for biomass. Those which utilize methane are commonly referred to as methane oxidizing bacteria (MOB), or methanotrophs. The majority of...

Alberta law requires reclamation of lands disturbed by surface mining operations, such as those occurring at the Athabasca Oil Sands Region, however, reclamation rates lag far behind continued disturbance rates. Due to cost, mining companies must make use of the materials on site, of which the...
