Mechanisms of pressure-mediated cell death and injury in Escherichia coli: From fundamentals to food applications
Download2015
High hydrostatic pressure is commercially applied to extend the shelf life of foods, and to improve food safety. Current applications operate at ambient temperature and 600 MPa or less. However, bacteria that may resist this pressure level include the pathogens Staphylococcus aureus and strains...

Membrane lipid homeostasis and stress resistance in Escherichia coli and Lactobacillus plantarum
DownloadSpring 2017
Food processing, preservation and storage impose stresses on food bacteria. The maintenance of membrane lipid homeostasis through modification of phospholipids is a key strategy for bacteria to adapt environmental changes and survival in food. Mechanisms of adaptation are generally comparable...

Microbiological quality of organic vegetables produced in soil treated with different types of manure and mineral fertilizer
Download2006
Maia, Carla M., Carvalho, Isabel D., Serafini, Álvaro B., da Silva, Natan F., André, Maria C. P. B., Machado, Débora C.
An attempt was made to evaluate microbiological quality of horticultural crops grown organically. Three species of vegetables were used, lettuce (Lactuva sativa), radish (Raphanus sativus) and spinach (Tetragonia expansa), grown organically, in fertile soil. Six different treatments were applied:...

Molecular Mechanisms Used by Auxiliary Regulator NlpE to Signal the Cpx Envelope Stress Response in Escherichia coli
DownloadSpring 2017
The Cpx two-component system senses and mediates adaptation to envelope stresses in Escherichia coli. NlpE is an outer membrane lipoprotein that senses surface adhesion and signals the Cpx pathway. This work focused on investigating the molecular mechanisms used by NlpE to signal the Cpx pathway...

Monitoring Macrophage Immune Gene Expression Profiles as an Early Indicator System for Examining the Bioactivity of Oil Sands Process Affected Waters
DownloadFall 2021
Oil sands process-affected waters (OSPW) are by-products of bitumen (i.e. oil) extraction from the oil sands located in northern Alberta. These large volumes of water are held in tailings ponds and cannot be released due to their potential toxic effects. Overall, tailings ponds and mining...

High pressure processing (HPP) is a non-thermal processing technology aimed to inactivate bacteria and improve the shelf life of food. Commercial parameters for ready-to-eat (RTE) meat products are 600 MPa for 3-7 min at cold or room temperatures. Many regulatory agencies require a 5-log...

Fall 2017
Gram-negative bacteria are separated from the environment by a multilayered structure known as the envelope, which is comprised of the outer membrane, the inner membrane and the aqueous periplasmic space that lies between the two membranes. Biogenesis of the envelope is a complex process that...

Self-cycling fermentation (SCF) is an advanced, automated, semi-continuous fermentation strategy that is used to improve the volumetric productivity of bioproduction. Typically, a microbial culture is grown in a reactor and half the reactor contents are harvested once a limiting nutrient is...

Structure and function relationships of the binding of β- and ɑ-galactosylated oligosaccharides to K88 fimbriae of enterotoxigenic Escherichia coli
Download2018-01-01
Yan, Ya Lu, Gänzle, Michael G.
Chitosan-oligosaccharides (COS) are suitable acceptors for β-galactosidase, and galactosylated-COS prevent adhesion of enterotoxigenic Escherichia coli (ETEC) K88 to porcine erythrocytes. The structure and functional relationship of oligosaccharide binding to ETEC K88 fimbriae was investigated....
