Abstract:
... Air flow characteristics and decontamination efficacy are investigated within a forced-air ozone reactor designed to control Listeria monocytogenes on apple fruit. The commercial reactor introduced an air-ozone mix through a column of apples (540 kg contained within two bins; dimensions 1.21 m × 1.21 m × 0.72 m) for a defined air velocity and time period. The apple bed had high porosity (ɛ = 0.533 ...

Abstract:
... Glutathione is a low molecular weight thiol that is important for maintaining intracellular redox homeostasis. Some bacteria are able to import exogenous glutathione as a nutritional source and to counter oxidative stress. In cytosolic pathogens Burkholderia pseudomallei and Listeria monocytogenes, host glutathione regulates bacterial virulence. In B. pseudomallei, glutathione activates the membra ...
