This study characterized functions and metabolic profiles of cell-free supernatants (CFS) from Lactobacillus johnsonii KD1 against three foodborne pathogens: the Gram-negative bacteria Vibrio parahaemolyticus 3HP and Salmonella enterica serovar ...
Enterohemorrhagic Escherichia coli (EHEC) is a major foodborne pathogen capable of forming persistent biofilms on surfaces in meat processing environments, posing a risk of cross-contamination. This study aimed to evaluate the inhibitory potential of food-derived lactic acid bacteria (LAB) against E...
Cell-free supernatants (CFS) of Lactobacillus johnsonii KD1 exhibited inhibitory activity against the growth of foodborne pathogenic bacteria, including the Gram-negative bacteria Vibrio parahaemolyticus 3HP and Salmonella enterica serovar Typhimurium LT2, as well as the Gram-positive bacterium List...
Biogenic amine-producing bacteria are responsible for the production of basic nitrogenous compounds, such as histamine, cadaverine, tyramine and putrescine, after foods spoil due to microorganisms. In the present work, we applied a shotgun proteomics approach to quickly and easily characterize 15 di...
The alternative sigma factor sigmaB has an important role in the acquisition of stress-resistance in many gram-positive bacteria. In the foodborne pathogen Bacillus cereus sigmaB is activated strongly upon a heat shock and other stress conditions. Here we describe the identification of the set of si...
