Journal ArticleDOI
Nisin treatment for inactivation of Salmonella species and other gram-negative bacteria.
TL;DR: It is demonstrated that nisin is bactericidal to Salmonella species and that the observed inactivation can be demonstrated in other gram-negative bacteria.
Journal ArticleDOI
Bacterial Separation and Concentration from Complex Sample Matrices: A Review
Kelly A. Stevens,Lee-Ann Jaykus +1 more
TL;DR: The purpose of this review is to provide a detailed understanding of the science, possibilities, and limitations of separating and concentrating bacterial cells from the food matrix in an effort to further improve the ability to harness molecular methods for the rapid detection of foodborne pathogens.
Journal ArticleDOI
Effect of Treatment Conditions on Nisin Inactivation of Gram-negative Bacteria
TL;DR: The addition of bovine serum albumin to the treatments containing nisin and EDTA did not result in a significant decrease in inhibitory action, and all of the chelators examined exhibited some inhibitory activity.
Journal ArticleDOI
Antimicrobial action of nisin against Salmonella typhimurium lipopolysaccharide mutants.
TL;DR: The antimicrobial activity of nisin against outer membrane lipopolysaccharide mutants of Salmonella typhimurium LT2 was investigated and results indicated that the core oligosaccharide in lipopoly Saccharide plays a role in nisin sensitivity.
Journal ArticleDOI
Direct detection of bacterial pathogens in representative dairy products using a combined bacterial concentration-PCR approach
Kelly A. Stevens,Lee-Ann Jaykus +1 more
TL;DR: This work aims to develop a simple, rapid method to concentrate and purify bacteria and their nucleic acids from complex dairy food matrices in preparation for direct pathogen detection using polymerase chain reaction (PCR).
