Antimicrobial Effects of Mentha pulegium Essential Oil on Listeria monocytogenes in Iranian White Cheese
Background: Listeria monocytogenes is an important Gram-positive disease-causing bacterium existing in milk and dairy products. Inhibitory effects of Mentha pulegium essential oil at concentrations of 0.03, 0.015, and 0.0075% on growth of L. monocytogenes were studied in Iranian white cheese during 60 days of storage. Methods: Essential oil of M. pulegium plant, collected from north of Iran,...
متن کاملModeling the growth of Listeria monocytogenes on the surface of smear- or mold-ripened cheese
Surface-ripened cheeses are matured by means of manual or mechanical technologies posing a risk of cross-contamination, if any cheeses are contaminated with Listeria monocytogenes. In predictive microbiology, primary models are used to describe microbial responses, such as growth rate over time and secondary models explain how those responses change with environmental factors. In this way, prim...

متن کاملThe Effect of Pediococcus pentosaceus Bacteriocin on Listeria monocytogenes in Soft Cheese
─Among antimicrobial materials produced by Pediococcus pentosaceus, bacteriocin have gained the greatest interest in food preservation as a natural substance. A bacteriocin producing P. pentosaceus was isolated from vegetables and human stool in a previous study. Purification, activity measurement, and characteristics of the bacteriocin was also determined. The yield of the bacteriocin was 9.08...
