- ... oil exhibited quicker initial reductions of bacteria than free thyme oil in tryptic soy broth (TSB) and 2% reduced fat milk at 21°C, due to the improved dispersibility of thyme oil. In TSB with 0.3g/L thyme oil, it took less than 4 and 8h for two nanoemulsions and free oil, respectively, to reduce Escherichia coli O157:H7 and Listeria monocytogenes to be below the detection limit. The emulsified ...

Then cocktails of Listeria monocytogenes, Salmonella or Escherichia coli O157:H7 were spread plated on the supplemented agar and observed for growth after 24 and 48 h at 35C. Fermentates C and D, lauric arginate (LAE), and lactoperoxidase inhibited growth of all pathogens on milk agar ...

AIMS: To evaluate natural terpene compounds for antimicrobial activities and determine whether these compounds could be used to control microbial activities and pathogens in production animal facilities. METHODS AND RESULTS: Thymol, geraniol, glydox, linalool, pine oil, plinol and terpineol were tested in laboratory studies for ability to control the production of odorous volatile fatty acid compo ...
