My research project
Biofilm formation of Listeria monocytogenes on a novel triphasic viscoelastic food model and the application of a novel mild preservation technique; cold plasma
Listeria monocytogenes is one of the rising pathogenic threats in food industry because of its characteristics. This bacterium is able to grow at refrigerating temperatures and it is a biofilm former. These abilities makes the bacterium more persistent and more resistance in its environment. Especially its behaviour on viscoelastic biotic surfaces are not very well studies in literature. Therefore my project focusses on the behaviour and biofilm formation of L. monocytogenes on a triphasic viscoelastic food model. Another contributing factor is that food industries are trying to find new preservation techniques which do not interact or change the food itself. One novel technology complying with these demands is cold plasma. Cold plasma is known to have antibacterial and antibiofilm properties. The novelty for my project is the application of cold plasma on a biotic surface with L. monocytogenes biofilms and the combination with different co-cultures or with the addition of other natural antimicrobials; like nisin.
