Influence Of Environmental Conditions On Biofilm Formation Of Listeria Monocytogenes, Jing Li
All Theses
L. monocytogenes is a Gram-positive bacterium, ubiquitously distributed in the environment. It is the etiologic agent of listeriosis, a food-borne disease affecting humans and a variety of vertebrates. L. monocytogenes can form biofilm which is a multi-cellular layer of adherent bacteria surrounded by an extracellular polysaccharide matrix. Biofilm bacteria are extremely resistant to sanitizers and are difficult to be eradicated, therefore posing a big challenge to food processing industry and food service department.
In this work, we tested the biofilm formation in a number of L. monocytogenes serotypes under different environmental conditions, such as temperatures, pH and media (BHI, LB, …
