Assessing biofilm formation by Listeria monocytogenes

Listeria monocytogenes(L. monocytogenes) is a serious food-borne pathogen for immunocompromised individuals. L. monocytogenes is capable of producing biofilm on the surface of food processing lines and instruments. The biofilm transfers contamination to food products and impose risk to public hea...
