This is a 4 step process that removes food waste, dirt, grease and destroys food-borne disease pathogens. Food-contact surfaces can be a great habitat for food-borne pathogens because food preparation surfaces are usually in contact with organic matter such as milk which is a good source of nutrients for microorganisms, with inorganic debris, with other microorganisms. A prep Station a prep Station a prep Station a prep Station a prep Station is the work center food! This fiber layer is called extracellular polymeric substances (EPS). Journal of Adhesion, 4, 155159. Surface properties of modern materials are usually inadequate in terms of wettability, adhesion properties, biocompatibility etc., so they should be modified prior to application or any. A gel phase is formed in biofilms in which bacteria live. It is nature of microorganisms to attach to wet surface, and form slimy layer composed of extracellular polymeric substances (EPS) to protect themselves from grazers and harsh environment. Cells also communicate between themselves to initiate antibiotic biosynthesis, and extracellular enzyme biosynthesis.
