Biofilm Microbes Online Journals

  Microbial Biofilms have  considerable interest in the context of food hygiene. Of special significance is the ability of microorganisms to attach & grow on food and food-contact surfaces under their favourable conditions. Biofilm formation is a dynamic process and different mechanisms are involved in their attachment and growth on food surfaces . Extracellular polymeric substances play an important role in the attachment and colonization of microbes  to food-contact surfaces.The EPS synthesized by microbial cells consist of  proteins,polysaccharides,glycolipids,  glycoproteins and in some cases extracellular DNA(Deoxyribonucleic Acid). These substances form a network that influence the density, porosity, water content, sorption,charge,hydrophobicity & mechanical stability of biofilms. Various techniques have been adopted for the proper study & understanding of biofilm attachment and its control. If the microorganisms attached to  food-contact surfaces are not completely removed, they may lead to formation of biofilm and also increase the biotransfer potential.In addition, bacteriocins & enzymes are gaining importance and have an unique potential in food industry for effective biocontrol and removal of biofilms.
