Bacterial Biofilms: Formation, Properties and Its Prevention in Food Industry
Abstract
Biofilms are communities of microorganisms that are able to attach to
each other and to any surfaces by bacterial adherence. The ability of bacterial
biofilms to attach to each other and surfaces makes them to get advantages such
as protection from harsh environmental situation, increasing availability of
nutrients for growth, increasing binding of water molecules, reducing the
possibility of dehydration and transferring of genetic materials. They are
characterized by the production of an excessive network of highly hydrated
extracellular polymeric substances facilitating the initial bacterial
attachment to a surface, formation of micro colony and biofilm structure. The
biofilms formation on the food contact surface, in particular caused by different
pathogens such as Pseudomonas, Enterococcus species, Listeria
monocytogenes, Staphylococcus aureus, Escherichia coli and Salmonella species,
causes contamination of foods. The consequences of this situation always become
the fundamental problem of food safety, hygiene and quality.
