Biofilm growth in the packaging hall

Biofilms usually consist of water, microorganisms and extracellular polymeric substances (EPS). These EPS react with water to build-up hydrogels. The hydrogels form a slime that coats the microorganisms inside. Within that coating nutrients, metabolites, or further substances may be present. The EPS consist of polysaccharides, proteins, lipids and nucleic acids. 

Therefore, the following prerequisites for biofilm growth can be summarized  

Next to the product, residues in returned bottles, grease or lubricants can also serve as substrate for bioflim growth when transferred to suitable surfaces. The mentioned fluids may also serve for the build-up of a conditioning film. 

The presence of bioflhns automatically leads to higher risks of product contamination throughout the complete production process. Single cells or whole biofihn 

A recent research project targeted the brewery-specific identification of microorganisms found in local biofihn stracmres. As the main inhabitants of the fully grown biofihns that were analyzed, various wild yeasts were detected. In single cases, also lactic acid- or acetic acid-producing bacteria were detected.
