Choice of micro-organism
Prevention of micro-organisms adhesion with the plasma process

The baker's yeast Saccharomyces cerevisiae was chosen as the biological model because :

• its intensive use in the agri-food and biotechnology sectors;

• its identification as a potential source of contamination in many food products;

• its definition as a target micro-organism in European regulations on surface hygiene;

• its high resistance to biocides, which is further enhanced by prior adhesion to stainless steel;

• and its ability to adhere to different substrates and form biofilms.
