Appendix 2<br />

Colour index<br />

High outlier<br />

Low outlier<br />

Appendix 2 - Table 5 displays the optical density bi<strong>of</strong>ilm formed 3 replicate<br />

wells for each for 6 Salmonella enterica subspecies enterica serovar Agona<br />

strains, 6 S. Typhimurium strains and 2 S. Enteritidis strains examined. The<br />

optical density was measured at 590 wavelengths (OD 590 ). Each strain was<br />

examined in triplicate wells in the microtitre plate (wells 1-3). The<br />

experiment was performed on three occasions (Run 1-3). The high outliers<br />

are denoted by yellow coloured cell and the low outliers are denoted by<br />

blue coloured cell. The mean <strong>of</strong> all 9 observations for each strain was also<br />

calculated. These mean calculations are based on the bi<strong>of</strong>ilm density<br />

formed over 168 hours at 37°C.<br />
